Abstract: A timepiece with a movement that includes: a power source; an element for displaying the current time; a chronograph mechanism including a control mobile (60) including at least one control member for activating the start, stop and reset functions of the chronograph. The control mobile (60) further includes a driving member having a toothed sector (84) kinematically connected to the control member. The timepiece further includes a button that can be rotated, the button being rigidly connected by teeth that can be kinematically connected to the toothed sector so that the pivoting of the button activates the start, stop and reset functions of the chronograph.

Abstract: 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.
