Portable electronic appliance including a pressure sensor

The invention claims a wearing arranged on the electronic device, for example diver's wrist watch or the height gauge, a pressure sensor (10) of the external shell (2) a surface (9) chamber (11) arranged in the meter, and composed of a cover (13) is; the cover is at least manhole (32) is used to the chamber transmission and pressure. The sensor (12) is arranged on a sealing gasket is in the chamber. The radiation door (14) is placed between the central head (31) and sensor exposed surface (22), so as to the solid and/or the sunshine and sensor. Preferably, the heat dissipation door is fixed on the cover plate and depicting layer, and hole on the plate (42) is opposite to each hole (32) is shift of the cover, for pressure and is capable to the sensor of transmission groove of exposed surface of the outer.
