Abstract

929,566. Clocks and watches. FABRIQUES MOVADO. Nov. 16, 1959 [Nov. 21, 1958], No. 38695/59. Class 139. A timepiece mechanical oscillator comprises a body 1 supported by three leaf-springs 3 fixed at their ends to the body and to a frame plate 2 by sector-shaped wedge members 4 forced into a hole in the body and plate. The body is maintained in circular oscillation by the co-operation between a multipolar magnet carried thereby and a coil. A ferromagnetic ring is supported by the magnet and by machining the ring or interchanging it with other rings frequency adjustment may be obtained. Two similar mechanical oscillators may be used.
