DETAILS

Night finally enfolds the city. It is at this precise moment that the UR-220 SL Asimov comes to luminous life. A UR-220 model whose hours satellites glow as they gently emit the light stored up during the day. A fluorescence that accompanies the counting of the hours and renders it visible. Like phosphorescent photons, molded Super-LumiNova satellites enliven the baseplate of the UR-220 SL Asimov, giving light to the night.

The UR-220 SL Asimov indicates the time utilizing luminous truncated pyramid-type hour transporters. The cube shape featured in previous versions of the UR-220 resulted from meticulous work on UR Urwerk’s CNC machines. In this iteration, these elements free of any sharp edges are cast from a silicon mold and hand-adjusted to ensure their perfect finish. Their degree of hardness at the end of the process is close to that of ceramic. This technical expertise was developed by the Swiss company RC Tritec, which has 80 years of experience in the field.

The back of the UR-220 SL Asimov features a digital Oil Change gauge appearing on two adjacent rollers. The wearer of the watch triggers this device by removing a protective pin and pressing a pusher to activate the counters that will display the mechanism’s active running time in months. After 39 months – three years and three months – a service is recommended, and once this is complete, the Urwerk teams reset the counter and replace the pin.
