的上升速率指示器机构包括第一轮组和一个压力传感器。 所述第一轮组连接到由压力变化驱动旋转的压力传感器。 该机构还包括第二轮组由从起始位置到测量位置对应于在压力的降低在单个旋转方向设置在第一轮驱动，脱开并返回结构以规则的间隔被致动以断开所述第二轮 设定和将其返回到开始位置时，连接到第二轮组上升显示机构率并包括布置成占据，在每个固定的间隔，有代表性的间隔期间在压力减小的显示位置指示器构件，和同步 在每个固定时间间隔致动的结构和布置，以保持一定间隔在显示件的显示位置。

The invention relates to an indicator mechanism of the rate of climb comprising a first mobile (1) and a pressure sensor arranged to mechanically deform under the effect of a variation in the pressure of the surrounding medium, the first mobile (1 ) being kinematically connected to the pressure sensor so as to be rotated in the event of variation of the pressure. Said mechanism further comprises a second mobile part (6) arranged to be driven by the first mobile (1) in one direction of rotation from a starting position into a measuring position corresponding to the pressure decrease, means disengaging and return (8) arranged to be actuated at regular intervals to disengage the second wheel (6) and to return it to the start position, a display mechanism of the rate of climb (10) kinematically connected to the second mobile (6) and comprising an indicator member (12) arranged to occupy at each regular interval a representative display position of the pressure decrease during said interval and thus the rate of climb, and synchronizing means (14) actuated in each regular intervals and arranged to hold said member of the indicator display position (12) during said regular interval. The invention also relates to a diving watch comprising a mechanical or electromechanical movement, and such an indicator mechanism of the rate of climb.
