13.65  SHIP’s BELL CLOCK.  Genuine turn-of-the-last-century American ship’s bell clock by the venerable SETH THOMAS clock company as prominently marked on the dial between the two winding arbors.  It is further marked “MADE IN U.S.A.” below the “6.”  This handsome clock  features a silvered brass dial with bold Arabic numerals and a minute chapter ring swept by blued steel spade hands.  The subsidiary seconds bit showing single seconds marked by 10’s is set below the “12.”.  A manual “STRIKE” lever is provided at the “9” o’clock position to set the bell sequence and the Fast/Slow lever adjustment is also just below the “12.”   The classic flared ship’s clock case has a hinged bezel with its original glass crystal hinging on the right, opening and closing on the left with a press fit.  The lovely solid brass case contains a screen on the bottom to emit the sound produced by the internal brass bell.  The clock strikes the ship’s clock sequence properly with a loud, clear tone.  The tone is especially rich because it is made on an actual bell and not a gong as in many other “bell” clocks.  7 inches in diameter by 4 ¼ inches deep.  Cosmetically fine condition.  The case is flawless.  The silver dial has just enough wear and patina to belie its 100+ year old age.  Runs approximately 2 days on a single wind.  Complete with period winding key.   595

13.60  EARLY 8-DAY CHRONOMETER by FAMOUS MAKER.   Without question, one of the finest chronometers offered for sale in the world today.  This impressive marine timekeeper was made by “A. Johannsen 147 Minories London” as beautifully engraved in fancy script.  The large silvered brass dial has bold Roman numerals and a minute chapter.  The oversized subsidiary seconds bit is over the VI indicating single seconds marked by 10’s.  Within, it bears the mark “No.  1040.”  At the top, under the XII, the ~UP~ DOWN winding indicator is marked  0 to 8 and reads “WIND” at the 7 sector.  The dial is swept by magnificent solid gold spade hands.  The circumference has a silvered reflector ring protected by a thick beveled glass crystal.  It is set in a knurled brass bezel.  Unscrewing the bezel reveals the massive movement within.  It has decoratively engine-turned plates, a large bi-metallic balance with timing weights, blued steel helical hairspring, diamond end stone, spring détente escapement, and of course a chain drive fusee.   Interestingly the balance is protected by a crescent-shaped shield which would prevent this delicate and complicated piece of machinery from being damaged should the chain let go.  The movement is housed in its beautiful bright brass bowl slung in gimbals and mounted within its large brass-bound solid rosewood box.  The bottom of the bowl contains a spring-loaded winding dust cover.   The classic oversized 3-tier box contains the pivoting gimbal lock on the right front and the original ratcheted chronometer winding key on the rear bottom tier.  It is complete with brass skeleton lock and inlaid ivory number disc engraved with the matching serial number “1040.”  The middle tier is glazed on top and bears the inlaid ivory marker’s disc on the front engraved “A. Johannsen  LONDON.”   A star burst escutcheon encircles a button latch which engages the solid rosewood lid with brass inlay.  Both upper tiers are fitted with lid stops.  The sides of the lower box have stout folding brass drop handles for carrying.  The chronometer itself measures 5 ¾ inches in diameter.  The box is 8 by 8 inches and is 8 ½ inches tall.  Excellent original condition throughout and an excellent timekeeper. SOLD

Asmus Johannsen was considered an elite English maker in the mid-19th century.   He moved to his 149 Minories address in 1865.  Born in Denmark, he was chronometer maker to the Royal Navies of Italy, Spain, Portugal, and the Imperial Navies of Austria and China.  He constantly figured in the Greenwich trials and was awarded two First Places.  Tony Mercer, author of “Chronometer Makers of the World,” speaks of him, “A great maker, supplying many ‘makers’ with movements.”  Mr. Mercer provides a Johansen number time line starting with number 1867 which dates 1870.  Clearly this chronometer is much earlier.

