Specialist note
An incredible piece of engineering and haute horologie, the UR-202 has taken the traditional idea of using air friction and refined it to control the rate of automatic winding. Cutting-edge miniature twin turbines can be seen spinning on the back of the watch and are coupled with the rotor. According to the position of the selector lever, the turbines act as shock absorbers. In normal activity they cushion sharp movements of the rotor. This reduces wear and increases the lifespan of the movement.
While the selector position is continuously variable, the three principal positions are: normal activity, where the turbines spin freely; vigorous activity, where the air pressure generated by the turbines reduces the winding rate by approximately 35%; and extreme activity, where the turbines and rotor are fully blocked.
In addition to the technical accomplishments of the watch, the UR-202 uses a patented Revolving Satellite Complication which displays time using telescopic minute hand which operates through the middle of three orbiting and revolving hour satellites.
