Urwerk UR-101 Green Mamba Watch
Urwerk's first watch, the UR-101 from 1997, returns in black steel with an emerald-green minute scale. Instead of traditional hands, the Green Mamba uses two satellites to carry the hour numerals across a 180-degree arc, and its position along the scale gives the minutes. The two satellites take turns, with the second picking up as the first reaches the end. The 41 mm case is coated in black PVD and measures just 10.3 mm thick, and the strap is black rubber lined with calfskin. Urwerk will make only 50 Green Mambas.
