This 53.6mm x 43.8mm machine in titanium and steel features a unique indication developed by Urwerk. At the top left-hand corner of the dial is an indicator that displays the winding efficiency over the past two hours. Using this, the wearer can adjust the winding efficiency of the UR-7.10 calibre self-winding movement using a selector on the back of the watch. Turbines coupled to the movement, which offers a power reserve of 39 hours, manage this function, while Urwerk’s patented revolving satellite complication displays the time around the bottom half of the dial.
