Abstract: A crown head for a timepiece includes a cap, a tube secured in a timepiece case, a central pipe engaged with the tube, and a safety valve with a discharge channel in fluid communication with the inside of the case when the valve is in an open configuration, to discharge excess fluid. The safety valve also includes a piston fitted inside the central pipe and an elastic member to cooperate with the piston, which can be displaced axially according to the pressure variations inside the case. The crown head also includes a blockage which prevents separation of the cap and the tube. The blockage includes a shoulder arranged on the inner wall of the tube, and includes a support surface against which part of the piston can abut, and a rim provided at the base of the central pipe to abut against a shoulder on the piston.

Abstract: An automatic safety valve for a timepiece, especially for a diving watch. The valve includes a valve head, a tube designed to be secured in a case of the timepiece, and an evacuation channel arranged so as to be in fluidic communication with the inside of the case when the safety valve is in an open configuration so as to evacuate an excess of fluid. The safety valve further includes a pressure regulator arranged inside the evacuation channel to maintain the outlet speed of the fluid.

Abstract: 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.

Abstract: Crown including a cap formed of a cover integral with a lateral skirt, wherein the crown includes a removable deck ring.

Abstract: The present invention concerns a crown for a timepiece comprising a disconnecting gear device for preventing damage to the components of the movement of the timepiece in which it is implemented. For this purpose, the crown is provided with a housing which houses a pipe, to which one end of a winding stem is connected, carrying at least one spring and a rigid ring secured to the crown and comprising notches adapted to cooperate with the spring. In common use, a rotation of the crown causes a rotation of the pipe and thus of the winding stem, via the rigid ring and the spring. Owing to the device according to the present invention, when the mechanical resistance to the rotation opposed by the winding stem, via the pipe, exceeds a predefined threshold, the spring is deformed and is no longer driven in rotation by the rigid ring. Consequently, the winding stem is no longer driven in rotation in such conditions.

Abstract: An operating means such as for example a crown, with an element rigid with the housing and with an operable element which is movable with respect to this. Between these two elements there is arranged a lip seal with an elastic lip, which bears on the element rigid with the housing and delimits the timepiece inner space to the surroundings. By way of the fact that the lip is led in the direction of the surroundings conically onto the element rigid with the housing and lies on this element with pretensioning, on the one hand with an inner space excess pressure it may release itself from the element rigid with the housing for the purpose of pressure compensation between the inner space and the surroundings and on the other hand with a surrounding excess pressure it is more strongly pressed on the element rigid with the housing for the purpose of sealing the inner space with respect to the surroundings.
