New Releases

IWC has introduced the Ingenieur Perpetual Calendar 41 in titanium, combining its integrated-bracelet design with a perpetual calendar for the first time.

IWC Schaffhausen has introduced the Ingenieur Perpetual Calendar 41 (Ref. IW344904) at Watches and Wonders Geneva 2026.

The watch combines a 41mm grade 5 titanium case and integrated titanium bracelet with IWC's perpetual calendar complication. It is the first Ingenieur Perpetual Calendar in titanium, and also IWC's lightest perpetual calendar watch to date.

The model features a matte grey "Grid" dial, a sapphire caseback, and the IWC-manufactured 82600 calibre with a Pellaton winding system and ceramic components. Other features include a crown-adjusted perpetual calendar, a moon phase display, and a 60-hour power reserve.

What We Noticed

What stays with us is seeing the Ingenieur and IWC's perpetual calendar brought together in titanium.

The familiar case, integrated bracelet, and five-screw bezel remain instantly recognisable. This time, they surround a perpetual calendar display with subdials at 3, 6, and 9 o'clock. The matte grey "Grid" dial blends so closely with the titanium case and bracelet that the watch looks almost carved from a single piece of metal.
