American Hamilton Model 21 Marine Chronometer

Since its invention in 1761 by John Harrison of England, the marine chronometer has been used for navigational purposes.  Its precision and reliability for accuracy to within seconds is truly remarkable.  As a result, many marine vessels were kept safe and on course for hundreds of years.

This Hamilton chronometer has a 14 jewel chain fusee driven movement with chronometer detent escapement.  It also features a poised balance wheel and maintains a 56 hour power reserve.  It has an engraved silvered dial with Arabic numerals, seconds dial, and winding status indicator.  Additionally the dial is signed “Hamilton, Lancaster, PA.; U.S. Maritime Commission” with a serial number 2E12153.

The chronometer is in a mahogany gimbaled case with winding key and comes with a one year warranty.
