Everything worth knowing.

A detailed, evidence-led view of the product—not a generic sales summary.

IWC signed on as the official engineering partner of the Mercedes AMG Formula 1 team in 2013, aiming to showcase the Swiss and German companies' common passion for high-tech precision. One result of this collaboration has been the Ingenieur Chronograph Racer, a new series of stunning driving watches with breathtaking credentials and performance. The stainless steel watch features a single chrono subdial at 12 o'clock, acting as a totaliser for hours and minutes, mirrored by the small hacking seconds and date window at 6. The stopwatch flyback function is designed for timing pitstops or other back-to-back intervals, and the tachymeter is calibrated for average speeds over 1,000m. In a nice nod, the chapter ring has a red 60 seconds index as a reference to the digital steering wheel display of Mercedes race cars.
