Quick answer
Replica IW323746 is a copy of an IWC Ingenieur Automatic. Listings that use this number point to the Ingenieur Automatic family: integrated bracelet, crown at 3 o'clock, date at 3 o'clock, and a soft-iron inner case for magnetic protection. IWC does not show IW323746 on its current product pages, so treat the number as a seller label. Copies sell for about $70 to $400. The movement, the case material, and the dial printing set the price, not the reference number.
What the number covers
IWC reference numbers start with IW and six digits. The first four digits group the model family. IW3237 sits in the Ingenieur Automatic range. Case sizes in that range are 40 mm and 42 mm depending on the reference. Ask the seller to measure the case across the back, not the bezel, and to send the figure in millimeters.
Price tiers
- $60 to $120: quartz or a low-grade automatic, mineral glass, folded bracelet, stamped clasp.
- $150 to $350: Miyota 9015 or Seiko NH35 inside, sapphire crystal, 316L steel case, solid end links.
- $350 to $700: decorated rotor, tighter dial printing, anti-reflective coating, thicker bracelet links.
A genuine Ingenieur Automatic uses an in-house IWC movement. No copy at any price carries that caliber. Sellers who advertise a "1:1 clone 80110" are describing a Chinese movement with a decorated bridge.
Movement facts
The Miyota 9015 runs at 28,800 vibrations per hour, has 24 jewels, and measures 3.9 mm thick. The Seiko NH35 runs at 21,600 vph with 24 jewels. Both are serviceable and both appear in this price band. Accuracy for either sits near plus or minus 10 to 20 seconds a day in normal use.
What to inspect on arrival
- Case diameter and thickness against the number the seller quoted.
- Dial text: letter spacing, font weight, and the position of the date window.
- Bracelet fit: the gap between the end link and the case.
- Crystal: anti-reflective coating on the inside face.
- Crown engraving and thread feel.
- Weight on a kitchen scale, compared with the seller's own figure.
Legal position in the United States
Counterfeit goods cannot be imported into the United States. 19 U.S.C. § 1526 lets U.S. Customs and Border Protection seize merchandise that carries a counterfeit trademark. A listing that says "replica" or "first copy" does not change that. Buyers have lost shipments at the border and have no refund path for seized goods.
Service and long-term cost
Ask for a gasket set with the watch. Water resistance on a copy is a claim, not a test result. Have a local watchmaker pressure-test the case before wearing it near water. Movement replacement, not repair, is the common path when a copy stops. Budget $40 to $120 for that work.
Seller checks
- Photos of the exact watch, with a handwritten date card in frame.
- A stated return window of at least 7 days.
- Payment through a method with chargeback rights.
- Written case size and movement model before payment.
