Timepiece with a rotating control member

Abstract

The invention relates to a timepiece having a rotary control member, the rotary control member having a hollow cylindrical body coaxial with the axis of rotation of the rotary control member, the hollow cylindrical body defining a hollow inner housing having or supporting a coaxial rotary disc on which is arranged a rotatable mark or logo motif visible from the exterior of the timepiece. The rotary disc rotates freely about its axis in or on the hollow cylindrical body, the rotary disc cooperating with a displacement device comprising an asymmetrically distributed weight to create an imbalance tending to rotate said rotary disc about its axis when the timepiece is in motion or when the control member has been rotated, so that, seen from the outside, the motif maintains a substantially fixed orientation.
