A watch, in particular a dive watch, having a movement (16) which is arranged in a watch case (12) and can be used to drive an hour hand (3) via an hour tube and a minute hand (4) via a minute tube in a fashion sweeping over a dial (1). Also present is a pressure detecting device for detecting the ambient pressure outside the watch case (12) and a display for representing the detected pressure values. There is arranged in the watch case (12) a mechanical pressure transducer to which the ambient pressure outside the watch case (12) can be applied and by means of which a mechanical depth measurement mechanism (17) of a mechanical display can be driven.
