As brand ambassador for IWC Schaffhausen, Lewis Hamilton had the opportunity to play a part in the design of his own, personal Ingenieur Chronograph Edition “Lewis Hamilton”. And the result is impressive: his Ingenieur Chronograph strikingly encapsulates and interprets the technology behind “Performance Engineering”. To achieve this he uses high-tech materials from FORMULA 1, which are found in the carbon dial, the crown and push-buttons, and the zirconium oxide screw heads. For Lewis Hamilton there was only one material for the case and bracelet: titanium. With a satin finish, the light grey metal used for the high-performance components in motor sport is particularly appealing. The rugged timepiece is equipped with IWC-manufactured 89361 calibre. The special edition, which is limited to 250 watches, has a special feature on the reverse side: inset into the titanium case back is a medallion of carbon, which may well show signs of wear and tear. A certificate supplied with the watch confirms that the material originally comes from one of the Silver Arrows built by MERCEDES AMG PETRONAS. The sapphire glass at the back of the watch bears a print of Lewis Hamilton’s personal insignia on the inside.
