Short answer
"Fake IW329116V6" is a search phrase, not an IWC reference. It joins two parts: IW329116, an IWC reference number in the Aquatimer line, and V6, a version tag used by replica sellers. IWC does not make a "V6". No IWC catalog page lists that suffix.
Read the phrase as: a copy of the IWC Aquatimer Automatic with reference IW329116, sold as a sixth-version replica by a workshop the trade calls V6 or V6F.
What the reference number covers
IWC reference numbers run as IW plus six digits. The 3291 block covers the Aquatimer Automatic. IWC lists a 42 mm steel case, 300 m water resistance and calibre 30120 for models in that block. The final two digits set the dial color, strap or bracelet, and market variant.
There is no public IWC table that maps IW329116 to one dial and strap combination. Ask the seller to name the dial color and the strap or bracelet type in writing. A listing that skips both is incomplete.
What V6 signals in the replica trade
Replica workshops do not print brand names. They use short codes. V6 and V6F appear on listings for IWC, Panerai and Audemars Piguet copies. The code points to the workshop that made the case and hints at the mold version.
A V6 tag is a label, not a grade. Two sellers can use the same label for watches from different batches. Ask for photos of the unit you will receive, not studio renders.
Checks on a replica Aquatimer
- Case diameter: the 3291 measures 42 mm. A copy at 44 mm is a different reference.
- Bezel: it should index in clear steps with no drift between positions.
- Crown: screw-down, with clean thread engagement and no wobble.
- Dial print: the "Aquatimer" and "Automatic" text should sit level, with even stroke weight.
- Lume: charge the markers under light, then compare brightness after 30 minutes.
- Movement: ask for the calibre name and beat rate. The IWC calibre 30120 runs at 4 Hz.
Price and what it reflects
Replica prices for a 42 mm steel dive watch on rubber span a wide band. A low price points to a cheaper movement, a stamped case back, and no water pressure test. Ask what the case is rated for. A 300 m figure on a case back is a print, not a test result.
Open points
No public register lists replica batch numbers. Nobody can confirm that V6 means one factory, one year or one mold. Treat the tag as a seller claim. Get the return policy and the shipping terms in writing before you pay.
