An arrangement for arranging the measurement of external pressure in a wristop instrument, such as a sports computer, a diving computer, a wristwatch, or similar. The arrangement in the instrument comprises an instrument body (1),- at least one watertight space inside the instrument body (1), and at least one circuit board (2) situated in the watertight space. A flow path (6) is arranged through the instrument body (1) to the watertight space and this flow path (6) is closed by a membrane (7), which is permeable by a gas, but not by water, and which closes the flow path (6) watertightly. A pressure sensor (3) is situated in the watertight space that is formed. |
