IWC Ingenieur Constant Force Tourbillon watch, limited production piece, round platinum/black ceramic case (46mm diameter, 14mm thickness) with screw-in crown and transparent case back, black alligator strap with platinum buckle, black dial with black/luminous hands and index hour markers, perpetual moon phase display (with double moon phases for the northern and southern hemispheres and countdown display showing phases until next full moon), power reserve display, tourbillon with integrated constant-force mechanism, 43 jewel Caliber 94800 manual-winding mechanical movement with 96 hours of power reserve, scratch-resistant sapphire crystal, water resistant to 120 meters.With the spectacular Ingenieur Constant-Force Tourbillon in its platinum and ceramic case, IWC still leads the field in the Constructors? Championship of Haute Horlogerie. This precision machine?s patented constant-force mechanism is integrated in a tourbillon and ensures that the amplitude of the balance remains almost constant. It guarantees an extremely precise rate over a period of at least 48 hours. The newly developed 94800-calibre basic movement features two barrels that provide the energy for the higher torque required to drive the constant-force tourbillon. It also provides the moon phase module with the necessary power. The double moon display depicts the surface of the earth?s only natural satellite so realistically that even tiny craters can be recognized. The countdown scale shows the number of days remaining until the next full moon. The power reserve display between ?4? and ?5 o?clock? indicates the energy remaining in the mainspring. The design on the movement side, visible through the transparent sapphire-glass back, was inspired by a sports car?s engine block. Perforations provide a clear view of the intermeshing gears: performance engineering for purists.
