New Urwerk Rebel - UR-202 'Turbine Automatic'

May 02, 2008
Urwerk, famous for its rebellious approach towards contemporary watchmaking, has unveiled its latest audacious timekeeping creation, the UR-202. The new Urwerk watch has incorporated the brand's patented Revolving Satellite Complication. Moreover, UR-202 boasts an innovative new winding system regulated by compressed air.

The Urwerk UR-202 is equipped with calibre UR 7.02, an automatic winding movement with the twin turbine regulation. The amazing timepiece provides the following functions: patented revolving satellite complication with integral telescopic minutes hands; moon phase indicator; day/night indicator.

The case of the timepiece has been produced in a choice of white gold, red gold, black PE-CVD platinum and AlTiN. The dial of the UR-202 features 'carousel,' mirror-polished by diamond cutter. The hours and minutes markers of the watch have been provided with SuperLumiNova treatment.

The Urwerk UR-202 has been destined to become the first watch with the winding rate regulated by fluid dynamics. Starting with the 18th century, clockmakers used air friction for regulating the speed of chiming clocks. Such techniques turned out to become the preferred way of regulating the rate of chimes on minute-repeaters.

While developing the UR-202, Urwerk used the well-known method of using air friction and applied it to control the rate of automatic winding. The creators of the watch replaced the rotating vanes of the past by cutting-edge miniature twin turbines. You can see these miniature air compressors on the back of the watch.

The UR-miniature twin turbines are coupled with the winding rotor. Depending on the position of the selector lever, the turbines act as shock absorbers. In normal activity they cushion sharp movements of the winding rotor, thus reducing wear of the movement.

The Revolving Satellite Complication incorporated by the UR-202 shows time with help of telescopic minutes hands that operate through the middle of three orbiting and revolving hours satellites. The telescopic minutes hands are developed to precisely adjust their length to follow the three sectors featuring the minutes markings: 0-14, 15-44, 45-60. The extended telescopic minutes hands allow the UR-202 watch to show the time across an easy-to-read dial. When the hands are retracted, they allow for a very comfortably-sized case.

The major component of the Revolving Satellite Complication is the brand's patented carousel. This component manages the rotation of the hours satellites, as well as the integral telescopic minutes hands. High-precision 'transporters' control the length of the minutes hands, with one end of each transporter following a cam plotting the path of the minute indication, and the other controlling the precise length of the minutes hand.

There is one transporter for each minutes hand. The transporters allow the telescoping hands to adjust their length as they follow the minutes scale's vectors. One end of the transporter follows a cam that simulates the path of the three vectors, while the other is responsible for controlling the length of the minutes hand. The cam's shape was created by plotting 380 points of reference to make the minutes hands extend and retract to the precise length.
