To mark its cooperation as an official engineering partner of the MERCEDES AMG PETRONAS Formula One team, IWC rolled out the Ingenieur Chronograph Racer in stainless steel with an engraving of a Formula One racing car on the case back. - Brushed/satin finished stainless steel with polished finished beveled corners. - Brushed stainless steel bezel with an engraved & black filled Tachymetre scale. - Strap: Black rubber with blue alligator leather inlay. - Applied polished blued steel index hour markers with luminous fill. - Black printed minute/seconds track on a raised black flange at the dial perimeter. Red “60” was inspired by the digital display on the steering wheel of the MERCEDES AMG PETRONAS Formula One Team racing car. - Polished blued steel hands with luminous fill, hour & minute hands partially skeletonized. - Date window located at the 6 o'clock position. - Small running seconds hand in the sub-dial at the 6 o'clock position. Dial: - Main silver dial with a very fine concentric circle brushed finished. - Polished steel rimmed sub-dials. - Silver sub-dials with a flat center & a concentric circle textured perimeter. Chronograph/Stopwatch function: - Features a "Flyback" function which allows instant restarting of the chronograph with a single push of the button rather than the need to stop, reset & then start the stop-watch again. - Large central seconds counter. - The chronograph sub-dial at the 12 o'clock position doubles as both the chronograph 60 minute counter (longer hand pointing to outer diameter) & the 12 hour counter (short hand pointing to marking on inner diameter), allowing for an easy & instant reading of the stopwatch. - IWC calibre 89361, beats at 28,800 vph, contains 38 jewels & has an approximate power reserve of 68 hours.
