IN ITS ELEMENT ON THE CIRCUIT

In 2013 IWC Schaffhausen embarked on the Formula One season as the Official Engineering Partner of the MERCEDES AMG PETRONAS Formula One™ Team. The designers, technicians and engineers on both sides share a common passion for precision and performance engineering. To mark this cooperation, IWC rolled out the Ingenieur Chronograph Racer in stainless steel with an engraving of a Formula One racing car on the case back. The rugged timepiece has been equipped with one of the most efficient movements manufactured entirely by IWC, the 89361 calibre. It displays stopped times in hours and minutes on a totalizer, while times up to one minute are measured by the central stopwatch hand. It also features a tachymeter scale that shows the average speed covered over a distance of 1,000 metres. Thanks to the flyback function, pressing the reset button brings the stopwatch hand back to zero and immediately restarts timing, making it perfect for recording pit-stop times. The chronograph is available with a slate-coloured dial and black totalizers or a silver-plated dial with silver-plated totalizers and blue hands. The red “60” in the chapter ring was inspired by the digital display on the steering wheel of the MERCEDES AMG PETRONAS Formula One™ Team racing car. Both watches are available with a black rubber strap and alligator leather inlay, as well as a stainless steel bracelet.

The 89000-Calibre Family

Designed and manufactured completely by IWC in Schaffhausen, the 89360-calibre chronograph movement and its successor, the 89361, feature a significantly improved self-winding system and set new watchmaking standards. The design, which occupied an IWC development team for a full 4 years, was necessitated by a revolutionary chronograph display that enables the user to read off even relatively long periods of stopped times – 8 hours and 52 minutes, for example – at a glance: a circular totalizer combines the hour and minute hands as if they were a watch-within-a-watch. In 2012, it was joined by the newly developed 89365 chronograph movement including a stopwatch function with minutes and seconds as well as a flyback function. After further development, the IWC-manufactured movement was known as the 89800 calibre and used for the big digital date and month displays in References 3761 and 3791. The new Ingenieur Perpetual Calendar Digital Date-Month comes equipped with a further development on the theme, the 89802 calibre.
