Short answer
A fake IW323774 is a replica of an IWC watch sold under the reference IW323774. IWC is a Swiss maker based in Schaffhausen. The company formats most references as IW plus six digits. The last two digits mark a case, dial, or strap variant. So IW323774 points to the same base model as the other IW3237x numbers, with a different finish or band.
IWC does not publish a lookup that maps every full reference to a market name. Listings that call IW323774 by a specific model name can be wrong. Confirm the model name and the case size with an authorized dealer before you buy.
What "first copy" means
"First copy" is trade language for a replica built to sit close to the original in size, weight, and finish. Sellers split these into grades. The grade decides the parts inside.
- Low grade: quartz movement, plated brass or low-grade steel case, mineral glass, printed dial. Case weight runs 25 to 40 grams under the original.
- Mid grade: Japanese automatic, often a Miyota 9015 or 82 series, 316L steel case, sapphire glass, 21,600 beats per hour.
- High grade: Swiss ETA 2824-2, Sellita SW200, or a close clone, 28,800 beats per hour, 38 to 42 hours of power reserve, sapphire with anti-reflective coating on both sides.
Ask for the movement name in writing. A seller who cannot name it is selling the low grade.
Checks on a replica IW323774
- Measure the case. Diameter and thickness in millimeters should match the maker spec sheet. A 1 mm gap shows on the wrist.
- Check the beat rate. Put the watch on a timegrapher or a phone app. 28,800 vph reads as 8 beats per second. 21,600 reads as 6.
- Read the dial print. Logo, index markers, and minute track should sit at even spacing with no ink bleed. Compare font weight with photos from the maker.
- Turn the crown. Threads should engage in half a turn. Grit or wobble means a cut thread.
- Check the date window. The disc should center in the aperture at midnight, not drift.
- Read the caseback. Reference and serial engraving should be crisp and even in depth.
- Weigh the watch. Grams catch plated cases fast.
- Inspect the bracelet. Solid end links, screw pins, and a firm clasp. Folded links and push pins are the low grade.
Price bands in the US
Low grade: $40 to $90. Mid grade: $150 to $400. High grade with a Swiss or clone Swiss movement: $400 to $900. Above $1,200 a replica sits in the range of a used original, so compare both sides.
Legal note
US law bars the import and sale of counterfeit goods. Customs and Border Protection can seize a shipment and destroy it. Federal statute 18 U.S.C. 2320 carries criminal penalties for trafficking. Buy with that in mind.
