The Pilot's Watch Chronograph Edition "Mercedes- AMG Petronas Motorsport" (Ref. IW389005) is limited to 50 watches, featuring a black ceramic case and a black carbon fibre dial. The small seconds at 6 o'clock and the seams on the black calf leather strap provide accents in the team colour of PETRONAS Emerald Green. The IWCmanufactured calibre 89361 displays the timed hours and minutes together on a subdial at 12 o'clock. With the flyback function, a simple press of the reset button can instantly start timing again. This function is also used on the race track to determine the fastest lap time. The two watches are now available in IWC Boutiques or from authorised retailers.
