A device for fastening a back () to a middle () of a watch case (), the back () being arranged to be driven onto the watch case (). The device includes a casing ring () to which is connected at least one position pin (), the position pin () being arranged to cooperate with at least one machining () in the back () so as to guarantee the orientation of the back () relative to the middle () along the 12 o'clock-6 o'clock axis of the watch.

Orientable back for a timepiece

A closing/opening system for a case of a timepiece is defined particularly in first and second parts of the case. The system includes a device for producing a mechanical connection, particularly a bayonet connection between these first and second parts and a device for creating a friction torque between these first and second parts. The device for creating a friction torque includes tightening faces to cooperate with one another when closing/opening the case and which are defined in the first and second parts. The system further includes a tightening element in one of these two tightening faces. The tightening element generates a constant friction torque during a course of travel of one of the two parts relative to the other when closing/opening the case of the timepiece.
