HOMAGE TO A LEGEND With the Ingenieur Chronograph Silberpfeil, IWC has breathed fresh life into the legend of the historic Mercedes-Benz racing car. One characteristic feature is the dial with its circular graining in silver or brown. This is a tribute to the mythical status of the Mercedes Silver Arrow W 25, whose dashboard had a steel surround with circular-grain decoration. The efficient double-pawl winding in the IWC-manufactured 89361 calibre is one of the most outstanding achievements of haute horlogerie currently on offer. The upper totalizer makes it possible to read off stopped hours and minutes as simply as the time on a subdial. Stopped times up to one minute are measured by the central seconds hand. Used in combination with the tachymeter scale, this provides the speed at which a reference distance of 1,000 metres has been completed. Another very practical feature for anyone who frequents the world’s racing circuits is the fly-back function for measuring pit-stop times. The chronograph features a black rubber strap with a brown alligator leather inlay. This, too, was inspired by the world of motorsport in the 1930s, when thick leather belts were omnipresent on motorcar bonnets. An attractive engraving of a stylized Mercedes Silver Arrow racing car can be found onthe case back. Between 1934 and 1939, Mercedes-Benz chalked up countless Grand Prix and other championship victories with its Mercedes Silver Arrows. Both dial versions are available in limited editions of 1,000 watches. In tribute to the Mercedes Silver Arrow W 25, whose dashboard had a steel surround with circular-grain decoration IWC present the Ingenieur Chronograph Silberfeil in stainless steel with an engraving of a stylized Mercedes Silver Arrow racing caron 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 brown alligator leather inlay. - Applied polished stainless steel index hour markers with luminous fill. - White printed minute/seconds track on a raised brown flange at the dial perimeter. - Polished stainless steel hour & minute hands, partially skeletonized & with luminous filled tops. - Blackened steel sub-dial hands, partially skeletonized & with luminous filled tops. - 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 brown dial with a circular grained pattern finish. - 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 red 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.
