HANDOUT ? The Ingenieur Chronograph Edition ?W 125? (Ref. IW380701) from IWC Schaffhausen features a case in titanium, silver-plated dial and striking black hands and appliques, together with a black calfskin strap. The watch takes up the theme of the Mercedes-Benz W 125 Silver Arrow, which was designed by Rudolf Uhlenhaut and dominated the competition as emphatically as the current version of the Mercedes Silver Arrow heads up motorsport?s premier competition today. The timepiece is limited to 750 pieces. (PHOTOPRESS/IWC)
