FIELD: electronic engineering. SUBSTANCE: clock-work has ping-motor with rotor and stator, which is made like plate with apparent poles. Rotor seat is made in stator plate between poles. Rotor is connected kinematically to hand of clock axes by wheel-drive fitted at board through live axles bearings. Board is arranged at one plane with plate and they are jointed tightly at least a part of plate side surface contiguous to side surface of stator plate. Board is made from magnetically permeable material and its construction permits to reduce watch total thickness keeping high technical data. EFFECT: reduced watch dimension. 3 cl, 3 dwg