As war clouds gathered around the world in 1940, it became apparent that the United States would soon be drawn into a world-wide conflict. Such involvement would require a massive fleet of Navy and merchant vessels plying the vast oceans. Such deployment required accurate navigation, which up to that time was only feasible using a chronometer for accurate timekeeping at sea. The U.S. Government, acutely aware of the impending need, sent out an urgent request to clock and watchmakers of the era to produce an adequate time keeper. The Hamilton Watch Company of Lancaster, Pennsylvania, which had never produced a full size chronometer before, stepped up to the call with its famous Model 21 in 1941. This splendid precision instrument was inspired by the Swiss chronometer made by Ulysee Nardin. In fact the first 300 chronometers produced by Hamilton mimicked the Nardin box with lock and key. Thereafter Hamilton went with the more familiar button latch assembly. Hamilton also took the basic design of the Nardin movement and then made several notable improvements. Perhaps the most innovative feature of the Model 21 was its use of interchangeable parts. This made manufacturing and maintenance much more efficient. Another was its use of Elinvar in the balance. Elinvar is not affected by changes in temperature, a fact that had plagued chronometer makers for more than a century. In the end Hamilton effectively manufactured over 13,000 of these marvelous machines for Navy and civilian use, prompting the boast, “The chronometer that won the war.” This example represents the top 1%.

13.15 WWII MERCHANT CLOCK. Authentic World War II ship’s clock made for the U.S. Maritime Commission by the venerable Seth Thomas clock company.

This clock is an good time keeper and is in excellent cosmetic condition showing signs of its actual wartime use. 7 ¾ inches in diameter. Complete with period winding key. SOLD

The United States Maritime Commission was an agency of the Federal Government created by the Merchant Marine Act passed on June 29, 1936. It replaced the United States Shipping Board (U.S.S.B.) which dated from World War I. The Merchant Marine Act formulated a Long Range merchant shipbuilding effort to design and build five hundred modern cargo ships. These were intended to replace the World War I era vessels which comprised the bulk of the United States Merchant Marine at the time. The Maritime Commission was also tasked with administering a subsidy program to build and operate ships under the American flag. Further it created the United States Maritime Service for training Merchant Marine officers to man the fleet.

In the late 1930's, several dozen merchant ships were built for the Commission under the original 500 shipbuilding program. Then in the late fall of 1940 the Emergency Shipbuilding program came into being, in order to support a lifeline to Great Britain and nationalize American shipbuilding in the event of war.

The first existing vessel undertaken by the Merchant Marine Act was the mighty SS AMERICA, owned by the United States Lines, which had operated in passenger service since 1940. When war appeared imminent, AMERICA was requisitioned by the U.S. Navy on June 1, 1941 and renamed USS WEST POINT for use as a troop carrier.

From 1939 through the end of World War II the U.S. Maritime Commission funded and administered the largest, most successful merchant shipbuilding effort in history. Thousands of ships, including Liberty ships, Victory ships, tankers and freighters were produced. Many were converted to Navy auxiliaries, notably attack cargo ships, attack transports, escort aircraft carriers, and tankers which became fleet replenishment ships. The Commission also was tasked with the construction of many hundreds of U.S. Navy ships including LST's, Tacoma-class frigates and troop transports. By the end of the war, U.S. shipyards had built a total of 5,777 merchant and naval ships under Maritime Commission auspices.

Upon the cessation of hostilities in World War II, the Emergency and Long Range shipbuilding programs were ended. In 1946, the Merchant Ship Sales Act was passed to sell off the Post-War surplus of ships to commercial buyers. Ships not sold under the Ship Sales Act were placed into one of eight National Defense Reserve Fleet (NDRF) sites maintained on the Atlantic, Pacific and Gulf coasts.

The U.S. Maritime Commission was officially disbanded on May 24, 1950.

In his second book on the topic of Chronometers, Whitney authored "Military Timepieces," 1992, AWI Press, Cincinnati, Ohio.  On pages 396-7 he writes, "These beautifully designed watches were truly remarkable timepieces, the performance of which was outstanding.  The two design features which contributed most to the superior performance of their chronometer watch were: 1) the unusually long mainspring, and 2) the design and construction of the balance assembly with unique biaxial thermal expansion rim of 18% nickel silver, invar arm and Hamilton Elinvar hairspring."

