In the URWERK tradition, none of the indications of the UR-111C watch are conventional: The minutes are shown in two different ways – linearly for eyes and digitally for precision. Never has a roller on the case performed the functions of the crown, nor have the running seconds meandered across a cluster of optical fibers. URWERK created a new interface with the watch. Instead of the conventional crown, they conceived a roller integrated into the top of the case.
Rolling the long fluted cylinder with your thumb to wind the watch is indeed a new sensation, but making it possible requires miniature gearing, complex articulations and intermediate wheels. The same applies to the original way of setting the time. Instead of pulling out a crown you swing out a lever from the side of the case and turn the roller in either direction. The hours and two versions of the minutes are displayed within glass sapphire covers along the side of the case so that you can see them at a glance without turning your wrist or letting go of the steering wheel.
