A method for operating a counting device (90), such as a countdown device, or a timepiece movement (100) or a timepiece (200), the method including performing a first action on a first control member (C1) causing a first timepiece function to be returned to an initial state, and then performing a second action on the first control member (C1) causing an action of adjusting or winding a second timepiece function.

The display device is arranged in a timepiece which includes a counting wheel and a manual control mechanism which is arranged to permit cyclical starting, stopping and resetting of the counting wheel. The display device includes an indicating member, a unit for moving the indicating member into a first predefined position when the counting wheel is being reset, a unit for moving the indicating member into a second predefined position, different from the first predefined position, when the counting wheel is being started, and a unit for permitting the indicating member to be moved into a reading position following stopping of the counting wheel, the reading position being determined by the position of the counting wheel.

A push button system for activating an actuation member, the system including a button head, a pusher actuator integral with the button head, a first hollow guide member, the pusher actuator being mounted to slide inside the first hollow guide member, the first hollow guide member being intended to be secured to a fixed element relative to the button head and to the pusher actuator, a second hollow guide member arranged in the button head, and a pin mounted to slide inside the second hollow member, and intended to be secured to the fixed element. The pusher actuator has an upper portion provided on the periphery thereof with a collar intended to cooperate with an internal face of the first hollow guide member to guide the pusher inside the member.

The invention concerns a watch comprising a case having a middle part and inside which is housed a movement. The watch also includes a control member intended to be actuated by a user and an internal transmission device provided with an actuator, able to move, in response to actuation of the control member, between a rest position and an active position in which it actuates a mechanism of the movement. In an original manner, the transmission device includes a closed cavity filled with a fluid and a thrust means kinematically connected to the control member and arranged to displace the fluid inside the cavity, the displacement of fluid inside the cavity causing displacement of the actuator.