13.53 PROTOTYPE CHRONOMETER. Offered here is a very rare early example of the renowned World War II ship’s chronometer developed for the U.S. Navy by the Hamilton Watch Company. This lovely state-of-the-art precision timekeeper features a full 85 size ship's chronometer with silvered dial, 56 hour UP/DOWN indicator, blackened steel spade hands, bold Arabic numerals, and subsidiary seconds bit. The dial is signed "HAMILTON, LANCASTER, PA, U.S.A.” but is devoid of the typical serial number. The high grade movement is a work of art, with beautifully finished damascened nickel brass plates, the large innovative Elinvar-metallic balance, jeweled pivots, spring detente escapement, and of course a chain drive fusee. The movement bears the matching signature "Model 21, 14 Jewels, Hamilton Watch Co. Lancaster, Penna, Made In U.S.A.," again with no movement number. The movement is fitted into the solid brass bowl or "tub" with spring-loaded dust cover, slung in gimbals within the box, and equipped with a knurled gimbal lock. One of the unique features of this presentation is that the chronometer and gimbal are housed in a Ulysee Nardin box, still bearing the Swiss maker’s number “4220” on the lower tier! The middle tier bears Hamilton’s standard box label reading "HAMILTON WATCH CO. Lancaster, PA., U.S.A.” The box also has the Nardin feature of box lock and key. The lovely brass-bound box is of rich crotch-grained mahogany (nicer than later Hamilton’s) in a natural finish which contrasts beautifully with the distinctive brass “whale tail” box corners. All fittings are of solid brass including the box stays, button latches, folding drop handles and hinges. But unlike Hamilton’s later production the dust rail is of ebony, not brass. This fine chronometer is in near mint condition inside and out -- hard to believe it is over 75 years old! It is completely functional and comes with its earlier Nardin-style ratcheted winding key. The box measures 7 ½ inches cubed and the chronometer is 5 inches in diameter. But if this were not enough, it also comes complete with an original mahogany outer carrying case of the finest quality. It has a padded green felt interior, brass hinges, a hook and eye closure and retains its sturdy leather carrying strap. The oblong base measures 13 inches wide by 10 ½ inches deep. The outer box itself is 10 ½ by 10 ½ 10 inches high. A rare early example of the ultimate American marine timepiece. Truly investment quality. Not to be compared to later "production" models. 3495 Special PackagingBack to Top

13.51  IMPORTANT EARLY CHRONOMETER.  Two day marine navigational timekeeper by one of England’s most revered makers.  The handsome silvered brass dial is skillfully hand-engraved  “CHARLES FRODSHAM 84 Strand LONDON No. 3313.”  It bears two lovely cartouches consisting of a crown above an anchor, one reading “By Appointment to the Queen” and the other “Gold Medal Honour Paris EXN 1855.”  It has bold Roman numerals and a minute chapter marked in 5 minute increments.  The large subsidiary seconds bit marked by 10’s obscures the VI.  The 56 hour Up/Down indicator is below XII and is marked “Wound Up/ Not Wound.”  The hand rotates counter clockwise contrary to most chronometers.  The dial is swept by delicate solid gold spade hands.  The movement, in a word, is magnificent.  It has decorative spotted plates in a bright finish, complemented by brilliantly blued steel screws and a diamond end stone on the balance cock.  The top plate is elegantly signed in engraved script “Charles Frodsham London.”  It has a bi-metallic balance, early style pie-shaped timing weights, a blued steel hairspring and of course a chain driven fusee.  Of special note is its very unusual auxiliary compensation consisting of brass spheres, one on each side of the balance arm.  This feature is of great importance and entirely unique to Frodsham’s historical and innovative output.  The special movement is contained in its brass chronometer bowl with gimbal.  The bottom of the bowl has a rotating spring-loaded dust cover for winding.  It is housed in a simple rich African mahogany box with gimbal lock and box lock with skeleton key in the lower tier.   The middle tier has an inlaid ivory disc.  Above it is the button latch with sun burst escutcheon locking the lid.  The lid has an inlaid brass shield.  Each side of the box has inlaid folding brass handles.  It measures 7 inches square by 7 ¾ inches high.  The interior of the middle tier bears the antique trade label of “H.G. BLAIR & Co. Cardiff, Chronometer Makers and & Opticians Est. 1829” with decorative images of an early chronometer and sextant.  This chronometer is complete with it exceptional early winding key, which in itself is worth hundreds of dollars.  Totally complete and in good working order.  7950 Special PackagingBack to Top

Attached to the front of the chronometer box is the hand-written label from Castle & Co., Hull reading “TARNO.”  The TARNO was a general merchant ship launched in 1900.

