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, moulded Super-LumiNova® satellites enliven the baseplate of the UR-220 SL Asimov, giving light to the night.
