Official images: what the IW344903 looks like
IWC’s official IW344903 product page shows the stainless-steel watch with its blue dial and integrated bracelet. The manufacturer’s 1 April 2025 launch release identifies it as the first stainless-steel Ingenieur to combine the Gérald Genta-inspired design with a perpetual calendar developed by Kurt Klaus.
IWC describes satin-finished and polished surfaces on the case, bezel and bracelet, a blue dial with the Ingenieur’s characteristic Grid pattern, and rhodium-plated hands and markers filled with Super-LumiNova. The sapphire display back reveals the movement. The bezel is secured by five functional screws; the bracelet attaches at the middle links and closes with a butterfly clasp. These are the manufacturer’s descriptions, not independent observations from handling the watch.

The precise 41.6 mm diameter and 13.3 mm height are published specifications, not a wrist-fit assessment. IWC’s launch release uses a nominal 41 mm description in its text; the product page gives the more precise 41.6 mm figure.
What the perpetual calendar displays
IWC lists indications for the date, day, month, leap year and perpetual moon phase. The calendar is arranged across three subdials: date and day have their own displays, while the 6 o’clock subdial combines month and moon phase. According to IWC’s launch release, the calendar automatically inserts February 29 in a leap year.

What the published specifications do—and do not—tell you
The listed dimensions, movement figures and water resistance describe IWC’s stated specifications. They do not establish how the 41.6 mm case wears on a particular wrist, real-world accuracy, durability or service needs. No independent comparative or hands-on testing is represented here.
IWC says its standard international limited warranty can be extended from two years to eight by registering through My IWC Care while the original warranty remains active. Warranty terms and territorial application should be checked with IWC for the buyer’s market.
