S SACKS, Huddersfield. No 1063
Very rare example of a Coventry ‘PATENT’ watch with Vale & Rotherham’s detached lever escapement.
£2,995.00
Gold engine-turned case with chased ‘floral’ band, pendant and bow hallmarked Chester 1818, casemaker HH (Hannah Howard, Liverpool). Capped fullplate fusee movement with index on the table of the cock and the foot engraved PATENT, the cock foot and cap both stamped D. Detached lever escapement of a type that is rarely encountered, the lever with upstanding fork and a double height roller incorporating both safety and unlocking, all in steel. Steel balance, spiral balance-spring. Engine-turned and matted gold dial in lovely condition, blued-steel serpentine hands. 47 mm diameter and weighing just over 115 grams gross.
S Sacks, Huddersfield, retailer, known to have also sold watches with Massey’s escapement.
Thomas Mudge did not patent his detached lever escapement and those few (Emery, Grant, Pendleton, etc) in the late 18th century who used his escapement did not either. This changed in 1812 when Edward Massey took out the first of his patents covering the detached lever. This led to a number of other escapement makers devising their own version, primarily I believe, in order to avoid infringing the patent. One of these, the ‘single’ or ‘table’ roller lever was eventually to become the standard English lever escapement, but others were also tried, with various levels of success. This escapement was, I believe, first used in watches by Vale & Rotherham, this being a particularly early example – my drawing of this escapement is from a watch retailed by Vale & Rotherham
Some wear to the light engine-turning on the case and thinning of bow, otherwise in good original condition, especially the crisp dial. Serviced and guaranteed.
