A portable object including a case middle closed by a back cover, in which an electronic module is placed, the electronic module including a plate to which a printed circuit board is secured, the printed circuit board carrying at least one contact area connected to at least one input of at least one integrated circuit, the integrated circuit supplying at least one signal to an electronic signal processing device. The portable object further includes a detection member changing from at least a first position, indicating that the back cover is secured to the case middle, to a second position, indicating that the back cover is not secured to the case middle.

Case closure detection system for a portable object

The invention concerns a device for mounting a pressure sensor simply and precisely on the back cover () of a diver's watch or altimeter watch. The pressure sensor () is driven into an intermediate ring () forming part of a sensor module () which further includes an additional PCB (), a sensor support () and connecting elements () between the additional PCB () and a main PCB of the watch. To ensure very precise positioning relative to the back cover, the intermediate ring () includes feet () that engage in holes in the additional PCB and in the sensor support. A sealing gasket () is radially compressed between the wall of the orifice () of the back cover and a tubular casing () of the pressure sensor. The back cover () is covered externally by a perforated cover.
