The IWC Big Pilot’s Watch Perpetual Calendar Top Gun Woodland (ref. IW503101) redefines military-inspired watchmaking through a bold use of ceramic and calendar complexity. Clad entirely in matte green ceramic with a matching rubber strap, it belongs to IWC’s experimental Top Gun line – a series known for its technical prowess and distinctive materials.

Encased in a 46mm ceramic case, the watch houses the in-house calibre 52615, an automatic movement capable of tracking the date, day, month, year, and moon phase with no manual correction needed until 2100. A double moonphase display shows both northern and southern hemispheres, while the Pellaton winding system ensures a robust 7-day power reserve. Water-resistant to 60m, the dial maintains clarity through luminous Arabic numerals and a practical layout of four subdials.

With its combination of high-durability materials and one of IWC’s most sophisticated complications, the IW503101 earns distinction among both military watch enthusiasts and perpetual calendar collectors. The unique “Woodland Green” colourway further sets it apart as a contemporary collector’s piece with unconventional appeal.
