Abstract

488,979. Watches. COLOMB, H., and TAVANNES WATCH CO. SOC. ANON. Nov. 29, 1937, No. 32952. Convention date, Feb. 3. [Class 139] The winding mechanism of a watch comprises a crown 4, secured fast to the stem 5, with a hollow 3 in which extends a pendant sleeve 2 rigid with the casing 1. A socket 6 with a flange 7 slides over the sleeve 2. A ring 8 forced in the hollow 3 prevents axial relative movement between the crown 4 and socket 6 and permits transversal relative movement.
