UR-110

“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.”

About

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

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.
