INGENIEUR CHRONOGRAPH SILBERPFEIL
With its Ingenieur Chronograph Silberpfeil, IWC breathes fresh life into the legend of the historic Mercedes-Benz racing car. The designers took their inspiration from the illustrious W25 while the technicians equipped the chronograph, as only fitting, with a highly efficient IWC-manufactured movement.
An old black-and-white photograph taken at a motor race in Bern in 1936 records a very special moment: it shows Albert Pellaton, IWC Schaffhausen's future Technical Director, walking along the Mercedes-Benz pit and a line of W25Silver Arrow racing cars. In the background we see the Mercedes team mechanics and even Mercedes' well-known racing-team manager, Alfred Neubauer. It is a brief encounter between men with a passion for engineering: men who use that passion – in both watchmaking and motorsport – in the pursuit of excellence, and who write technological history.
To this day, the two disciplines are united by an obsession and performance.
AN INGENIOUS INVENTION AND A CRAZY IDEA
Albert Pellaton went on to design a pawl winding mechanism for IWC that was named after him. His 85-calibre automatic movement. Unlike conventional winding systems, which functioned only when the rotor was moving in one direction, his mechanism wound in both directions and was a technological edge over the competition in the 1950s and has been continuously improved ever since. Today, it plays an important role in the Ingenieur watch family. The Mercedes-Benz Silver Arrow dominated international motorsport in the 1930s and in 1954/55, thanks not least to its mechanics. By the standards of the time, their contribution was simply remarkable. The Mercedes Silver Arrow's success story has lasted to this day and began with the W25 at the Eifel GP on the Nürburgring in 1934.
It was there that in a cigar-shaped car that developed 354 h.p. and was capable of speeds up to 300 kph. The car had already created a furore in the Mercedes pit before the race even be exactly one kilogram heavier than the permitted maximum weight of 750 kilograms. At this, von Brauchitsch is said to have suggested stripping the white paint to reduce the weight to the permitted limit. And overnight, this is precisely what the mechanics did. This revealed the gleaming aluminium bodywork, which from then on gave the W25 and its successors the name “Silver Arrow” (German: “Silberpfeil”). The legend was born.
THE MERGER OF TWO TECHNOLOGICAL ICONS
In 2013, IWC Schaffhausen brings together the illustrious names “Ingenieur” and “Silberpfeil” in its new Ingenieur Chronograph Silberpfeil. The thing that strikes you most about the chronograph in its stainless-steel case is the design. One of the most conspicuous features is the circular- grained dial in silver (Ref. IW378505) or brown (Ref. IW378511). Circular graining, or “perlage”, is a cloudlike pattern of small overlapping circles that is usually reserved for plates and bridges. Here, it is a tribute to the legendary Mercedes-Benz W25, whose instruments were mounted on a dashboard with a circular-grained surround. and gives the Ingenieur Chronograph Silberpfeil its highquality, technically inspired look. The red elements on the silver-plated or brown dial take up the design of the tachom eter and revolution counter. The date display is integrated into the lower counter, thus maintaining the perfect symmetry of the dial.
TRADITION AND HIGH TECHNOLOGY
best that fine watchmaking currently has to offer. The movement enables stopped hours and minutes to be read off as simply as the time on a subdial, while the central stopwatch hand records short stop times of up to a minute. Used in combination with the tachymeter scale, this provides the speed at which a reference distance of 1,000 metres is completed. Another practical feature for anyone who fre-measuring pit-stop times: simply pressing the reset button causes the chronograph seconds hand to jump to zero and immediately starts another timing sequence. This eliminates the complicated business of successively pressing the stop, reset and start buttons. The further-improved Pellaton winding system builds up a 68-hour power reserve in next to no time. Its automatic double-pawl winding mechanism Albert Pellaton: an enhancement of which the ingenious inventor would wholeheartedly have approved. On top of that, the watch's accuracy is unaffected when the chrono-of the world's leading brands in the luxury watch segment, combining supreme precision with exclusive design.
The Ingenieur Chronograph Silberpfeil has a wristband with a brown leather inlay. This likewise takes us back to the world of motor racing in the 1930s, when sturdy leather straps – on the drivers' overalls as well as in the cockpit and on the car's bonnet – were virtually omnipresent. Unlike those, however, the chronograph's high-quality strap is rubber on the inner surface. In this way, the traditional leather look is combined with the comfort and long service life of rubber. Another option is the stainless-steel bracelet historic Silver Arrow racing car can be found on the case back.
THE ERA OF THE SILVER ARROWS
Between 1934 and 1939, Mercedes-Benz won countless Grand Prix victories and championships with the Silver Arrow. In 1935, Rudolf Caracciola was crowned European champion driving the W25: a feat he repeated with its successor, the W125, in 1937, and in 1938 with the W154. Until 1939, he and the other members of the team, such as Manfred von Brauchitsch and Hermann Lang, dominated international motorsport's premier discipline. And in 1954, Mercedes-Benz celebrated the return of the Silver Arrows to Formula One™ with a one-two victory at the French Grand Prix. The winner, Juan Manuel Fangio, won three more
Grands Prix with his W196 R, and the world championship.
The W196 R dominated the 1955 season too. In the seven of them one-twos, and Juan Manuel Fangio retained his Formula One™ crown. Teammate Stirling Moss became a living legend when he won the 1955 Mille Miglia in a new record time. After this, Mercedes-Benz retired from motorsport to focus on series production. Since 2010, the MERCEDES AMG PETRONAS Formula One™ Team has been vying for points again, and is now supported by its
With a clear focus on technology and development, the Swiss watch manufacturer IWC Schaffhausen has been producing timepieces of lasting value since 1868. The company has gained an international reputation based on a passion for innovative solutions and technical ingenuity. One of the world's leading brands in the luxury watch segment, combining supreme precision with exclusive design.
