• THE UR-110

The UR-110 continues URWERK's radical tradition of telling the time using orbiting satellite complications. In the UR-110, the time is always shown on the right side of the watch. The satellites follow a vertical line, graded from 0 to 60 minutes, in a downward motion. The UR-110 also features a Control Board on the dial side with indicators for “Day/Night” and "Oil Change" - URWERK's service interval display, as well as small seconds on a sub dial. Turning the watch over, the titanium back encloses an innovative automatic winding system regulated by dual turbines.

“The beauty of the UR-110 is in its apparent simplicity. We imagined time as a 'silent journey'. There are things happening on the dial that are not obvious at first glance. Everything looks normal; however, they are everything but.”

REVOLVING SATELLITE COMPLICATION ON PLANETARY GEARS

One of the challenges posed by this complication is working out the optimal architecture for supporting the central carousel and the rotating hour modules. We finally opted for a technical solution that is radically different from any of our other creations: instead of ball bearings, a fixed axis runs the full height of the watch, providing maximum rigidity and minimum play. The whole complication is perfectly balanced on this axis.