13.21 EARLY SHIP'S BELL CLOCK. Genuine early 1900's American ship's bell clock made by Seth Thomas of Thomaston, Connecticut. This quality ship's clock has a silvered brass dial with bold black Roman numerals, blued steel spade hands, minute chapter ring and a seconds bit showing individual seconds below "XII." The dial is signed "SETH THOMAS" between the two winding arbors and is further marked "Made In U.S.A." below "VI.". The Fast/Slow adjust lever is above the 12 o'clock position and the manual strike lever marked "Strike" is left of "IX." The glazed hinged bezel with reflector ring opens from the left with a tight press fit. The case is the classic ship's clock type with flared bezel and is all brass in its original nickel finish. There is a screen at the bottom of the clock which allows maximum bell sound and it does so, ringing the ship's bell sequence properly with a loud, clear tone. The clock has just been thoroughly overhauled by a professional AWI-certified watchmaker and is in tip top condition. It is considered a 48 hours type. But in our possession since servicing, it has run 4 days on a single winding. 7 inches in diameter and 4 inches deep. Circa 1910. Excellent original condition showing wonderful age and absolutely no abuse. 495

13.49  ROYAL NAVY RESEARCH CHRONOMETER.  Very scarce 2-day marine chronometer made by the venerable English chronometer making firm of Thomas Mercer for the Royal Navy as boldly engraved on the silvered brass dial.  It reads, “20134 THOMAS MERCER ADMIRALTY NO: 6472.”  Then at the VI o’clock position it is engraved “Thomas Mercer Ltd. St. Albans Eng.”  This handsome marine timekeeper has bold Roman numerals and a minute chapter swept by particularly beautiful blued steel spade hands.  The standard 2-day (56 hour) Up/Down indicator is below the XII.  The subsidiary seconds bit below the center arbor shows single seconds marked by 10’s.  In a very unusual departure from most chronometers the seconds wheel and components of the movement are visible through a “window” in the center of the seconds bit!  This chronometer has the rare feature of being a “break circuit” type, meaning it was used in hydrographic survey applications when sightings needed to be timed and/or coordinated.  To these ends a small electrical détente is positioned on the seconds wheel to detect the precise passage of each minute of time.  The window then, allows the observer to directly view the workings of this electrical take-off feature.  The dial is protected by its heavy brass bezel with silvered reflector ring and beveled glass.  The all brass jeweled movement is a thing of beauty with decoratively-spotted plates and balance cock, diamond end stone,  a large compensated bi-metallic balance with timing weights, helical Palladium hairspring, spring détente escapement and of course a chain drive fusee.  The movement and bowl are stamped with matching numbers “20134.”  As mentioned, this chronometer has an electrical take-off feature which is in evidence on the reverse side of the dial where contacts meet the interior of the bowl and lead to the exterior of the tub.  There, they stand as insulated terminals with knurled screws for attachment to wiring.  The heavy brass tub is complete with its protective spring-loaded winding dust cover on the bottom and its original gimbal.  The exposed brass surfaces retain about 90% of their original protective orange lacquer.  This chronometer is in excellent overall cosmetic and running condition.  A real rarity at a very real low price.  2500

In our experience in handling literally hundreds of chronometers, this is the first we have encountered which bears the Admiralty’s name and serial number on the dial.  Typically a chronometer dial will bear the British military’s “broad arrow” mark, with some makers boasting “Maker to the Admiralty.”  According to Mercer serial numbers, this chronometer dates to 1952.

