“The UR-202 has the force, the character and the aggression necessary to hold onto the minutes. The UR-202 is like a living machine adapting to its environment, reacting and transforming its temporal path.” MARTIN FREI

REVOLVING SATELLITE COMPLICATION WITH TELESCOPIC MINUTES HAND

The UR-202 S Turbine Automatic features the patented revolving satellite complication with the added bonus of an innovative new winding system regulated by compressed air! The UR-202 is the world’s first watch with the winding rate regulated by fluid dynamics.

As long ago as the 18th century, clockmakers were using air friction to regulate the speed of chiming clocks, and their techniques evolved to become the preferred method of regulating the rate of chimes on minute-repeaters.

With the UR-202, URWERK have taken the traditional idea of using air friction and refined it to control the rate of automatic winding. The traditional rotating vanes of the past have been replaced by cutting-edge miniature twin turbines - miniature air compressors - which can be seen spinning on the back of the watch.

The UR-202’s twin turbines are coupled with the winding 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.
