The current watch, a RM030 is housed in a tonneau-shaped case constructed from pink gold and titanium. The movement is an automatic RMAR1 caliber, a skeletonized movement with hours, minutes, seconds, date, winding indicator, power-reserve indicator and declutchable variable-geometry rotor with 55-hour power reserve. The innovation with the RM 030 is to combine automatic clutching and declutching control of the winding system with a torque sensor, thus ensuring an ideal degree of spring tension for the perfect supply of torque to the movement.

The patented declutchable variable-geometry rotor took 4 years to develop. The winding barrel is automatically disconnected from the rotor’s winding mechanism as soon as the spring is fully wound. When the power reserve reaches 50 hours, the rotor is declutched automatically thanks to a specially developed gear system. As a result, the rotor is disengaged from winding the barrel. Conversely, when the power reserve decreases to 40 hours, the rotor is automatically clutched, and the watch starts another winding phase until the indicator reaches 50 hours. This solution allows both the movement and the oscillator to operate at the best ratio of constant torque/power providing optimal chronometric performance.

It is possible to check on these phases thanks to the rewinding indicator located at 12 o’clock, which keeps the user informed whether the rotor is operating in the winding phase (on) or is disengaged (off). 

The current watch is part of a limited edition run of 30 pieces for Mexico and is presented in excellent condition.
