Following the British Royal Air Force request for a precise, reliable watch, resistant to magnetic fields, IWC Schaffhausen developed the Mark 11 and delivered it to them in 1948. The officially designated “navigator’s wristwatch Mk. 11 – Stores Ref. 6B/346” was the start of the legendary Mark series, and set the benchmark for the technical features and functional instrument design of most modern pilot’s watches.
This year, IWC Schaffhausen celebrates the 75th anniversary of the series with two new versions of the Pilot’s Watch Mark XX, launched in 2022 with blue, green and black dials. The new stainless-steel models have silver-plated dials. One version is fitted with a black calfskin strap, and the other features a high-grade 5-link stainless steel bracelet.
The 40mm steel case, water resistant to 10 bar, has been re-engineered with a revised side profile and improved lug geometry for a better fit on all wrists. The graphics for the numerals and indices on the high-contrast dial have been refined. Luminescent elements on the dial and the black hands ensure perfect readability in all lighting conditions.
The Pilot’s Watch Mark XX is powered by the IWC-manufactured 32111 calibre, an automatic movement designed to build a five-day power reserve. The front glass will remain intact even if the cockpit has a sudden pressure drop.

An integrated EasX-CHANGE® system lets the wearer change the strap or bracelet quickly and easily without any tools, customising their watch to suit mood and occasion. The range includes calfskin straps, stainless-steel bracelets and durable, flexible and waterproof rubber straps in lively colours.
The new versions of the Pilot’s Watch Mark XX are available through IWC boutiques, authorised retail partners or online at IWC.com.
