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.
