Abstract
PURPOSE:To increase the working ability by making easy the positioning, by mounting the step motor in thin unit and the thin circuit board fitted with electronic components with duplication into the watch case. CONSTITUTION:The step motor 15 consists of the rotor 15a including the permanent magnet of 60 poles, stator 15b opposingly located at the external of it, and coil 15c wound with a plurality of turns along the circumference direction at its external, and they are contained in the motor case 15d having almost equal external diameter as the inner diameter 11a of the watch case 11 to constitute the thin unit. Thus, almost the components mounted in the case 11 such as circuit board fitted with the electronic components can be duplicated with the motor unit as the thin plate unit having almost the same diameter as the inner diameter of the case 11. Accordingly, the positioning is made easy and the working ability of assembling can be increased.
