Notes

The four hour-satellites of the UR-103 are crafted in aluminium and are suspended under a grade-2 titanium orbital cross. The complication is mounted on a non-magnetic ARCAP P40 base plate providing superior strength and stability to traditional metals. The hour satellites complete a full revolution under the orbital cross every four hours. As the satellite approaches the crown position, an internal Geneva cross causes it to undergo a 120 degree rotation on its own axis. This 120 degree rotation positions the next hour for its turn indicating the time at the front of the dial. Over a one-year time span each orbital cross completes 2190 rotations and each satellite makes 730 revolutions on its axis. Urwerk's integration of a Control Board on the back of the 103 was a world first for a wristwatch. This "dashboard" features a 43-hour power reserve indicator, a chronometer with minutes and seconds facilitating accurate time setting, and, in a nod to Abraham Louis Breguet, a Precision Adjustment screw making it possible for the owner to precisely regulate the timing of the 103.09 to match his lifestyle.
