A watch module comprising a rotary dial (1) possessing an opening (2) for displaying a complication or an image. This rotary dial (1) is mounted rotatably on a base dial (3) via an annular low-friction member (4). This rotary dial (1) can be pivoted through a certain angle by the action of a pusher (9, 9') to display another complication or image through the opening (2). This watch module, which comprises various parts (8, 13, 19, 21) for arresting and coupling the rotary dial (1) to the base dial (3), is arranged on the one hand in such a way as to decouple the rotary dial (1) from the base dial (3) when the pusher (9, 9') is pushed, and on the other hand to drive the rotary dial (1) when the pusher (9, 9') is released.
