About this reference
The Big Pilot's Watch 43 IW329303 gives IWC's large aviation design a blue-toned identity. Its 43mm stainless-steel case frames a blue dial and blue calfskin strap, creating a more tonal interpretation of the collection's unmistakable format. Convex sapphire with antireflective coating protects the display, while the see-through caseback reveals the mechanical character beneath the active reference's broad, purposeful face.
The 13.6mm case height makes the watch substantial, but the 43mm diameter keeps the Big Pilot profile deliberate rather than excessive. Automatic calibre 82100 supplies hours, minutes and central seconds, with 60 hours of power reserve. The 100m rating supports everyday versatility, and the 21mm lug width gives the blue EasX-CHANGE calfskin strap the right visual weight for the case.
