41IW3211 is a seller SKU for a replica of the IWC Ingenieur Automatic 40. It is not an IWC reference number. The "41" matches a 41 mm case. The genuine watch measures 40 mm across. That 1 mm gap is the first item to confirm before payment.

Genuine specs to compare
IWC lists the Ingenieur Automatic 40 (ref. IW3289) at 40 mm diameter, 10.8 mm height and 100 m water resistance. Caliber 32111 runs at 28,800 vph with a 120-hour power reserve. The bracelet is integrated, with an H-link pattern and a butterfly clasp. The bezel carries five recesses, a detail from Gérald Genta's 1976 Ingenieur SL, ref. 1832.
Six checks before you pay
- Case height from a caliper photo. Replicas of this model land at 11.5 mm to 12 mm. Genuine is 10.8 mm.
- Bezel recesses. Count five, check even spacing and clean inner edges.
- End links. They should meet the case with no step and no gap at the lugs.
- Movement name plus a photo of the rotor. "Clone 32111" is a sales line. Miyota 9015 and 2824 patterns also appear in this case.
- Crystal. Genuine sapphire has anti-reflective coating. A strong blue tint points to a coated mineral glass or a single-side coat.
- Weight on a scale. Ask for a photo with the bracelet sized. A light result points to a hollow bracelet.
Water resistance
A 100 m stamp on a replica is a claim, not a test result. ISO 22810 defines the test method and marking rules for water-resistant watches. No replica seller ships that paperwork. Do not swim with a fake unless a watchmaker has pressure-tested it.
Price and risk
Listings sit in the low hundreds of dollars. The genuine watch retails near $12,000. A replica carries no IWC warranty, no service parts and no resale value. US Customs can seize counterfeit imports, and the shipment is lost with no refund path.
