Slim movement with very rare if not unique chronometer escapement, circa 1855.

More details

Slim three-quarter plate fusee movement jewelled to the 3rd, with cap jewels on balance (diamond) and escape), the 8-size hollow-back frame stamped A&G. Earnshaw-type of chronometer escapement but the spring-detent with side facing foot attached to a lyre shaped steel support, the polished steel roller slotted to allow the detent to be placed into its position 'above' the roller, as necessitated in such an unusually slim frame. Compensation balance, 7-turn blued-steel helical balance-spring. 37 mm diameter, only 5 mm deep, not including centre arbor or dial.

George Edward Frodsham and almost certainly the chronometer maker Walter Baker, a partnership that saw some interesting clocks, watches and chronometers being produced prior to Baker leaving the partnership in 1863.


A&G: Abbott & Garnett, Farnworth near Prescot, Lancashire, recorded as 'watchmakers' in Trade Directories of the 1834-1851 period, manufacturers of top quality rough movements, often of great individuality.


A fine movement with a most interesting and un usual escapement. Lacking dial, motion work and hands, and rather dusty. Despite not being cleaned, it will run happily when wound.
