IWC Unveils 35mm Ingenieur Pool Dial Watch With 42-Hour Caliber 47110

Q: Did IWC trade the Ingenieur's anti-magnetic soul for a view of its Cartier-based movement?

Yes — on the 35mm Ingenieur, IWC gave up the model’s traditional anti-magnetic architecture in exchange for a slimmer case and an exhibition back showing the movement. That matters because the Ingenieur’s identity was built on anti-magnetism. Since 1955, the line has been associated with a soft-iron inner case, essentially a Faraday cage, protecting the movement from magnetic fields. The current 40mm Ingenieur Automatic still preserves that formula with a solid caseback and magnetic shielding. The new Ingenieur Automatic 35 Pool Blue does not. To keep the watch at 9.4mm thick and add a sapphire display back, IWC omitted the soft-iron inner case used in the larger model. So this 35mm version loses the historic anti-magnetic protection that defined the Ingenieur name. What buyers see instead is the Caliber 47110, IWC’s in-house automatic movement as branded by the company, but one widely described as derived from Cartier’s 1847 MC architecture within the Richemont group. IWC has decorated it with Geneva stripes, circular graining and a gold-plated rotor, making the display back part of the appeal. So the trade-off is real: the 35mm Pool Blue prioritizes wearability, thinness and movement visibility over the Ingenieur’s original technical calling card. For purists, that is a meaningful shift. For buyers drawn to compact luxury sports watches, the open-back execution may be a worthwhile compromise.

IWC added a new 35mm Ingenieur Automatic in a bright Pool aquamarine dial, expanding the Gérald Genta-inspired line with a summer-focused steel model.
Caliber 47110 powers the watch with a 42-hour reserve and hacking seconds, while an openworked caseback reveals polished, brushed and Côtes de Genève finishing.
The display back comes with a trade-off: IWC dropped the traditional soft-iron inner case, sacrificing the Ingenieur’s historic anti-magnetic shielding to keep thickness to 9.4mm.
The watch keeps a 100-meter water-resistance rating and integrated bracelet, extending a collection that began as a 1955 anti-magnetic tool watch and was reshaped by the 1976 Ingenieur SL.
