Short answer
IW323722 is an IWC reference inside the Ingenieur Automatic group. The 3237 block of IWC numbers covers that line. Case size, dial color and bracelet finish change between numbers in the block, so confirm the exact spec for IW323722 with IWC before you buy or sell one. Replicas of this reference exist. Most are built in a few workshops in Guangzhou and sold through dealers who reuse the same photo sets. A replica does not match IWC case tolerances or movement finishing. Treat any "1:1" or "super clone" label as sales copy, not a spec.
What the genuine watch carries
The Ingenieur Automatic line uses a steel case with an integrated bracelet, a screw-down crown and a soft iron inner cage for magnetic shielding. The 3237 group runs a self-winding movement in the IWC 30110 family, an ETA 2892 base with IWC finishing and regulation. Case backs are engraved, not printed. Crystals carry an anti-reflective coating on both faces on most versions in the group. If a seller cannot name the caliber, the case diameter or the bracelet taper, stop there.
Checkpoints
- Case back engraving. Genuine text sits in a cut recess with crisp edges. Fakes show shallow laser etching and soft edges.
- Movement. Ask for a photo of the rotor and the balance. A 30110 has a specific bridge shape and a regulated balance with a swan neck. Asian clones from the 2892 family look close from 30 cm and wrong under a loupe.
- Soft iron cage. The inner case on the real watch adds mass. A fake case weighs less and feels light in the hand.
- Crown threads. Genuine crowns engage in under two turns and seat flush. Fakes feel gritty and sit proud of the case.
- Bracelet fit. End links meet the case with no gap and no step. Pins and screws on the real bracelet are finished on both ends.
- Dial print. Check the minute track and the logo under 10x. Fake print shows ink spread and uneven spacing.
- Serial and paperwork. Cross-check the case number against the warranty card and the IWC service record.
Price reality
Replica sellers ask USD 300 to 600 for this reference. That price buys a generic bracelet, a stock clone movement and a printed case back. The genuine steel Ingenieur Automatic trades on the secondary market in the low to mid four figures, and price moves with box, papers and service history. A genuine watch offered far below that band is a warning sign, not a bargain.
Before you pay
- Request dated photos of the case back, the crown side and the movement.
- Ask for a video of the seconds hand sweep and the date change.
- Meet at a watchmaker for a movement check on any private sale above USD 1,000. A case back opening takes minutes and settles the question.
