The IWC Ingenieur Automatic 40 IW328903 brings contemporary engineering and refined finishing to one of watchmaking’s most recognizable integrated-bracelet designs. This 2023 model features a striking turquoise “grid” dial housed in a perfectly balanced 40mm stainless steel case, paired with an integrated H-link steel bracelet for a seamless, athletic profile.

Originally inspired by the bold industrial aesthetic introduced in the 1970s, this modern Ingenieur retains its distinctive design language while incorporating advanced movement technology and enhanced ergonomics for superior daily wear.

Design & Wearability

The 40mm stainless steel case combines brushed and polished finishes for dynamic contrast. Its integrated bracelet flows naturally from the case, offering a balanced, ergonomic fit even on slimmer wrists.

The bezel is secured with five functional screws, reinforcing the industrial-inspired aesthetic. The turquoise dial features a structured grid pattern that reflects light beautifully, while luminous hands and markers ensure excellent legibility in all conditions.
