(57) [Summary] [Objective] The efficiency of conversion of mechanical energy into electrical energy is improved by reducing the hysteresis loss of the generator, and an electronically controlled MECA watch with a long duration is realized. [Structure] The rotation of the mainspring 1a housed in the barrel wheel 1 is transmitted to the rotor 12 via the second wheel 7 to the sixth wheel 11 constituting the train wheel. Here, the generator (rotor 1 2, a stator 15, a coil block 16 and the like) forming a magnetic circuit of a stator body 15a and a magnetic core 16a, It is characterized in that the coercive force after magnetization of 10 (Oe) is 0.05 (Oe) or less. |
