The Cheap IWC Ingenieur Constant-Force Tourbillon Watch Replica revolves around its own axis once every 60 seconds to offset the influence of gravity on any positional error in the balance and its adverse effect on the rate. Down in the depths of the tourbillon we see the constant-force mechanism, the true heart of the watch. This intricate assembly allows the escapement to be uncoupled from the gear train, which keeps the amplitude of the balance – and thus the watch’s rate – virtually constant.
IWC Ingenieur Replica IW590001 in a platinum and ceramic case. Positioned at “9 o’clock”, the impressive constant-force tourbillon provides a fascinating view of its layered construction. Connoisseurs of precision mechanics will particularly enjoy watching the complex interaction of the springs, wheels and pallets. The striking black tourbillon bridge is calibrated to facilitate reading off the seconds and, like the black screws, underscores the dial’s high-tech look. As a captivating contrast to this we see the delicate, gold-coloured Glucydur beryllium alloy balance with its high-precision adjustment cam on the balance arms.
94800-calibre basic movement was developed entirely internally by IWC. It 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.
