In design, it is very close to IWC’s 1940 Big Pilot’s Watch, the legendary reference 431 that was 55 mm in diameter and 17.5 mm thick. This model is 40mm in diameter and 10.8 mm thick, making it wearable on most wrists. Includes the automatic Calibre 35111, based on the Sellita SW300-1, provides a 42-hour hour reserve.
