In 2013, IWC Schaffhausen became the “Official Engineering Partner” of the Mercedes-AMG PETRONAS Formula One™ Team. The Pilot’s Watch Mark XX Mercedes-AMG PETRONAS Formula One™ Team is the third official team watch IWC Schaffhausen has created for their longstanding motorsport partner. The 40-millimetre case is crafted from lightweight and remarkably rigid grade 5 titanium. Offering the highest strength-to-density ratio of any metal, titanium is also used in automotive engineering to produce car parts subject to immense stresses, such as engine valves. After machining and sandblasting, the surface retains an attractive greyish shimmer. Numerals and indices in the team’s signature green create a contrast with the black dial. The hands for the hours, minutes and seconds are coated with Super-LumiNova® of the same green color. At work inside the case is the IWC-manufactured 32111 calibre, an automatic movement with a power reserve of 120 hours. This watch is water resistant to 10 bar and fitted with a Petronas green rubber strap featuring the EasX-CHANGE® strap change system.
