The IWC Ingenieur Automatic 35 IW324902 brings a fresh, warm-weather energy to one of horology’s most recognisable integrated-bracelet sports watches. Scaled down to a wearable 35mm stainless steel case, this reference stays faithful to Gérald Genta’s 1976 Ingenieur SL design while introducing a striking new dial colour called “Pool” — a light aqua-turquoise shade that shifts between soft and vivid blue tones depending on the light.

The signature Ingenieur “Grid” dial pattern is instantly recognisable, its negative-relief lines and squares giving the dial genuine depth and texture. Rhodium-plated hour and minute hands, along with hand-applied indices filled with Super-LumiNova, sit against a snailed peripheral track for excellent legibility. A framed date window at 3 o’clock and the brand’s lightning-bolt logo at 6 o’clock complete a dial that balances technical character with everyday wearability.

True to the Ingenieur’s design DNA, the bezel is secured to the case by five functional screws and finished with a satin surface and polished outer edge. The integrated stainless steel bracelet uses distinctive H-shaped centre links, alternating satin and polished surfaces that catch the light beautifully on the wrist, and closes with a comfortable butterfly folding clasp.

Flip the watch over and a sapphire exhibition caseback reveals the automatic Calibre 47110, decorated with circular graining and Geneva stripes and fitted with a gold-plated oscillating weight. With a 42-hour power reserve and 100 metres of water resistance, this is a genuine everyday luxury sports watch — equally suited to the office, travel or a day by the water.

Whether you’re building on an existing Ingenieur collection or looking for a distinctive, more compact alternative to the larger 40mm and 42mm models, the IW324902 offers a rare combination of heritage design, fine finishing and modern colour in a proportion that suits both men and women.
