Abstract

A timepiece having a stem (2) and an indication corrector member (3,4) such that the stem (2) may be moved manually from a non-correction to a correction position in which a calendar or time indication of the timepiece can be corrected by the indication corrector member (3,4) by effecting rotation of the stem (2) characterised in that the stem (2) has a corrector member driving portion (2c,2d), the indication corrector member (3,4) being drivingly disconnected from the stem (2) and being drivingly connected thereto by way of the driving portion (2c,2d) when in the non-correction and correction positions respectively.
