Official description

The Big Pilot’s Watch 43 Spitfire (Ref. IW329701) features a case, case back and crown made from lightweight and robust grade 5 titanium. The dark grey matte colour results from an elaborate surface treatment in which the components are first polished and then sandblasted. The design of the black dial was inspired by historical observation watches. Only the minutes and seconds are printed in white on the outer ring, while the hours appear smaller and in a more discreet grey print on the inner ring. Traditionally, this layout made it easier for pilots and navigators to read the minutes and seconds at just a glance. They needed this information to perform tasks like celestial navigation during visual flights. The distinctive field watch design is complemented with a brown calfskin leather strap with contrast stitching.
