Urwerk latest piece of mechanical ingenuity comes in the form of the above UR-210 Maltese Falcon. This fascinating timepiece will feature the worlds-first winding efficiency indicator – with a single hand drifting between the green and red ends of a curved scale.  The rotor can also be fully stopped for manual winding. Retails for 137,000 CHF (approximately $146,113 USD), and the first ten units will be out in October.