13.48 19th C. AMERICAN SHIP’s CLOCK.  Rare, late 1800’s ship’s clock made by the venerable Seth Thomas Co. of Thomaston Connecticut as marked above the center arbor on the porcelain dial, “‘SETH THOMAS.”  This very high quality clock has a perfect porcelain dial with Roman numerals and minute chapter swept by fancy spade hands.  A subsidiary seconds bit indicating single seconds marked by 15’s is located just above the VI.  The winding arbor is at an unusual position, located between III and IV.  The Fast/Slow adjustment is within the XII.  The pristine dial is encircled by a brass Roman ogee reflector ring.  It is housed in the thick glazed bezel which attaches to the case with a spring-loaded fit.  The all brass movement is a thing of beauty having a jeweled balance with numerous timing weights and a lever escapement.  The front plate is marked SETH THOMAS.  It also bears the Seth Thomas trademark of an ST within a diamond and a circle and it is signed “F. Hotchkiss.”  The case is of especially heavy solid bronze in classic ship’s clock form with flared bezel and mounting flange.  The dial measures 3 ½ inches in diameter.  The clock is 6 ½ inches in diameter and 2 ½ inches thick.   Outstanding cosmetic and functional condition in all respects.  The case has acquired a phenomenal age patina.  This model predates its Chelsea competitor by 10 years!  American ship’s clocks of this vintage routinely command thousands of dollars and porcelain dial ship’s clocks are particularly sought after.  Complete with period winding key.  879

In his landmark reference book “Military Timepieces,” 1992, American Watch makers Institute, author Marvin Whitney discusses this clock on page 143.  It is model number 5003 with a movement number of 208 dating 1883.  It is described as a “Chronometer Lever” running one day with a fitted jeweled balance and a tempered steel hairspring.

The Negus firm first appeared in the New York City directories at 84 Wall Street in 1850.  Thomas Stewart was trained as a chronometer maker in England and began working with his brother, John David in 1848, first under the name of Thos. S. Negus & Co.   During the Civil War the firm moved to 100 Wall Street and the name changed to T.S. & J.D. Negus.  The business of chronometer and navigational instrument making continued to grow, causing them to move to 69 Pearl Street in 1875.   From the Civil War onward, Negus enjoyed the patronage of the U.S. Navy as the suppliers of chronometers and other navigational equipment.  The firm was dissolved and sold to M. Low, New York in the early 1960’s.

This chronometer was manufactured by the venerable chronometer making firm of Thomas Mercer for A. Masselin, circa 1892, according to Tony Mercer, “Chronometer Makers of the World,” 1991, N.A.G. Press, Colchester, Essex, England.  Although Masselin’s number is very low, the number 5316 is stamped on the plates and matching number in the bowl, indicating Mercer’s production from 1892.  In the second half of the 19th century it was common for retailers to solicit the patronage of major wholesalers in the promotion of their products, with the retailer’s name on the product.

13.34  EARLY ENGLISH CHRONOMETER.  Important, extra fine English marine chronometer by the noted maker “Moncas Liverpool 9633” as beautifully engraved in flowing script on the silvered brass dial.  This highest quality navigational instrument exhibits several qualities indicative of its very old age.  The dial has bold Roman numerals and a minute chapter ring swept by solid gold hands.  The subsidiary seconds bit above the VI is divided in single seconds marked by 10’s.  The delicate hand of the seconds bit is scarcely thicker than a hair!  The unusually large and well-marked Up/Down indicator below the XII indicates 3 hour intervals marked by 6’s from 0 – 54, rather than the later standard 56.  It is also marked “UP, WIND, and 2 Days.”  It is swept by yet another solid gold spade hand matching the larger hands.  Telling of its early manufacture this chronometer has a beveled domed glass crystal with a thin knurled bezel.  The early form tub is square at the bottom with a spring-loaded winding dust cover.  It is slung in gimbals with an unusual, non-locking gimbal restraint and a matching brass holder for the winding key – both very early innovative features.  The diminutive all brass movement with beautifully blued screws has a bi-metallic balance with segmental pie-shaped weights typical of the 1820’s, blued helical hairspring, diamond end stone and of course a chain drive fusee.  Execution of all components is simply exquisite in every respect.  All of this is contained in its original brass-bound African mahogany box.  The figural wood was obviously chosen for its rich, dense nature, showcasing the box maker’s art at its finest.  Inlaid in the middle tier is the circular ivory number plaque reading “9633” matching the dial.  The top is inlaid with a brass shield, as is the key escutcheon on the front and typical brass drop handles on the sides.  A button latch secures the top lid.  Again, telling of its age, the hinges do not have stops, but open fully.  In addition, the lower section of the box has a felt dust barrier vs. the later form knife edge seal.  The chronometer itself is 3 7/8 inches in diameter.  The box is measures a very diminutive 6 inches square by 6 1/8 inches high.  A superb example of England’s finest output from the early 1800’s when chronometers were just starting to come available.  This is definitely museum quality.  5950  Special PackagingBack to Top

