Inspired by the brand’s heritage of WWII pilot’s timepiece IWC B-Uhr Calibre 52 T.S.C from the 1940s, the IWC Big Pilot’s Watch Heritage ref. IW501005 takes on a modern spin of the oversized watch in 2017. Encased in a 46.2mm diameter bronze case that is prone to develop attractive patina overtime, the model resembles the appeal of vintage military timepieces. Designed as a true no-frills instrument made to aid navigation, the case is protected against magnetic fields with a soft-iron cage encircling the movement. Inside the Big Pilot beats the calibre 52110 with a hacking seconds function and offers a power reserve of 7 days without interruption. Fitted with a matte black dial and blued propeller-shaped hands, the luminescent material is charmed with a matching fauxtina that complements its antique appeal. Produced in a limited edition of 1,500 pieces, the present example is offered by its original owner and is accompanied with its full accessories.
