Silver engine-turned case hallmarked London 1839, casemaker SS (Samuel Saltmarsh, Clerkenwell). Fullplate fusee movement with jeweling on the balance and the 4th wheel but not the lever or escape, an unusual combination. Once with Philcox’s ‘diamond lever’ escapement but now converted to a single-roller detached lever. Steel balance, spiral balance-spring. One-piece signed enamel dial with offset seconds, mismatched gilt hands. 44 mm diameter.
George Philcox, Southwark Square moving to Wellington St, London Bridge at this period. Patent No 8145, July 1839, the “diamond lever” escapement, involving a most unusual pallet and escape wheel, of which I can find no surviving example. This watch was once owned by Ken Shanks and is mentioned in a Letter by him published in Antiquarian Horology, Spring 1978 issue, page 741. Shanks asks the question if any members know of another example, to which I believe he received no reply.
Case rubbed, hair cracks to dial, mismatched hands and the escapement changed. That said, it is possibly the only surviving example and one that could, in expert hands, be restored. Not cleaned by me and not working – priced accordingly.
