More details

Slim half-plate keyless going-barrel movement (openface set) jewelled to the centre, with cap jewels on balance (diamond), lever and escape, the frame stamped with NN's number. Single-roller detached lever escapement. Compensation balance, balance-spring with double overcoil. Beautiful snap-on enamel dial with tumbling Arabic hour numerals in perfect condition, fully signed for Dent along with their triangle trademark, the rear signed by its maker WILLIS, original blued-steel hands. 49 mm diameter, only 9 mm deep.

The firm of E Dent & Co, then at 61 Strand and 4 Royal Exchange, one of the leading London watch, chronometer and clock makers of the period - see the book on Edward John Dent and the various Dent firms by Vaudrey Mercer. This unusual caliper of movement and dial by Nicole Nielsen, their largest size, was usually fitted into their dog-collar cases - see my reprint of their High Class English Watches catalogue, Type 16.

All in very good original condition with nothing broken, but the safety pin appears to be rubbing on the roller so the action stalls. Not cleaned by me and sold needing at least adjustment to work properly.
