MARTIN. Royal Exchange, London. No 2489

96201

Rare cylinder movement by this little known maker, circa 1785.

More details

Well finished fullplate fusee movement with balance-brake, Harrison's going-fusee, jewelled to the 4th with cap jewels on balance and escape, both cap and movement signed. Cylinder (dead-beat) escapement, with 16-tooth brass escape. Steel balance, spiral balance-spring. 38.5 mm diameter.

Thomas Martin watch and chronometer maker, Cornhill and later at the Royal Exchange, London, made Liveryman of the Clockmakers' Company in 1780. Thomas Earnshaw mentions him as a good maker.


NB: Following on from the success of John Harrison's H4, maintaining power was gradually introduced into London watchmaking, but only slowly. Very few watches of this date are known to have a going-fusee, and the extent of jeweling in this cylinder watch is also unusual for the time, mostly being used for the earliest pocket chronometers at this period. 


Lacking brass-edge motion-work etc, otherwise complete. Not cleaned by me but will tick when wound.
