IWC Schaffhausen Big Pilot’s Watch Perpetual Calendar TOP GUN Woodland 46.5 mm Green Dial Ceramic Strap IW503101

The Big Pilot’s Watch Perpetual Calendar TOP GUN Woodland features a 46.5-millimeter case made of green ceramic, inspired by the flight suits of naval aviators and the vast forest landscapes these elite pilots fly over. For this watch, IWC Schaffhausen has manufactured a ceramic bracelet for the first time. Thanks to the light weight of ceramics, the bracelet offers a high wearing comfort on the wrist. The H-link bracelet is assembled from 38 ceramic parts, which are produced in an elaborate process. The powdered raw materials are shaped to a green body and then machined close to their final shape. During the subsequent sintering process, the parts shrink by around a third. This decrease in size must be factored in already during the design phase. The case back ring and crown are made of Ceratanium®, an IWC-developed material combining the lightness and structural integrity of titanium with a hardness and scratch-resistance similar to ceramic. The perpetual calendar automatically recognises the different lengths of the months and adds a leap day every four years at the end of February. It will only need a manual adjustment in centuries when the leap year is skipped, for example, in the year 2100. The Double MoonTM display shows the moon phase as it can be seen from both the Northern and Southern hemispheres. Thanks to special reduction gear train, it is so precise that it will only deviate by one day after 577,5 years. Featuring a Pellaton winding system with ceramic components, the IWC-manufactured 52616 calibre stores a power reserve of 7 days in two barrels. The movement is visible through the tinted sapphire glass case back.
