Pride of the Vacheron Constantin Heritage, built in 1755, this venerable pocket watch’s silver case bears the engraved inscription “J: MC: Vacheron A GENEVE”. Secured directly to the case, its movement with crown wheel, fusee and chain measures
35.60 mm across. It is key-wound between 3 and 4 o’clock on the enamelled dial side after lifting the hinged bezel and its watch glass.
