Abstract

The movement of the electronic watch includes wheelwork which is actuated by the rotor (6) arranged between the poles of the stators (7 and 8) and actuated in stepper fashion. The central seconds runner (12) includes toothing which meshes with the toothing (11a) of the runner (11). The module of these toothings is chosen between 0.025 and 0.05 mm. It is smaller than the module of the other elements of the wheelwork. The number of teeth in the seconds wheel is 45. <IMAGE>
