Astronomical chronometer
Astronomical chronometer. Thomas Earnshaw made this watch for George Margetts to Margett's design of complex astronomical dialling, but incorporating Earnshaw's spring detent escapement invention. These early chronometers by Earnshaw were usually marked with a stamp and serial number, to denote that a fee was paid to Thomas Wright, who funded Earnshaw's patent costs.
