WATCHMAKER｜IWC Ingenieur Perpetual Calendar: The Legendary Collision of Genta and Gros

The IWC Ingenieur Perpetual Calendar is the first steel watch to ingeniously combine Kurt Klaus's perpetual calendar with the design heritage of Gérald Genta. The integrated steel bracelet offers both the robustness and water resistance of a sports watch. Complementing the grid-patterned dial, the sunburst-finish chronograph subdials and the luminous moon phase display add visual depth while reflecting light. Forty years after Kurt Klaus developed IWC's perpetual calendar watch, this model makes its debut in a sporty iteration with distinctive craftsmanship.
