Early key wound 'machine-made' movement by this important English manufacturer, circa 1890.
Capped fullplate going-barrel movement, the hollow-back frame numbered and stamped R&S (Rotherham & Son) as well with their trademark, the cap stamped SPICER. Single-roller detached lever escapement. Gold balance, spiral balance-spring with unusual and distinctive stud. Signed enamel dial with their trademark plus the letters 'G B.' 41 mm diameter, 10 mm deep, not including centre arbor.
Vale & Rotherham, later Rotherhams, one of the most important English (Coventry based) watch manufacturers and one of the first to bring American 'machine-made' manufacture to England on machinery obtained from the Waltham Watch Company. This is the only example of its type I remember having seen with 'G B' on the dial, which I presume stands for Great Britain and was perhaps only used on export models. It also bears an unusually low number, possibly because a new number sequence was started when they began their American-style production - this ran alongside their standard production for many years.
NB: I have only noted the cap makers name SPICER on Rotherham & Son movements.
Hair cracks to dial and lacking hands, otherwise in good original and unbroken condition. Not cleaned by me and too dirty to tick properly. Sold as needing at least a service and fresh oil to run properly.