John Moncas was by no means a prolific maker.  He was much noted for his quality pocket watches.  Quite likely this was only the 33rd chronometer he ever produced.  In the early 1800’s makers were very aware of numbering their machines realizing that high numbers indicated tied and true machines.  To purchase “number 1” meant that the maker’s output had not yet been tested.  It made much more sense for the wary buyer to purchase number 9633 than to purchase number 33.

13.32  IMPORTANT CHRONOMETER.  Most desirable 2-day marine chronometer by one of England’s finest and most revered horologists.  This is John Edward Dent marine chronometer number 1590 as signed on the silvered brass dial “DENT LONDON 82 Strand No. 1590” and again on the porcelainized nameplate on the front of the box, “DENT 1590.”  The immaculate dial, unusually large for this type of configuration, features bold Roman numerals and a minute chapter swept by delicate blued steel hands.  The subsidiary second bit is below XII and indicates 0 – 56 hours with the unusual additional markings of “UP, WIND, 2 DAYS, and DOWN.”  It is protected by the early form domed glass crystal with thin brass bezel. The movement is housed in its gimbaled brass bowl with locking lever at the left rear and original ratcheted winding key, twice marked “1590,” on the right.  The magnificent all brass movement is a thing of beauty, with decoratively-spotted shiny brass plates, turned brass pillars, large bi-metallic balance with early form pie-shaped segmental timing weights, blued steel helical hairspring, diamond end stone in the balance cock, highly blued steel parts, spring détente escapement, and of course a chain drive fusee.  The inside of the bowl is stamped “DENT” and “1590.”  The exterior bottom of the bowl exhibits a very unique dust cover over the winding arbor.  It consists of a spring-loaded lever with cap covering the aperture.  This is a much more complex feature over the typical rotating disc found on virtually all other chronometers.  The simple crotch grain African mahogany box is indicative of early 1800’s chronometers.  It has folding drop handles on each side and an inlaid brass key escutcheon in addition to the previously mentioned maker’s plaque.  This extremely rare navigational timepiece measures a diminutive 6 ¼ inches cubed.  The unusually large dial measures 4 inches in diameter.  Absolutely outstanding condition in all respects.  It is a strong runner and is virtually perfect cosmetically.  Circa 1842.  Price Request Special PackagingBack to Top

Edward John Dent (1790-1853) was certainly one of the preeminent English horologers in the first half of the 1800’s.  During his very productive life he set up a large number of factories and workshops turning out his inventions and products.  According to Tony Mercer in “Chronometer Makers of the World,” Dent began his business career in 1814 at 64 the Strand and 28 Cockspur Street in London.  He moved to 84 the Strand in 1840.   In 1828 his chronometer No. 114 won the Premium Trails at Greenwich.  This fact caught the eye of pioneer chronometer maker John Roger Arnold who took Dent in as a partner in 1830.  The chronometer making partnership lasted 10 years.  Following their partnership Dent moved to 84 the Strand in 1840.  A number of Dent’s chronometers accompanied famous expeditions to both Polar regions and the tropics.   No. 1800 accompanied David Livingston during his African explorations.  In 1841 Dent was granted the Royal Warrant as “Chronometer Maker to the Queen and the Prince of Wales.“   Among his achievements beyond chronometer making, Dent was the maker of the famous “Big Ben” Parliamentary tower clock in London.  He designed and produced a very early form of aneroid barometer (without liquid) which revolutionized barometers at sea.  He also invented and produced his patented depleioscope which used the sun’s rays to determine local apparent noon for the purpose of accurately setting of watches.

