Rare Swiss early 1930's twin Patent automatic centre-seconds wristwatch.
Stainless-steel case with screw on back marked *Acier* STAYBRIGHT, numbered 18321, the crown only allowing hand setting. Nickel plated movement over which is mounted the 'bumper' automatic unit in the form of a ring shaped module, the outer ring engraved with the Swiss Patent numbers 149,137 and 149,138. Detached lever escapement with steel club-tooth escape. Compensation balance, spiral balance-spring. Silvered dial with original luminous filled blued-steel hands and matching hour figures. 30.5 mm diameter.
Glycine Watch Co. Bienne, Switzerland, a company founded by Eugene Meylan in 1914. With increasing sales of watches into the English speaking market, the firm produced their own automatic movement in 1931, a module fitted to their standard hand wound movements. This followed on from the earlier work and Patents of John Harwood; Glycine, along with Rolex, being among the earliest in the field. The firm took out two Patents covering their work but, like Harwood, the depression of the early 30's meant that sales and thus production was limited. As far as I am aware, examples are rare, especially in this condition.
Some age spotting to dial and the minute hand slightly misshapen (this appears worse in my images than it is in real life, especially when on the wrist), but still retaining the original luminous compound with almost no loss. The s-steel case in good clean condition and fitted with suitable new/old stock tan leather strap. Not cleaned by me but will tick happily if worn, but sold as probably needing a service in order to run correctly.
