IWC – Ingenieur Chronograph Racer – IW378509
To mark the start of its partnership with the MERCEDES AMG PETRONAS Formula Oneª team in 2013, IWC launched the Ingenieur Chronograph Racer and the Ingenieur Chronograph Silver Arrow. The two technically identical timepieces are equipped with the highly efficient double-pawl winding system found in the IWC-manufactured 89361 calibre. The upper totalizer makes it possible to read off stopped times and minutes on a subdial as easily as the time of day. Stopped times up to one minute are measured by the central seconds hand. Used in combination with the tachymeter scale, it also shows the average speed achieved over a measured distance of 1,000 metres. Another very practical feature for anyone who frequents the worldÕs racing circuits is the flyback function for measuring pit-stop times. The Ingenieur Chronograph Silver Arrow breathes fresh life into the mythical aura surrounding the historic Mercedes-Benz racing car. One characteristic feature is the dial with its circular graining in silver or brown: a tribute to the legendary Silver Arrow W25, which had instruments framed by a dashboard of circular-grained steel. Both dial versions are available in limited editions of one thousand watches. An attractive engraving of a stylized Silver Arrow racing car can be found on the case back.
