The Big Pilot IW5020-03 (aka: 5020-03, IW502003), seen from the bench
The IWC Big Pilot IW5020-03 is a modern evolution of a legendary pilot watch from the 1940s, featuring a 46mm titanium and ceramic case. Powered by the automatic IWC 51111 calibre with over 7 days power reserve, it delivers extreme readability and operational precision without compromise. The 20mm lug width accommodates standard spring bars, while the titanium construction resists oxidation and maintains its satin finish under intensive use, with water resistance to 60 metres.
