ABSTRACT:
A timepiece hand adjustment mechanism especially for small wristwatches comprises a control shaft with a squared key structure formed thereon and a coupling lever operating member with squared central passage disposed on the key structure so as to be movable therewith. The coupling lever operating member has a collar of which a section projects into an elongated opening in a coupling operating lever so that the lever can be pivoted by axial movement of the control shaft for coupling the adjustment mechanism while, at the same time, it can be rotated for adjusting the hand position.
