Abstract: In a generator 120 in an electronic-controlled mechanical timepiece, the winding core 133b of a coil 134 arranged nearer to the perimeter of a base plate 2 is made shorter than the winding core 123b of a coil 124 arranged more inside. Accordingly, it is possible to make the area of an opening 2c can be made smaller in comparison with the prior art, and make the timepiece more small-sized by making smaller the outer diameter of the base plate 2 as keeping the distance D1 between the corner part of the opening 2c and the perimeter of the base plate 2 to the same degree as the prior art and thereby securing the strength of the base plate 2.

Abstract: To effectively prevent positional deviation of a battery. A hook-shaped member of a spring electrode terminal, and hook-shaped members of a spring electrode terminal are arranged in respective apices of a regular triangle to restrict movements of a battery in a direction along a cross section against the bias of a spring electrode terminal, which abuts against a negative surface of the battery. Battery abutments are arranged in respective apices of a substantially regular triangle to permit the bias of the respective spring electrode terminals to bias the battery toward the battery abutment, thus restricting positional deviation of the battery in a horizontal plane. When the battery is to be removed, a battery removal tool arranged near the hook-shaped member is inserted into a tool insertion portion to remove the battery.

When the user cannot wear the watch it is proposed to place it on an automatic re-winding device. The device according to the invention is compact and modular. Furthermore, in order to avoid any error of manipulation, the starting and stopping of the re-winding device is done automatically by means of a detection of the presence of the watch (3). The passing of the strap in the detachable base (2) produces the tension of the device.
