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 or brown. Circular graining, or “perlage”, is a cloud- like 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. A high-quality IWC Caliber C.89361 movement was fitted in the 45 Milimeters stainless steel case and the production has been limited to 1’000 units. The watch on offer is one of this and comes in its original box with all original papers and a proof of the last service, done in 2016. It is in good condition, showing signs of wear.
