Three-quarter plate keyless going-barrel movement jewelled to the 3rd with cap jewels on balance and escape, the top plate with raised barrel and bearing the firm’s ‘time-ball’ trademark, the 14-size frame stamped with Fridlander’s serial number and J.H.B, a rarely seen rough movement maker. Single-roller detached lever escapement. Compensation balance, spiral balance-spring. Signed enamel dial, blued-steel hour hand. 43 mm diameter, 10 mm deep, not including centre arbor.
Samuel Smith & Sons ‘Watchmakers to the Admiralty’ London, one of the largest retailers of English and Swiss made precision and technical pocket watches of the period. See Smiths Guide to the Purchase of a Watch for further information about this caliber. This movement is a Class 92, the number of which is 459.
The longer second number is that of Alfred Fridlander one of Coventry’s best and most successful watchmakers, a main supplier to Smith & Son.
Lacking minute and seconds hands, the dial with a small edge chip and all rather dusty having been stored for many years. Otherwise complete and nothing appears to be broken. Not cleaned by me and tries to tick when wound, but sold as needing at least a service and fresh oil to work correctly.
