Rare example of Keys Patent keyless fusee work, circa 1870.
Three-quarter plate fusee movement jewelled to the 3rd, with hard brass setting on the fusee, the Lancashire supplied rough movement stamped by JW (Wycherley) and by Keys, with his unusual keyless fusee work. Single-roller detached lever escapement. Compensation balance, spiral balance-spring. Lovely, and then unusual, 'Roman & Arabic' dial, blued-steel hands. 43 mm diameter, 7.5 mm deep, not including centre arbor.
Patent No 2330, September 1865 "Improvements in watches, and in the method of and apparatus for winding up fusee watches..." David Keys & Son 'Chronometer & Watch Manufacturers' 15 Craven St, Strand, later with a retail shop in Piccadilly, an important but now little know London firm who supplied many fine and interesting watches to numerous retailers - it is somewhat unusual to see a watch bearing their own name.
Dial with hair cracks, sadly, otherwise in good original condition. Not cleaned by me but will tick if wound.
