Abstract:
A watch, in particular a dive watch, having a movement which is arranged in a watch case and can be used to drive an hour hand via an hour tube and a minute hand and, if appropriate, a second hand via a minute tube in a fashion sweeping over a dial, as well as having a pressure detecting device for detecting the ambient pressure outside the watch case and a display for representing the detected pressure values, wherein 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 whcih a mechanical depth measurement mechanism (17) of a mechanical display can be driven;wherein the mechanical depth measurement mechanism (17) has a display shaft (22) which can be rotatably driven by the pressure transducer and carries a depth hand (6) which can sweep over a depth scale 15); the pressure transducer is an annular spring pressure gauge with an annular Bourdon spring (19) of which one end is fastened on the watch case (12) and is connected to a measuring opening (30) and of which the other end, which can be freely swiveled radially, can drive in a movable fashion the depth measurement mechanism (17) by means of which the pivoting movement of the free end of the Bourdon spring (19) can be converted into a movement which can drive a display shaft (22) rotatably; and the end of the Bourdon spring (19) is fastened on the watch case (12) via a shaft (96) projecting radially from the watch case (12), it being possible for the shaft (96) to be adjusted in the direction of its longitudinal extent.
