Urwerk 201 - Innovation Satellite Watch

An innovative Revolving Satellite Complication displays time on the 201. Telescopic minute hands operate through three orbiting and revolving hour satellites. These telescopic hands precisely adjust their length following the minutes and then retract. Extended, they enable the 201 to display the time across a large easy-to-read, dial. Retracted, they allow for a shorter and more comfortable case.
