No other model expresses the fascination of IWC Schaffhausen aviator's watches like the Big Pilot's Watch. The functional design that evokes the on-board instrumentation and the oversized conical crown are inspired by military watches of the 1940s. The Big Pilot's Watch 43 is a faithful interpretation of this original design, without the addition of elements to the dial and with a 43 mm steel case that combines an extraordinary presence on the wrist and maximum comfort. This model features a blue dial, rhodium-plated hands and a blue calfskin strap. The IWC-manufactured 82100 caliber can be admired through the sapphire crystal caseback. The Pellaton winding system has been reinforced with ceramic components and allows you to accumulate a power reserve of 60 hours, while the practical EasX-CHANGE system and a selection of calfskin, rubber or steel straps ensure maximum personalization. Combined with the case now water resistant to 10 bar, these features transform the Big Pilot's Watch 43 into a modern and extremely versatile sports watch.
