Abstract (en)
[origin: WO2007069028A2] The depth measuring device for a diving watch, more particularly a watch with a chronograph mechanism, comprises a plunger (343) which is moved by external pressure through a rolling membrane (346) against the action of a return element. The plunger acts on cams (351) belonging to a circular slide (350) mounted in a casing ring (330). The movement of the slide (350) is transmitted by a gear train (359) to a depth needle (307) and to a dead needle (308). A pressure sensing device (324) comprises a sliding plunger mounted inside the winding button (314). This plunger acts on a control device (325) for automatically starting and stopping the chronograph mechanism. A locking device (327) is used to lock and release the control device (325) and displays a diving flag (443) in the released position. The gear chain (359) is also designed to display a safety flag (389) at a predetermined depth. A resetting device (328) allows the various mechanisms and devices to be reset to zero. This construction provides a depth measuring device that can easily be incorporated into pre-existing watches and permits automatic starting and stopping of the chronograph mechanism.
