More details

Silver case hallmarked London 1862, casemaker R.O (Richard Oliver, 19 Galway St, St Luke's, London). Unusual capped movement in which the 4th, escape and lever arbors are pivoted under a single separate bridge, with the rest of the train, the balance, balance-cock and its potence attached to what is in effect a half-plate, the 16-size frame stamped ES (Edward Scarisbrick) and PF (probably Peter Forber). single-roller detached lever escapement. Steel balance, spiral balance-spring. Cream enamel dial signed PATENT, blued-steel hands. 50 mm diameter.

Edward Scarisbrick "watch movement maker," working in Atherton St, Prescot at this time.

Peter Forber "watch frame maker" living next door to Edward Scarisbrick, at 37 Eccleston St. By 1871 Forber's occupation is given as a "grocer" so he was one of many who succumbed to the decline in Lancashire watchmaking forced by the rise of watchmaking in America. Thank you Keith for this information.

I cannot find this caliper in the Patents as published but it may be a development of that taken out by the London watch manufacturer Henry Webster of Dalby Terrace, City Road, in September 1855. That patent, No 2042, allowed for the separation of the escapement in its own sub frame such that the different watchmaking trades involved could work on the same frame at the same time. This may (or may not) be the reason for this strange caliper, but the case is numbered as the movement, which, given its high number, would indicate an established watch manufacturing firm, such as Webster.

Case showing wear and the usual hair crack into the drilled seconds bit in the dial, which I believe to be quite a normal occurrence at the time of manufacture. Otherwise an unusual watch that needs further research. Serviced and guaranteed.
