Thomas Russell & Son, one of the largest and most famous Liverpool watchmakers of the period, and the only manufacturers of watches with S J Morgan’s patents.

S J Morgan, PATENT No 20,134, October 1899. Winding indication for going-barrel watches (much harder to achieve than with a fusee) incorporating differential gearing using a tangential pinion running within a slot in the pillar plate. NB. Russell produced two forms of this Patent, this being their best quality example with lovely sector up/down.

Lacking c-secs and state-of-wind hands, the dial with just a minor chip near 6, and rather dirty. Otherwise complete and an unusually large size. Not cleaned by me but will tick when wound.