In his monumental biography of E. J. Dent, Vaudrey Mercer, author of “Edward John Dent and His Successors,” 1977, The Antiquarian Horological Society, Church Hill, Ramsgate, England  indicates Dent Marine Chronometer No. 1581 as dating 1841.  Then bracketing Dent Marine Chronometer No. 1600 is dated at 1842.

13.62  IMPORTANT CHRONOMETER.   Most rare navigational timepiece made  by the  pioneer English makers at the time when chronometer making was still in its infancy.  This incredible 2-day example was made by the venerable partnership of William Parkinson and William James Frodsham, begun in 1801 and actually dates to only a year later – 1802!  The diminutive navigational timekeeper has a silvered brass dial beautifully hand-engraved with the makers’ signatures “Parkinson & Frodsham Change Alley London 122” amidst flourishes.  The dial has bold Roman numerals and a minute chapter marked in 5 minute intervals swept by blued steel spade hands.  A subsidiary seconds bit is above the VI position with a fine blued steel needle hand.   Indicative of its early origin, it has no Up/Down indicator – a feature which came some 20 years later on chronometers produced by these makers. The dial is protected by its classic early form convex crystal.  The squared tub with rotating dust cover on the bottom is slung in gimbals in its unusually small box with gimbal lock and ratcheted winding key.   The movement is housed in Frodsham’s “signature” inner dust cover.  It is absolutely a thing of beauty with its diamond end stone,  blued steel helical hairspring, large compensated balance with early-form segmental pie-shaped weights and beautifully engraved brass top plate with the signature “Parkinson & Frodsham, Change Alley, London, No. 122.”  The exceptionally small plain mahogany box, indicative of this early period, has all brass furniture and is complete with its original box skeleton key and old style folding brass drop handles.  Telling of its early origins it has a felt-lined dust strip surrounding the precious mechanism.  The front of the chronometer box is inlaid with the matching ivory nameplate “122.”  5 ¼ inches square and only 5 ½ inches high – smaller than most deck watches!  Lovely original condition.  The movement has just been thoroughly serviced in England by a former employee of the Mercer Company of chronometer fame and is guaranteed to be in tip top running condition.  The box and all components are original.  An amazing surviving relic from the early days of sail, worthy of the finest museum!

Interestingly, an Internet competitor sold a similar clock a few years ago, for a very large, but undisclosed sum of money.  Their write-up goes to great lengths to extol the superb quality and rarity of that clock, which was clearly not as nice nor as old as the example offered here!  What’s more, we are now offering this same type clock for a much lower price than the inferior example sold for several years ago!  The link is:  http://landandseacollection.com/id191.html

Brock and Company was a prominent, nationally recognized jewelry firm, certainly the most important jewelry store in Los Angeles. Brock's was founded by George A. Brock in 1903. In growing the company, Mr. Brock merged a number of other established Los Angeles jewelers into Brock & Company, including S. Nordlinger & Son, which had operated in Los Angeles since the late 1800's. In the 1920's, George Brock obtained a 99-year ground lease on the property at 515 West Seventh Street, and soon the custom-designed structure (now housing Seven Grand) was built.

With son George C. Brock at the helm, the company continued to grow. A second store was opened on Wilshire Boulevard, in Beverly Hills. At that time Tiffany and Co. even proposed the merger with Brock of "Tiffany-Brock & Co." However Brock's valued their independence and the merger did not take place.

In the early 60's, George C. Brock decided to retire. Ben Weingart, a young real estate broker in the 1920s, had been involved in the 99-year ground lease for the Brock & Co. parcel on Seventh Street. He approached Brock about purchasing some land owned by the company. Mr. Brock told Weingart that the only way he could acquire the land was to buy the company.

Mr. Weingart did just that, purchasing the single remaining Brock & Co. store downtown in 1964. Thereafter Mr. Weingart brought in a liquidator who operated the business for a few years, gradually selling off its inventory. The jewelry business ended, and some of the store fixtures were sold. Clifton's rented the building installed a cafeteria. George C. Brock died in 1967.

Originally offered as the “Yacht Wheel Clock with Base” in 1906, Chelsea gave this configuration its own identity as the “Mariner” in 1928.  The model was ultimately discontinued in 1984.
