ABSTRACT:
A wristwatch movement has a back cover formed with a battery replacement hole, and a base plate formed with a battery compartment in a substantially axial alignment with the battery replacement hole. An actuating lever has one end selectively engageable with a setting lever engaging with a winding stem extending through a radial bore of the base plate, and another end formed with a handling portion extending toward the battery compartment such that the handling portion can be manipulated through the battery replacement hole to cause the one end of the setting lever to disengage from the winding stem, to allow the winding stem to be pulled out of the radial bore.
