• THE UR-103

With the UR-103 models, URWERK takes its 'no limits' approach to haute horlogerie ever further. Four orbiting and rotating satellites display the hours, with each satellite indicating the time in both analogue and digital fashion as it arcs across the minute chapter. Turning the watch over reveals a new surprise: the Control Board. This control panel is reminiscent of the dashboard of a sports car and features precision indication of the minute and seconds for exact time-setting, power reserve indication and fine-adjustment screw.

“From the very beginning, we had the desire to create a watch that is in phase with its time, i.e. truly contemporary. While URWERK's motivation is to explore new paths, our timepieces draw from the culture of traditional fine watchmaking.”

HOUR SATELLITE INDICATION

The main technical challenge is ensuring excellent isochronal performance of the satellites while minimizing friction and loss of energy. No simple task as, together with the supporting orbital cross, the satellite complication weighs in at 160 times heavier than traditional hands.

We took up the challenge and chose high-tech materials to minimize mass and thus maximize chronometric efficiency.
