IWC Ingenieur Automatic 40 QC: the grid dial, the five bezel screws and the integrated bracelet

Watches QC & Legit Check
1

Which Ingenieur are we talking about? Not the older white-dial reference compared in IWC Ingenieur white dial: GEN vs V7F. This thread is the Ingenieur Automatic 40, reference family IW3289. The model facts below come from published hands-on reviews, because the brand’s own page could not be checked; anything we could not confirm is left out.

Why does it need its own thread? Because three details carry the whole design: the grid dial, the five bezel screws and the integrated bracelet. Get those wrong and nothing else matters.

Where do I even start with this one? The dial is so busy that I can’t tell what is a flaw and what is the pattern.

Start with the dial, step by step:

  1. Know the pattern. Reviews describe a grid made of raised and recessed line sections, with the lines offset 90 degrees to each other, and stamped into the dial.
  2. Check the grid is even. The squares should look the same size across the whole dial, with lines running cleanly to the edge and around the markers, not blurred or broken in one area.
  3. Ask for two angles. Because the texture is relief, the light changes it a lot. One straight-on photo and one at a slight angle show whether the pattern is really there or only printed.
  4. Compare like with like. Steel versions come with black, silver or aqua dials, and the titanium version with a grey dial; compare with photos of the same reference and colour.

Verdict first: the bezel screws are the quickest check.

  • Reviews state that five screws secure the round bezel to the case. One review notes that an earlier generation had only holes there; this one has real screws.
  • Check that all five are present, the heads look the same size, and they sit evenly spaced around the bezel.
  • Do not assume a particular slot orientation unless you have compared with photos of the gen of the same reference. I would want to see that before calling anything a flaw.
  • Bezel finish, per review: polished, chamfered sides and a circular-grained top. A uniformly shiny top is worth a question.

Alignment tools help with spacing, but only on a straight-on photo; their limits are in QC alignment tools and apps.

TL;DR: the bracelet finish has to match the dial version.

  • Integrated bracelet with H-shaped links in a three-link layout, following the lines of the case.
  • Per one review, the black and silver steel versions have a fully brushed bracelet, while the aqua version (IW328903) has polished centre links. A polished centre link on a black or silver dial is a mismatch worth asking about.
  • Reviews describe a concealed butterfly clasp, with no micro-adjustment and no quick-release system.
  • The case has crown guards and a screw-down crown.

Reviews keep quoting 40 mm and a short lug to lug. Can the photos confirm those numbers? And what about the movement everyone mentions?

  1. Numbers from reviews: 40 mm diameter and 45.7 mm lug to lug (two reviews agree). Thickness is given as about 10.7 mm in one review and about 10 mm in another.
  2. What photos can do: show proportions roughly. They cannot measure millimetres unless a calliper is in the shot, and even then the angle matters.
  3. Movement, per reviews: calibre 32111, about 120 hours of power reserve, 28,800 vph, behind a solid screwed caseback, with a soft-iron inner case. Water resistance is quoted as 10 bar.
  4. What photos cannot prove: the calibre inside, the soft-iron case, the water resistance or the timekeeping. A solid caseback shows nothing of the movement, so treat any movement claim as unverified.

So what is the checklist? In order:

  1. Right model: Ingenieur Automatic 40 (IW3289), not the older white-dial reference in topic 17.
  2. Grid dial: even raised and recessed grid, lines at 90 degrees, clean around the markers; ask for a straight-on and an angled shot.
  3. Bezel: five screws present, same size, evenly spaced; polished chamfered sides, circular-grained top.
  4. Bracelet: H-links; fully brushed on black and silver steel, polished centre links on the aqua (IW328903); concealed butterfly clasp.
  5. Case: crown guards, screw-down crown; 40 mm and 45.7 mm lug to lug are review figures that photos can only approximate.
  6. Not provable by photos: calibre 32111, power reserve, soft-iron case, water resistance, timekeeping.

Agreed. Dial texture, five even screws, bracelet finish matching the dial version. Everything else is either a review number or invisible in photos.
