Short answer
Replica IW321846 is an unofficial copy of an IWC watch that carries reference 321846. Public IWC catalog data for this exact reference is thin, so confirm the original model with IWC or an authorized dealer before you trust any spec sheet. Treat every listing as unverified until you see photos of the actual unit.
Start with the reference
IWC engraves the reference number on the case back, between the lugs, or in both places. Ask the seller for a clear photo of that engraving on the replica. If the number is missing, stamped on a sticker, or differs by one digit, you cannot confirm which watch the copy imitates. Reference errors are frequent in listings, and a wrong number changes the case size, the dial layout, and the movement.
Price bands
- USD 70 to 150: plated cases, quartz or low-grade automatic movements, printed dials.
- USD 180 to 350: 316L stainless steel, sapphire crystal, Seiko NH35 or Miyota 8215 inside.
- USD 400 and up: clone ETA 2824-2 or Miyota 9015, applied markers, better bracelet finishing.
Ask what the price includes. Shipping, customs fees, and a spare strap often sit outside the quoted figure.
Movement
Ask for the exact caliber, then ask for a video with the seconds hand running and the crown pulled to the setting position. A Miyota 8215 stutters when the seconds hand starts. A 2824 clone hacks and winds in both directions. If the watch has a chronograph, the sub-dial at 9 o'clock should sweep, not tick once per second.
Case, crystal, dial
- Weight in grams. Ask for a scale photo. Plated cases read low.
- Crystal clarity at an angle. Sapphire stays clear. Mineral shows haze.
- Date window edge. Sharp cut corners point to a stamped dial.
- Lume. Ask for a dark photo after 30 seconds under a lamp.
- End link fit at the lugs. Gaps of 1 mm or more show on the wrist.
Questions to send before paying
- Which reference does this unit copy, and where is the engraving?
- What movement is inside, and can you send a running video?
- What is the case material and the measured case diameter?
- Do you have QC photos of this exact unit, not a stock image?
- What is the return policy, and who pays return shipping?
Legal and payment risk
US Customs and Border Protection can seize shipments of counterfeit goods, and US trademark law bars their sale. Sellers rarely offer refunds for seized parcels. Pay with a method that allows a chargeback, keep the listing text, and note that a replica is not a genuine IWC and holds no manufacturer warranty or service support.
Bottom line
Confirm the reference first. Then quiz the seller on movement, case material, and unit photos. A seller who answers with specifics is a better signal than any photo on a product page.
