IWC_INGENIEUR CONSTANT FORCE TOURBILLON

HANDOUT - The Ingenieur Constant-Force Tourbillon (Ref. 5900) features an impressive patented constant-force mechanism. IWCs hallmark double moon display also makes its debut in a new design: the surface of the earths satellite is rendered as authentically as possible, so that even tiny craters are visible.
