A fine, completely original Model 21 World War II chronometer developed for the U.S. Navy by the Hamilton Watch Company of Lancaster, Pennsylvania. This exceptional time instrument features a full size ship's chronometer with silvered dial, 56 hour UP/DOWN indicator, blued steel spade hands, Arabic numerals, and subsidiary seconds bit. The dial is signed "HAMILTON, LANCASTER, PA, U.S.A. and N7367-1941 in the center of the second hand." The movement bears the matching signature "Model 21, 14 Jewels, Hamilton Watch Co. Lancaster, Penna, Made In U.S.A. 2E7367." All of this is fitted into the solid brass "tub" suspended in a gimbaled ring mounted within the box, equipped with a gimbal lock. The brass-bound box is the traditional 3-tier type made of mahogany and survives with the original lacquered finish and solid brass fittings. The chronometer has the addition of a balance lock, a feature added later by the US Navy. The front of the box bears the original maker's label reading "HAMILTON WATCH CO. Lancaster, PA., U.S.A.". This fine chronometer survives in like-new condition inside and out, with only a few minor surface scratches on the mahogany box. It is completely functional and comes with its original ratcheted Hamilton winding key.
*The Hamilton Watch Company produced 8900 chronometers in total for the US Navy.
