The Short Version
A single new dial colour changes the character of a watch entirely.
The Ingenieur Automatic 35 in Pool (Ref. IW324902) is precisely that kind of update: the architecture stays untouched, the proportions remain the same 35 mm by 9.4 mm silhouette that made the compact Ingenieur persuasive from the moment it arrived. What changes is the mood. The Pool shade, described by IWC Schaffhausen Creative Director Christian Knoop as a “fresh, radiant aquatic shade that feels made for summer”, shifts the dial from the collected restraint of the silver or black variants into something lighter and more expressive. For GCC collectors who wear sport-luxury pieces through an extended summer calendar, the timing is deliberate.
Design & Identity
The colour is new; the logic behind it is fifty years old.
Gérald Genta conceived the Ingenieur SL in 1976 with an integrated bracelet and a dial architecture built around graphic structure rather than ornamentation. That geometry survives intact in the Ingenieur Automatic 35. The signature “Grid” pattern of small lines and squares gives the Pool dial a three-dimensional quality that plain-coloured dials rarely achieve: the aquatic shade shifts between pale and saturated depending on the angle of light, which the mixed finishing only amplifies.
Surfaces and Finishing
Both the case and bezel alternate between satin-finished and polished surfaces, while the bracelet reverses the relationship — polished centre links running against satin-finished H-links. The result is a watch that reads differently at midday Gulf sun and at evening. The five functional screws securing the bezel to the case ring are not decorative; they are a defining Ingenieur design code carried forward from Genta’s original brief.
Legibility and Wrist Presence
Rhodium-plated hands and applied indices filled with Super-LumiNova provide clear contrast against the Pool ground, maintaining legibility in low light without disrupting the dial’s daytime tone. The “Probus Scafusia” engraving on the crown connects the piece to IWC’s manufacturing identity in Schaffhausen.
Movement & Materials
The sapphire crystal caseback is worth opening for.
Calibre 47110 beats at 28,800 vph with 23 jewels and a 42-hour power reserve. The movement is decorated with circular graining and Geneva stripes, and carries a gold-plated oscillating mass. None of that is visible in daily wear, but it informs the sense of value that separates an integrated-bracelet sports watch at this level from its more functional counterparts. The case, bracelet, and bezel are all stainless steel, water-resistant to 10 bar, and protected by antireflective sapphire on both crystal faces.
Who This Watch Is For
The 35 mm Ingenieur sits at an intersection that few sport-luxury watches occupy cleanly.
Its dimensions make it genuinely versatile across wrist sizes without reducing it to a category label. The Pool dial adds a chromatic option for those who find the black and silver references too measured and the gold edition too formal. At Watches and Wonders, IWC already expanded the 35 mm line with a diamond-set 18-karat 5N gold bezel reference and a deep blue dial. The Pool variant now makes six references in total — a collection wide enough to address distinct collector profiles without duplicating intent across references.
Final Verdict
The Pool dial does not reinvent the Ingenieur Automatic 35 — it was not designed to.
What it does is extend the collection’s tonal range into something that reads as genuinely seasonal without sacrificing the structural authority that makes the Genta-derived design worth owning in the first place. For a collector in the GCC who already holds a more restrained variant, this is a second-piece argument. For a buyer encountering the 35 mm Ingenieur for the first time, Pool offers the most distinctive entry point in the range.

Frequently Asked Questions
What is the reference number and case size of the IWC Ingenieur Automatic 35 with the Pool dial?
The watch carries reference IW324902 and measures 35 millimetres in diameter with a case height of 9.4 mm. The case and integrated bracelet are crafted in stainless steel.
What movement powers the Ingenieur Automatic 35 Ref. IW324902?
The watch is powered by IWC Calibre 47110, an automatic movement beating at 28,800 vph with 23 jewels and a 42-hour power reserve. It is visible through a sapphire crystal caseback and is decorated with circular graining and Geneva stripes.
Who designed the original Ingenieur that inspired this model?
The Ingenieur SL Reference 1832, the design ancestor of today's Ingenieur Automatic 35, was created in 1976 by Gérald Genta, the legendary Geneva artist and watch designer. IWC revived his integrated-bracelet design in 2023 and has expanded it into a six-model 35 mm collection.
How many models now exist in the Ingenieur Automatic 35 collection?
With the addition of the Pool-dial variant, the 35 mm collection spans six references: silver-plated dial, black dial, 18-karat 5N gold with gold-coloured dial, Pool-coloured dial, a deep blue dial, and a diamond-set 18-karat 5N gold bezel edition.
Is the Ingenieur Automatic 35 Pool dial suitable as an everyday watch for GCC summers?
The watch is water-resistant to 10 bar and features an antireflective sapphire crystal on both sides, making it well-suited to warm-weather wear. IWC Creative Director Christian Knoop specifically described the Pool colour as 'a fresh, radiant aquatic shade that feels made for summer.'
