Short answer
IW93829 does not match a reference in IWC's public catalog. IWC codes start with IW and run four or six digits, as in IW3714 or IW371617. A five-digit string such as 93829 reads as a seller SKU. Treat it as a listing code, not a factory model number. Ask the seller one question first: which IWC watch does this copy. The answer sets the case size, movement, and dial layout.
What "first copy" means on these sites
First copy is a seller term, not a grade standard. It sits near the top of the tiers that sellers advertise: AAA, super clone, first copy, 1:1. No trade body defines those labels. The label tracks price band more than build. A watch sold as a first copy should arrive with a decorated automatic movement, a solid link bracelet with screws, and sapphire glass. Verify each item on delivery.
Checks before payment
- Movement name and photo. Ask for the calibre number and a photo of the rotor and balance.
- Case diameter and thickness in millimeters. Compare to the genuine spec sheet.
- Weight in grams on a scale, with a timestamped photo.
- Timegrapher printout. Rate, amplitude, beat error.
- Case back type, screw-down or snap. Water resistance claim in meters or bar.
- Return terms in writing, plus the payment method and who holds the funds.
Movements you will see
Replica IWC chronographs in this size class use the Asian 7750, a Valjoux 7750 pattern with a cam-switching chrono. Copies of the IWC 69370 add decorative plates and rotor engraving. The plates hide the base movement but do not change its rate. Three-hand copies often use a Miyota 9015 or a Seagull ST21. Parts are cheap and available. Service from IWC is not.
Case, glass, and water
Case steel is 316L on most replicas. 904L appears on a few higher-priced copies. Sapphire covers the dial, with anti-reflective coating on one face or both. ISO 22810 sets the test criteria for water-resistant watches, and a replica often ships with no test record. A snap case back and dry gaskets leak. Do not swim with a replica, even when the listing says 50 meters.
Legal status in the US
A counterfeit watch carries a real IWC trademark and logo. Selling or importing one violates US trademark law, and 18 U.S.C. 2320 covers trafficking in counterfeit goods. CBP can seize a shipment at the border. Buyers face fewer charges than sellers, but the parcel can be lost with no refund. Payment through a card network gives a chargeback path. Peer-to-peer transfers do not.
After delivery
Open the parcel on video. Check the serial engraving, the dial printing, and the bracelet screws. Wind the watch and set the time. Run the chronograph start, stop, and reset ten times. Time it against a reference clock over 24 hours. A rate outside 15 seconds per day on a fresh movement points to a problem. IWC will not service the watch, and a local watchmaker may refuse to work on a counterfeit. Resale value is near zero.
