The invention includes a device for securing a back cover on a middle part of a watchcase, characterized in that it includes an intermediate element to which the back cover is connected, the intermediate element being screwed onto the middle part of the watch, an element arranged to allow the back cover to drive the intermediate element in rotation until the latter reaches a locked position on the middle part, the back cover also being pivotable relative to the intermediate element without the latter being unscrewed for alignment with the 12 o'clock-6 o'clock axis of the watch.

Device for securing a back cover to the middle part of a watch

The invention comprises a timepiece including a middle part () and a bezel () capable of rotating on the middle part (), the bezel () and the middle part () delimiting between them an annular chamber () in which there is arranged a sealing gasket () with a U-shaped profile. A compression member () such as an O-ring type joint with a smooth external surface is housed in the sealing gasket ().

Timepiece comprising a rotating bezel

The invention concerns a timepiece including a case () and a crystal () together defining a housing () for a movement (), and further including an element that is mobile in rotation () actuated by a control member () including a stem () of longitudinal axis AA, passing radially through said case (), a crown () mounted on a first proximal end of said stem and a pinion () fixedly mounted in rotation on a second distal end of said stem (). The control member () is fitted with a part () for axially securing said pinion () on said stem (), arranged on the proximal side of said stem (), said securing part () including:

Watch with rotating element

An element made of elastomeric material (,) is made by overmoulding between the middle part (,) of a watch case and a support ring, in particular a casing ring (,) intended to support the watch movement. This allows the constraints of the inner form and inner machining of the middle part to be reduced, while allowing accurate positioning of the internal elements of the watch with respect to the middle part. The elastomeric element (,) can also assure sealing with the control stem and/or the crystal of the watch.
