Abstract

736,737. Electric timepieces. LIP SOC. ANON. D'HORLOGERIE. July 9, 1953 [July 9, 1952], No. 19115/53. Class 139. A timepiece has a balance I controlled by a hair spring Fig. 1, and electromagnetically impulsed by an electromagnet 4, 5. A permanent magnet 8 of one or several pieces and having a central pole rotates with the balance and co-acts with a similar stationary permanent magnet 10 to neutralize the disturbing torque due to remanence or polarization of the electromagnetic maintaining circuit.
