Abstract
Abstract A timepiece for underwater use, includes a conventional movement arranged within a case and a manometer in the form of a resilient tube arranged in the space between the movement and the inner surface of the case. An open end of the tube communicates with ambient medium around the case and pressure variations in the tube are communicated to an indicator by means of a pin mounted on the opposite closed end of the tube. The pin is arranged between two legs at one end of the indicator.
