Abstract

875,427. Watches. OBERGFELL, R, and OBERGFELL, H., [trading as KIENINGER & OBERGFELL]. Jan. 6,1958 [Feb. 5, 1957], No. 458/58. Class 139 An electric watch has a secondary battery which is charged by the current induced in a pair of coils 4, 5 by the relative movement between the coils and a freely pivoted permanent magnet inertia mass 3. Additional pairs of coils may be disposed round the periphery of the watch casing. A half or full-wave rectifier is located between the coils and the battery.
