Gérald Genta’s integrated design meets Kurt Klaus’ perpetual calendar, in its lightest execution yet.
IWC Schaffhausen continues to expand the modern Ingenieur line by once again pairing the 1970s Gérald Genta-inspired integrated case and bracelet with the crown-operated perpetual calendar developed by Kurt Klaus in the early 1980s. Following the steel version launched last year, this 2026 release introduces a full-titanium construction; meet the Ingenieur Perpetual Calendar 41 in titanium, the lightest perpetual calendar watch currently produced by IWC.
The case measures 41.6mm in diameter and 13.2mm in height, closely mirroring the proportions of the steel reference. Made entirely from grade 5 titanium, the case, bezel, crown protection, and integrated bracelet showcase sandblasted surfaces, satin-finished flanks, and polished bevels. The round bezel is secured by five functional screws, a defining Ingenieur trait since 1976. Water-resistance, aided by a screw-down crown, is 100m.
The dial follows a monochromatic approach, one we favoured upon the introduction of the Titanium IWC Ingenieur Automatic 40 (2023). Finished in matte grey to match the titanium exterior, it features the familiar stamped “Grid” pattern composed of alternating lines and squares. The three calendar subdials are slightly recessed and decorated with circular satin brushing and azurage on their rims, separating the indications. At 3 o’clock is the date, at 9 o’clock the day of the week with the leap year countdown, and at 6 o’clock the month combined with the perpetual moon phase. The moon disc is set against a finely azuraged background and is accurate to one day in 577.5 years. Applied indices and hands are filled with Super-LumiNova, and work well for legibility despite the monochromatic palette.
Powering the watch is the IWC-manufactured calibre 82600, visible through a sapphire caseback. This automatic movement integrates Kurt Klaus’ mechanically programmed perpetual calendar, allowing all indications to be adjusted via the crown. The Pellaton winding system uses ceramic components for high-wear parts such as the automatic wheel and clicks, improving durability and long-term efficiency. Operating at 28,800 vibrations/hour, the movement delivers a 60-hour power reserve and is finished with Geneva stripes, circular graining and blued screws.
The integrated titanium bracelet is secured with a butterfly folding clasp. Price is CHF 41,000. For more information, please visit IWC.com.
