By use of semiconductor pressure sensors, we have successfully developed a pressure sensor for the Citizen Depth Meter, which satisfies all the necessary conditions to be equipped in watches. This pressure sensor is formed very compact, 6.35 mm in diameter and 2.5 mm in thickness, and is very accurate. Therefore, a deapth measuring function with high accuracy which has not been available until now can be introduced into watches for the first time.
