Rare Morton's Patent-type movement, circa 1863.
Three-quarter plate, hollow back fusee movement jewelled to the 4th, but with no jewels on the lever arbor, as usual, the 14-size frame stamped, also as usual, HF (probably Henry Fletcher, Prescot). London Patent Robin-type escapement with lever-type escape and unlocking and chronometer-style impulse in one direction only, via a radial set jewel in the roller, banking is via a flat on the balance-staff. Compensation balance, spiral balance-spring. Enamel dial signed CHRONOMETER 2017, gilt hand. 43 mm, 8 mm deep, not including centre arbor.
London Patent Chronometer escapement, a development of George Morton's original Patent No 2434, October 1857. As development took place the watches are variously engraved, if at all: Morton's Patent; Morton's Patent Improved; Patent Chronometer; London Patent Chronometer; and finally Patent Union Chronometer, all numbered within the same sequence. See my recent Horological Profile on these Morton's Patent watches for full details.
Dial with faint hair crack at 6 and lacking minute hand, otherwise complete and in good but dirty condition. Will tick if extra pressure is applied to the train but sold as needing at least cleaning and fresh oil to work properly.
