The device has a pressure sensor mechanism (340) comprising a plunger (343) intended to be displaced by hydrostatic pressure against the effect of a Belleville spring washer. The displacement of the plunger is transmitted by a transmission element (342) to a depth needle (307) and a dead needle (308) of a watch. The transmission element has a circular slide (350) pivoting with respect to a casing ring (320) of the watch and a gear chain (359). |
