Thomas Mercer Ltd., St. Albans, England

, Movement No. 790, 255 mm, circa 1967

A ship's wall clock with 8 day movement, power reserve indicator and spring detent escapement


Case: brass. Dial: silvered. Movm.: brass movement, chain/fusee, spring detent escapement according to Thomas Earnshaw, seconds contact device, hack feature, bimetallic chronometer balance with 2 screws and 2 weights.

This wall clock with seconds contact was most likely used as a master clock. The top-quality movement with eight day power reserve, the detached escapement and the dial are all marked with the number 790. The constant second mechanism is ingenious: As this is a wall clock without a pendulum, the clock cannot be restarted simply by a turn of the balance (same as with a ships’ chronometer); instead, a mechanism consisting of several gearwheels transmits an impulse to the balance when a slide on the dial is pushed.
