The invention concerns a portable electronic apparatus () including a dial () provided with at least one aperture (), a support piece (), fixed in relation to the dial, arranged for receiving display means (). The support piece has at least first (-) and second (-) bearing surfaces defining a fixed position for the display means in the support piece in relation to the aperture in the dial, the fixed position being defined in a parallel plane to the dial. First (), respectively, second () mechanical means are provided for moving the display means in abutment against the first, respectively, second bearing surfaces, in the fixed position that they define.

Positioning and locking mechanism of display means in a portable electronic apparatus

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.
