A starter which applies a mechanical rotating force to a rotor of an electromagnetic converter, such as a power generator, for startup of the rotor. The starter includes a startup spring (60) having an engaging portion (63) engageable with a 6th pinion (11a) of a wheel train coupled to the power generator. In interlock with the operation of pulling out a crown, a reset lever (70) is operated to bias the startup spring for engagement with the 6th pinion.
