Rare and very early complete example of Morton's Patent escapement.
Silver barrel-edge case with fixed dome, hallmarked Chester 1857, casemaker, RS (Ralph Samuel, Wood St, Liverpool). Capped fullplate fusee movement also engraved 'Morton's Patent.' Morton's Patent detached escapement with the 'improved' form of roller and safety action (the earliest known), with standard ratchet-tooth escape. Compensation balance, spiral balance spring. Signed cream enamel dial with CHRONOMETER in red and numbered 370 (a dial painter's mistake), blued-steel fleur-de-lys hands. 51 mm diameter.

George Morton, Market Place, Keighley, Yorshire, Patent No 2432, October 1857, a Robin-type detached escapement with chronometer style (single) impulse. As subsequent development took place the watches are variously engraved, if at all: Morton's Patent; Mortons Patent Improved; Patent Chronometer; London Patent Chronometer; and finally Patent Union Chronometer, all numbered within the same sequence, the last known number being just over 3000 - No 575 is a particularly early survivor, being the third earliest complete watch so far recorded. See also my Horological Profile No 1 for the best and most up to date information - copies available on my website.
Dial with chip (at 12) and faint hair crack, plus the light engine-turning to the case now mostly worn smooth. Otherwise complete and working well, but not serviced by me and priced accordingly.
