ABSTRACT:
A click mechanism for a timepiece winding stem comprises a plurality of circumferential grooves axially spaced along the length of the winding stem, and a detent spring resiliently engageable within respective ones of the grooves to retain the winding stem in the desired axial operating position and enabling manual axial movement of the winding stem between different operating positions with a click action. The detent spring has an elongate portion which extends in side-by-side relationship along the length of the winding stem, and a detent portion connected to the elongate portion for engagement with the winding stem grooves. The thickness of the detent spring is no greater than the thickness of the winding stem and by arranging the two in side-by-side relationship, a thinner timepiece can be formed than would be possible if the detent spring extended above or below the winding stem.
