Short answer
A replica IW323727 is a copy of an IWC watch sold under that reference number. Copies run from about $80 to $550. Price tracks the movement and the case finish, not the name on the dial. IWC does not list this reference in its current catalog. Published specs for the genuine watch are thin, so compare any copy against photos of the real piece instead of the seller's text.
How to read the reference
IWC writes references as IW plus six digits. The first four digits name the model family. The last two name the case metal, dial color, and bracelet. IW323727 is one variant of the IW3237 model. Many sellers use the long number for any copy they stock, so the metal in the listing may not match the variant code. Ask for the caseback photo to confirm what you get.
Movement tiers
- Entry, $80 to $150: quartz or a low-grade automatic. The second hand ticks or stutters.
- Mid, $160 to $300: Seiko NH35A or Miyota 9015. Hacking, hand winding, about 40 hours of power reserve.
- Top, $300 to $550: Asian ETA 2824 clone or Sea-Gull ST2130. Parts are standard, so a local watchmaker can service it.
Ask for the movement name in writing. A seller who answers with "imported automatic" is selling a $12 movement in a $200 case.
Case and dial checks
- Case metal: 316L steel on most copies, 904L on the top tier. A 316L copy feels light for its size.
- Crown and pushers: the crown should thread with no grit. Backlash in a screw-down crown means worn threads.
- Dial: applied indices sit level, printed text stays sharp at 3x zoom, no dust under the crystal.
- Lume: C3 or BGW9 in top tiers holds a glow for hours. Cheap copies fade in 20 minutes.
- Bracelet: end links sit flush against the case, no rattle at the clasp, screws instead of push pins.
Water resistance
Replica gaskets are not pressure tested at the factory. A copy sold as "200m" can leak at the crown the first time it sees a pool. Do not swim with a copy. If you want water resistance, a watchmaker charges $40 to $80 for new gaskets and a pressure test. No test, no swimming.
Service, parts, and resale
NH35A and 9015 movements service for $60 to $120. ETA 2824 clones take standard Swiss parts. Resale is weak on every tier. Expect to recover about half of what you paid, and less without service records.
Legal status in the United States
U.S. Customs can seize and destroy counterfeit shipments. Selling a counterfeit watch is a trademark violation under the Lanham Act. Buying one copy for personal use is a different act from selling, but the parcel can still stop at the border and get destroyed.
Checklist before payment
- Ask for seller photos of the actual watch. Catalog renders hide flaws.
- Get the movement name and a caseback photo.
- Confirm a return window of 14 days or more.
- Pay with a card, or a method that allows a chargeback.
- Compare the date window and dial text against a genuine photo at 3x zoom.
