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

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.

The dial with just a minor edge flake near 12, otherwise complete and unbroken. Not cleaned by me and tries to tick when wound, but sold as needing at least a service and fresh oil to work properly.
