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 a both analogue and digital fashion as it arcs across the minute chapter. This sophisticated and ground-breaking complication is the result of years of research, development and testing.

Insights

Orbital cross and satellites
The orbital cross carries the four hour-satellites and an internal Geneva cross governs each of them. The hour-satellites complete a full revolution under the orbital cross every four hours.
Hour satellite
The time is indicated by an orbiting hour satellite passing the arc of the minutes.
Plate
The complication is mounted on a non-magnetic ARCAP P40 triple base plate providing superior strength and stability to traditional metals.

Control board – world first
The control board on the back of the UR-103 was inspired by vintage marine chronometers which placed their less frequently used functional indications on the back of the timepiece.
Power Reserve indicator
36-43h power reserve.
Chrono Meter for precise time setting
Chrono Meter with dual 15 minute and seconds dial facilitating accurate time-setting.
Fine Tuning screw
In a nod to Abraham-Louis Breguet, a Precision Adjustment screw allows the user the possibility of adjusting the watch's timing (about +/- 30 seconds per day).

Indications
“URWERK's UR-103 is the result of nearly three years of development and a further two more years of testing... the end result went beyond our dreams.”
