In the year of Ingenieur watches, IWC launched several new Ingenieur models. Some of them deserve a leading position in the haute horlogerie Constructors’ Championship; some new pieces are just attractive, while the new Ingenieur Chronograph Silberpfeil is a little bit of both.
This newcomer is a tribute to the legendary Mercedes-Benz racing car – the Mercedes-Benz Silver Arrow W25, whose dashboard had a stainless steel surround with a matching circular-grain decoration. The word “Silberpfeil” is actually a German word for Silver Arrow. The Silberpfeil series was very successful on the racing track during 1934 and 1939, having won numerous Grand Prixes and other championship victories.
While the design of the new watch is inspired by the historic racing car, its heart is a highly efficient IWC-in-house-made movement. Ingenieur Chronograph Silberpfeil watch is powered by the caliber 89361 – the one of the best that fine watchmaking at the moment has to offer. The mechanical chronograph movement provides full 68 hours of power reserve when fully wound. The self-winding mechanism is built on 38 jewels and beats at the frequency of 28,800 vibrations per hour (4 Hz).
The flyback chronograph allows reading of stopped hours and minutes as simply as the time on a separate sub-dial. The chrono counter is located on the upper part of the dial, at the 12 o’clock position, while the small seconds sub-dial is placed on the opposite side, at the 6 o’clock position. A small date window is situated in a small seconds counter
The central stopwatch hand records short stopped times of up to a minute. Used in combination with the tachymeter scale, this functionality provides the speed at which a reference distance of 1,000 meters has been completed.
The automatic double-pawl winding mechanism of the watch is 30 percent more efficient than the one designed by Albert Pellaton. Further, its accuracy is unaffected when the chronograph is running or when the flyback function is activated.
The new Ingenieur Chronograph Silberpfeil immediately catches the glance by its circular-grained dial, presented either in silver or in brown color (their referent numbers are IW378505 and IW378511). A circular grain pattern, also known as “perlage”, represents a cloud-like pattern of tiny overlapping circles which are often used on plates and bridges.
The watch is housed in a masculine stainless steel case with the diameter of 45mm and the thickness of 15mm. Its case is protected with a flat sapphire glass with antireflective coating on both sides. The water resistance is assured down to 120 meters (approximately 400 feet). The case back boasts an attractive engraving of a nicely designed Mercedes-Benz Silver Arrow racing car.
IWC Ingenieur Chronograph Silberpfeil Watch is attached to a specially designed wristband with a brown leather inlay. Actually the wristlet has been inspired by the sturdy leather straps that were very popular in the 1930s.
Both versions of the new Ingenieur Chronograph Silberpfeil will be produced as limited editions of 1000 specimens of each. The retail price is $13,100 per piece.
