The Ingenieur Chronograph Edition “Cancellara” (Ref. IW380704) is limited to 77 watches (7 is Fabian Cancellara’s favourite number). The watch is powered by the IWC-manufactured 69370-calibre movement with a bidirectional pawl-winding system and a 46-hour power reserve. The satin-finished case is made from titanium, a particularly light and robust material. The dial is silver-plated while the tachymeter scale and subdials are galvanized in black. Red elements on the hands provide an additional colourful highlight. The black embossed strap is made from a special type of rubber that is highly resistant to heat and the elements. A further highlight can be found on the rear side of the watch: the glass back cover provides a view of the 69370-calibre movement and is printed with a spoke design that is reminiscent of a racing bike. The limited-edition numbering underscores the exclusivity of this special model, available from the beginning of July 2017 in IWC boutiques.
