IWC Ingenieur Perpetual Calendar 41 (Ref. IW344903)

Introducing the Ingenieur Perpetual Calendar 41, the first stainless steel model to combine Kurt Klaus’ perpetual calendar with the Gérald Genta-derived Ingenieur design. The integrated bracelet execution in stainless steel delivers the robustness and waterproofing of a sports watch. Sunray counters and an azurage-finish moon phase disc complement the grid-patterned dial, providing additional visual depth and reflect the light. #IWCwatches | #IWCingenieur | #FormUndTechnik | #WatchesAndWonders2025
