Urwerk is best known for their now-iconic satellite system, with spinning hour indicators integrated into a retrograde minutes display. Their latest piece of mechanical ingenuity for the UR-210 Maltese Falcon features the worlds-first winding efficiency indicator – with a single hand drifting between the green and red ends of a curved scale. What does this all mean? Essentially, the wearer can inject power into the watch with a rigorously planned day/night or rely on stored energy for days spent lounging around the house. In addition, the rotor can be fully stopped – thus turning the watch into a manual winder. Urwerk’s Felix Baumgartner comments, “It doesn’t just measure a universal value in a completely original way, but starts a real dialogue between the watch and its wearer.” The first ten pieces will be hitting retailers in October with a price of 137,000 CHF (approximately $146,113 USD).
