In addition to URWERK’s trademark satellite configuration of the wandering hours and minutes, the UR-100V Iron brings your spin through space into sharp focus. When the minutes hand has completed its 60-minute journey, it reappears on a 20-minute scale of 555 kilometres. This is the distance you travel in 20 minutes if you are standing on the equator of our rotating planet. The opposite scale tracks your journey through space around the sun: 35,740 km every 20 minutes. In the display on the UR-100V Iron, time and distance are on a par, the hours and minutes in blue, and the kilometres in bright white.
Under the UR-100’s dome, URWERK’s new calibre 12.02 drives the carousel carrying the wandering hours on three satellites. This new movement enabled a redesign of the carousel, bringing the hours closer to the minutes as they travel in succession along the 60-minute scale. The result is an easier and more intuitive reading of the time. This carousel, as well as the structure on top of the hours, are forged from anodised aluminium then sanded and shot-blasted, while the satellite screws are each circular sanded. The satellites rest on a carousel of sanded brass plated in ruthenium. The structure on top of the hours display is in sanded and shot-blasted aluminium. The self-winding rotor of the UR-100 is governed by a profiled airscrew known as the Windfänger.
