The UR-202 is the world's first wristwatch featuring an innovative new winding system regulated by compressing air utilizing minature turbine
Time on the UR-202 is displayed using telescopic minute hands operating through the middle of three orbiting and revolving hour satellites. The telescopic minute hands precisely adjust their length to follow the three vectors 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; thus providing the wearer with the best of both worlds.
The UR-202 available in red gold, white gold, black PE-CVD platinum and ALTi.
The patented carousel is the critical component of the revolving satellite complication. It is responsible for not only the rotation of the hours satellites but also the integral telescopic minutes hands. This rotating central hub is an extremely complex part to manufacture due to the extreme precision and tight tolerances necessary.
Many of the carousel's intricacies have to be machined and finished to tolerances of 1/1000mm. High precision 'transporters' are used to control the variable length of the minute hands. One end of each transporter follows a cam plotting the path of the minute indication, while the other controls the precise length of the minutes hand.
