IWC Ingenieur Perpetual Calendar Digital Date-Month watch, limited production piece, round titanium aluminide case (47mm diameter, 16mm thickness) with screw-in crown and transparent case back, black rubber strap with textile inlay and titanium buckle, black dial with black/luminous hands and index hour markers, perpetual calendar (with leap year display), large double-digit displays for both the date and month, flyback chronograph stopwatch function (with hours, minutes and seconds), hour and minute counters combined in a totalizer at 12 o?clock, small hacking seconds, 51 jewel Caliber 89802 self-winding mechanical movement with 68 hours of power reserve, scratch-resistant sapphire crystal, water resistant to 120 meters.With the Ingenieur Perpetual Calendar Digital Date-Month, IWC presents its first watch case made of titanium aluminide and reaffirms its reputation as the materials pioneer in the watchmaking industry. Titanium aluminide is used widely in motorsport: the alloy is lighter and more robust than pure titanium. The black parts of the case are made of zirconium oxide, yet another material typically used in Formula One. Modern racing cars have a boost button designed to provide maximum thrust when needed. In the case of the perpetual calendar with its digital date and leap year display, this job is handled by IWC?s revolutionary quick-action switch. Every night, when the date changes, this sophisticated mechanism siphons off a little energy, stores it and then discharges it precisely at the end of the month to rotate the display discs. At the end of the year, no fewer than five display discs need to be advanced synchronously. On New Year?s Eve, thanks to the three semi-transparent totalizers, the entire dial is set in motion. It is a spectacle of technical brilliance that no one who appreciates complex mechanical systems will want to miss. The transparent sapphire-glass back provides an unimpeded view of the IWC-manufactured 89802 calibre, whose rotor resembles the spokes on a light alloy wheel rim.
