Urwerk is best known for their now-iconic satellite system, with spinning hour indicators integrated into a retrograde minutes display. This architecture is still there in the UR-210, but amped up a little. The minute hand is a three-dimensional cage inspired by the beak of the Maltese Falcon (which is what the Urwerk guys call the UR-210), and completely engulfs the hour satellite during it’s movement along the 120 degree arc. The hand looks monstrous (in the best way), but is 3-micron tolerance milled aluminum and weighs in at a super-light .302g. Utilizing a central spring and ruby bearing system, the flyback takes only .1 seconds at the change of each hour. At 1 o’clock is a traditional indicator for the 39 hour power reserve.
