Large barrel-edge silver case hallmarked London 1820, casemaker CL (Charles Lupton, Clerkenwell). Fullplate fusee movement with cap jewels on balance (diamond) and escape, with rim cap and unusual balance-bridge, the latter pierced in the style originally associated with Larcum Kendall and often used by Vulliamy. Cylinder (dead beat) escapement with brass escape. Steel balance, spiral balance-spring. Unusual engine-turned and matted silver dial with applied gold numerals and large seconds intersecting the chapter ring, gold hands. 56 mm diameter.
William, son of John Holmes, and who continued the business in the Strand, London – makers of fine clocks and watches.
NB: It is unusual to find a caliper of movement of which no other example is known to exist, and this watch fits the bill. The dial is also most unusual with its combination of a larger than normal seconds, plus the mechanical engine-turning mixed with the outer hand done matting. It is also almost impossible to photograph in a way that does it justice. I have tried, but failed I think, and the watch is much better in the hand.
A large and well made watch, and probably unique. Case dial and movement in good original condition showing few signs of use. Serviced, guaranteed and supplied with a correctly fitting key if required.
