Cam, transporters, telescopic hands; the UR-203 reveals it micro-mechanics for all to see. Within this Edition Spéciale limited to 20 pieces the cams, the rubies and the transporters that ensure the ultra-precise alignment of the telescopic hands indicating the minutes, are all revealed. Time is translated into a metallic choreography of sublime fluidity
This UR-203 in black Platinum is a wild idea of Martin Frei (URWERK co-founder and designer)”, explains Felix Baumgartner, URWERK co-founder and master watchmaker. “Martin imagined a stripped down model distilled to its pure essence. We had to start again at the beginning to develop this model, we sat down at the drawing board and completely reconsidered the satellite module. The horological challenge with this complication was to develop a complex mechanism with the minimum of components to ensure its reliability and longevity.
Revolving Satellite Complication The UR-202 features URWERK’s patented Revolving Satellite Complication with telescopic minutes hands. The Revolving SatelliteComplication displays time using telescopic minutes hands operating through the middle of three orbiting and revolving hours satellites. The telescopic minutes hands precisely adjust their length to follow the three sectors marking the minutes: 0-14, 15-44, 45-60. Extended, they enable the UR-202 to display the time across a large, easy-to-read dial. Retracted, they allow for a very wearable and comfortably sized case.
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, URWERKhave 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 The traditional rotating vanes of the past have been replaced by cutting-edge miniature twin turbines – miniature air compressors – which can be seen spinning on the back of the watch.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.
