URWERK UR-10 Spacemeter Blue Watch
URWERK built its name on satellites and wandering hours. The inspiration for the UR-10 Spacemeter's round dial and conventional hands came from an unexpected place: a 19th-century Gustave Sandoz clock, restored by co-founder Felix Baumgartner's father, that tracked planetary motion rather than time. The three sub-dials have nothing to do with chronographs or calendars: the counter at 2 o'clock tracks every 10 kilometers the Earth travels in its daily rotation, the one at 4 o'clock logs every 1,000 kilometers of its orbit around the Sun, and the combined counter at 9 o'clock synchronizes both. The caseback adds a peripheral 24-hour hand tracing the Earth's full rotation, with rotation and revolution shown in opposing directions. The Blue is the final edition of the UR-10, the third and last of three dial variants, limited to 25 pieces. The case measures 45.4 x 44mm, just over 7mm thick, in sandblasted titanium, worn on a matching single-link titanium bracelet. Inside, the UR-10.01 automatic developed with Vaucher Manufacture runs at 4Hz with a 43-hour power reserve, topped by URWERK's patented Dual Flow Turbine, a pair of counter-rotating propellers that regulate rotor speed through air resistance.
