Our days are governed by our silent spinning orbit around the sun. We passengers unwittingly travel several billions of kilometres through space every year on our rotating planet at an average speed of 30 kilometres a second. It’s a journey displayed on the dial of the UR-100 GunMetal. In addition to Urwerk’s trademark satellite configuration of the wandering hours and minutes, the UR-100 GunMetal 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: 35,740km every 20 minutes. In the display on the UR-100 GunMetal, time and distance are on a par, the hours and minutes in vivid green, and the kilometres in bright white.
Under the UR-100’s dome, Urwerk’s calibre 12.01 movement drives the carousel carrying the hours on three satellites that travel in succession along a 60-minute scale. Each is forged from anodised aluminium then sanded and shot-blasted. 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 bi-directional selfwinding rotor of the UR-100 is governed by a profiled airscrew known as the Windfänger. There’s a nostalgic look about the case of the UR-100. Many owners of Urwerk watches will remember the independent brand’s first models.
