The flagship of IWC, the Big Pilot’s Watch is a distinctive timepiece in steel with a diameter of 46.2mm and a height of 15.8mm. The manufacture 51110 caliber is currently the world’s largest automatic movement. It builds up the necessary energy for an 8.5-day power reserve in the shortest possible time via the patented pawl-winding mechanism (Pellaton system) and operates for precisely 168 hours or seven days before the ingenious power-reserve train stops the movement mechanically.
