IWC released the Ingenieur Automatic 35 Pool this week, a new dial colour for the 35mm Ingenieur that the brand is calling aquatic, and the name does most of the explaining. The dial is a light blue-green, somewhere between turquoise and the shade of a well-lit swimming pool on a clear day, and it is the most visually striking thing IWC has done with the Ingenieur since they brought the Gérald Genta design back in 2023.
The watch itself is not new. The 35mm Ingenieur launched in 2025 as a more compact alternative to the 40mm version that kicked off the modern collection, and it has been available in blue, silver and black since then. The Pool dial is a sixth reference for the 35mm lineup, reference IW324902, and everything else about the watch stays exactly the same. The case is stainless steel at 35mm wide and 9.4mm thick, which is slim enough that the watch sits flat and comfortable on the wrist without the bulk that often comes with integrated bracelet designs. Water resistance is 100 metres.
The case and bracelet carry the same finishing as the rest of the 35mm family, brushed surfaces across the main panels with polished bevels on the case edges, crown guards and the central H-links of the bracelet, giving the whole watch a clean contrast between matte and bright. The bezel is secured by five functional screws, a design detail carried over directly from Genta’s 1976 Ingenieur SL, and the butterfly folding clasp keeps the underside of the bracelet neat.
The dial runs the Ingenieur’s signature grid pattern, small stamped blocks of alternating vertical and horizontal lines that give the surface real texture and depth, particularly in how it catches and scatters light at different angles. In direct sunlight the Pool colour reads bright and energetic, and in softer light it pulls toward a richer blue. Rhodium-plated hands and hour markers are filled with Super-LumiNova, and the date sits in a framed window at 3 o’clock. IWC’s lightning bolt logo appears at 6 o’clock, a reference to the original Ingenieur’s anti-magnetic purpose.
The movement is the IWC Calibre 47110, visible through a sapphire display caseback, which the 40mm version does not have. It runs at 28,800 beats per hour with a 42-hour power reserve and is decorated with circular graining and Geneva stripes, with a gold-plated rotor. The architecture is based on the Cartier 1847 MC, a fact that comes up regularly in watch circles, though the finishing IWC applies is well above what you would usually see on a base movement.
Actor Andrew Garfield was spotted wearing the Pool dial at Wimbledon before the official release date, turning up in a turquoise outfit that matched the dial closely enough to suggest it was not accidental. IWC has form for this kind of preview, with Ed Sheeran having worn the black ceramic Ingenieur on The Tonight Show ahead of its reveal at Watches and Wonders last year.
The Ingenieur Automatic 35 Pool is part of the permanent collection and is priced at USD $11,200, CHF 10,500 and EUR 11,300, in line with the other 35mm steel references.
