Rare Morton's Patent-type movement, circa 1861.

More details

Three-quarter plate, hollow back fusee movement jewelled to the 4th, but with no jewel on the lever, as usual, the 16-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 2626, gilt hands. 44.5 mm, 8.5 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 hair minor cracks, lacking impulse jewel and all rather dusty. Otherwise complete and in good condition. Not working but looks to be entirely repairable, and it retains its rare escapement not having been changed, as many have.
