IWC Ingenieur Constant-Force Tourbillon Platinum / Ceramic Ref. IW5900-01

With the spectacular Ingenieur Constant-Force Tourbillon in its platinum and ceramic case, IWC now leads the field in the Constructors’ championship of haute horlogerie. It guarantees an extremely precise rate over a period of at least 48 hours. The 94800-calibre basic movement features two barrels, which 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.
