A good example of this unusual Powell's Patent movement, circa 1870
Three-quarter plate movement with the mainspring set into the pillar-plate, only the great wheel and maintaining power ratchet visible between the plates - see pic. Single-roller detached lever escapement with single-pin banking via a hole in the tail of the lever. Compensation balance, spiral balance-spring. Numbered enamel dial. 45 mm diameter, 9 mm deep, not including centre arbor.
Charles Powell, Birmingham 'Watch Manufacturer' Patent No 3144, November 1862, in which the mainspring is separated from the arbor and great wheel which is fitted with maintaining power. These movements, all of the same caliper and with the same lever escapement, are known with a variety of retailers names.
Hair crack in dial and lacking hands, otherwise in very good original condition. Not cleaned by me but will tick when wound.
