An ascent rate indicator mechanism includes a first wheel set and a pressure sensor. The first wheel set is connected to the pressure sensor driven in rotation by a pressure variation. The mechanism further includes a second wheel set driven by the first wheel set in a single direction of rotation from a start position into a measurement position corresponding to a decrease in pressure, uncoupling and return structure to be actuated at regular intervals to uncouple the second wheel set and to return it to the start position, an ascent rate display mechanism connected to the second wheel set and including an indicator member arranged to occupy, at each regular interval, a display position representative of the decrease in pressure during the interval, and synchronization structure actuated at each regular interval and arranged to maintain the display position of the indicator member during the regular interval.
A ascent rate indicator mechanism comprising a first wheel set and a pressure sensor arranged to deform mechanically under the effect of a pressure variation in the surrounding medium, the first wheel set being kinematically connected to the pressure sensor so as to be driven in rotation in the event of a pressure variation, wherein said ascent rate indicator mechanism further comprises a second wheel set arranged to be driven by the first wheel set in a single direction of rotation from a start position into a measurement position corresponding to the decrease in pressure, uncoupling and return means arranged to be actuated at regular intervals to uncouple and to return the second wheel set to the start position, an ascent rate display mechanism kinematically connected to the second wheel set and comprising an indicator member arranged to occupy, at each regular interval, a display position representative of the decrease in pressure during said interval and thus of the ascent rate, and synchronization means actuated at each regular interval and arranged to maintain said display position of the indicator member during said regular interval.
A diver's watch comprising a mechanical or electromechanical movement, and an ascent rate indicator mechanism comprising a first wheel set and a pressure sensor arranged to deform mechanically under the effect of a pressure variation in the surrounding medium, the first wheel set being kinematically connected to the pressure sensor so as to be driven in rotation in the event of a pressure variation, wherein said ascent rate indicator mechanism further comprises a second wheel set arranged to be driven by the first wheel set in a single direction of rotation from a start position into a measurement position corresponding to the decrease in pressure, uncoupling and return means arranged to be actuated at regular intervals to uncouple and to return the second wheel set to the start position, an ascent rate display mechanism kinematically connected to the second wheel set and comprising an indicator member arranged to occupy, at each regular interval, a display position representative of the decrease in pressure during said interval and thus of the ascent rate, and synchronization means actuated at each regular interval and arranged to maintain said display position of the indicator member during said regular interval, the uncoupling and return means and the synchronization means being arranged to be actuated by the movement at regular intervals.
