UR-110

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 UR-110 also features a Control Board on the dial side with indicators for Day/Night and Oil Change, as well as small seconds.

Insights

Swiss timepieces satellite watch UR-110

Construction complexity

Central carousel provides the complication with stability and equilibrium. Planetary gearing assures the parallel rotation of the three hour satellites

Counter-rotating hour modules

Each module is mounted on a planetary gear and is in constant counter-rotation to balance the direction of rotation of the central carousel.

“Oil Change” service interval indicator

The “Oil Change” indicator alerts the user when a service is due. This counter is reset to zero when the timepiece is serviced.

“Day/Night” indicator

The Day/Night indicator is a rotating disk marked with dark Super-LumiNova® for the night, white for the day and a striped mix for dusk/dawn.

“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.”
