Abstract
In a generatorin an electronic-controlled mechanical timepiece, the winding coreof a coilarranged nearer to the perimeter of a base plateis made shorter than the winding coreof a coilarranged more inside. Accordingly, it is possible to make the area of an openingcan 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 plateas keeping the distance Dbetween the corner part of the openingand the perimeter of the base plateto the same degree as the prior art and thereby securing the strength of the base plate
