A ship’s chronometer; this model 21 style chronometer was originally developed for the U.S. Navy by the Hamilton Watch Company
of Lancaster, Pennsylvania.This lovely state-of-the-art instrument (for its era) features a full size ship\'s chronometer with silvered dial,
56 hour UP/DOWN indicator, black steel spade hands with luminous tips, bold Arabic numerals, and a subsidiary seconds bit. The
dial is signed \"HAMILTON, LANCASTER, PA, U.S.A., U.S., 2E12336\". The high grade movement is a work of art, with highly finished
damascened nickel plated brass plates, large innovative Elivar-metallic balance, detente escapement, and a chain drive fusee. The movement
bears the matching signature \"Model 21, 14 Jewels, Hamilton Watch Co. Lancaster, Penna., Made In U.S.A., SP.97, 2E12336\" The
movement is fitted into a solid brass housing and accessed through a screw on brass bezel with silvered beauty ring and a beveled glass.
The entire housing is mounted to gimbals within the box, and equipped with a knurled gimbals lock at the right front. The box is made of rich
mahogany in a natural finish with brass box corners which have lost there finish and are tarnished. All the fittings are of solid brass
including the box stays, button latches, folding drop handles, hinges, and inlaid brass dust rail, they all have some amount of loss to the
original finish and are tarnished. The inside bottom rear of the box has the original brass maker\'s label reading \"HAMILTON WATCH CO.
Lancaster, PA., U.S.A.” and a similar label is mounted to the upper front of the 2nd tier cover, only the material used is a white plastic.
The observation lid and all of its mounting components are MISSING (NOT included); as were most lids on boxes that were actually
used on ships. In my humble opinion the box and chronometer are NOT a matching set as there is no tarnish on the chronometer housing
and quite a bit on the gimbals assembly which resides in close proximity.
This chronometer is from an estate and is not running, I am not very knowledgeable about this chronometer escapement but noticed when
I removed the movement to take pictures that the balance was resting on its side and leaning onto the plate (not a good thing). There is some
scuffing to the plate where the balance has rubbed against it. I removed the cap/end jewel cover by removing the 2 small screws and below
it there was a 1/8\" diameter (approx.) hole in the steel bridge, with NO upper jewel or gold jewel setting as I presume should be there. Under
magnification the upper end of the staff appears to be in a conical shape. I do not know what a \'perfect staff looks like so I can not say
whether there is any damage to the staff. I did lift the staff while it was in place and the top end of the staff looks very similar to the bottom
end. The bottom end of the staff feels as though it is \'secure\'; but I did not disassemble any of the rest of this escapement to visually look
at it or its jewel; I will leave that to an \'expert\'. The other movement parts look exceptionally clean. I am selling this clock
\"AS IS / IN NEED OF REPAIR\", with no implied guarantee or warranty. Please see the 12 detailed pictures for condition,
the last picture shows the bridge with the cap/end jewel removed. The box has several scratches (some deep), dents and scrapes,
but still maintains a nice patina. The wooden base is missing all of the green felt. All in all, a beautiful movement, inside and out.
There is one small dent (approx. 1/8\" diameter to the side of the brass movement housing.
The box measures 7-9/16\" x 7-9/16\" x 6-3/4\" and weigh in at 8 pounds and 13 ounces. NO key included.An outstanding nautical timepiece that would look as great on a Yacht as in a study or on a living room table!Please ask any questions before you offer. Thank You for looking and May God Bless.

The clock I am selling has 2 threaded posts with knurled nuts mounted to the outside of the brass movement housing. One of the posts is
insulated from the brass housing with a plastic spacer. There are also some additional parts attached to the movement. A member of the NAWCC
(National Association of Watch and Clock Collectors) sent me this REFERENCE INFORMATION about a SIMILAR, BUT NOT THE SAME
clock to show what those \'additional parts\' on the movement can be used for; I thought this would be useful information to whomever purchases this clock. The article read as follows:\"This chronometer is most likely one of 5 that Hamilton produced in 1955 for the Seismic Laboratory of the California Institute of Technology*.
The serial number of this example is 2E11659. It is based on the model 21 but has additional mechanisms for both minute and hour break circuits.
The pieces were used to improve correlation between seismometers at distant locations and therefore improve the ability to localize the seismic event.The circuits are implemented with modified spring detents made from the standard ones used for timekeeping. Each of these is jeweled, so the
actual jeweling on the selective break circuit chronometers is 16 jewels. Hamilton produced chronometers with a single break circuit starting in
1945. In 1956 they had produced 201 single break and 5 selective break chronometers (more may have been produced later).*Historical information on the chronometer is from Marvin Whitney\'s book Military Timepieces published by the AWI Press in 1992.\"The gentleman also stated that the radium markers are an \"unusual\" feature and that the clock in the article 2E11659 is a little earlier serial number (than the one listed) and was sold to Cal Tech in 1955 and he stated \"Your serial number is after the last recorded sale at 2E12330.\"Just thought I would pass on this information, thank you again for looking and if you have any questions please ask.
