ABSTRACT:
An apparatus for correcting a timepiece display includes a winding stem which extends within the timepiece and without the timepiece. The winding stem is movable from a normal carrying position to a first changing position. A convex region is formed on the winding stem. A sliding pinion is mounted about the stem. A first calendar correction operating wheel is loosely fit about the stem in the normal carrying position. The convex portion of the stem engages the first calendar correction operating wheel to provide a friction fit when the outside operating member is in the first step changing position to conduct date correction.
