Buy the seller first and the version second. On a fake IW328083 v6, the dealer's quality control process decides more about what lands on your wrist than the version number in the listing. Ask for dated, close-up photos of the exact watch that will ship, compare its case size and dial layout against IWC's published Portofino specifications, and pay through a method you can reverse. If the seller cannot show the actual unit, or answers questions about the movement with a stock photo, that is the whole answer. The "v6" tag is a factory and community label, not a graded standard, so treat it as a starting point for questions rather than proof of quality.
Fake IW328083V10 Watch Guide: Identifying and Avoiding Fakes
What the v6 label actually means
Replica factories revise popular models in batches and the market numbers those batches informally. A sixth revision usually signals that earlier complaints were addressed: dial printing, hand shape, crown profile, caseback engraving, strap hardware, or a movement swap. None of that is regulated, and two sellers can list the same "v6" while sourcing from different workshops. The label tells you a model has been iterated, not that the iteration succeeded. Your job is to confirm which details changed in this batch and whether they match the genuine reference you are comparing against.
What to check before you pay
Case, dial, and hands
Start with proportions. A Portofino-style dress case lives or dies on thickness and lug curve, and a replica that is 1.5 mm too thick will sit wrong on the wrist no matter how good the dial looks. Check the dial finish under raking light, since sunburst and lacquer effects are where cheap versions fall apart. Look at applied indices for level seating, date window alignment, and the printing weight on the brand text. Hands should be flat, cleanly cut, and correctly sized, with no tool marks on the pinion.
Movement
Ask which movement is inside and then verify it. A chronograph build based on a Valjoux 7750 derivative will show wider subdial spacing than the genuine in-house layout, which is one of the easiest tells to spot in photos. A time-only build often runs a Sellita or Miyota derivative. Request a short video with the crown pulled and the chronograph started and reset, so you can hear the rotor and see whether the reset snaps to zero.
Crystal, caseback, and water resistance
Confirm sapphire rather than mineral glass, and check for anti-reflective coating on the underside. Caseback engraving should be crisp and shallow, not sandblasted blur. Treat any water resistance figure as marketing until proven, and keep a replica away from swimming regardless of what the listing claims.
Strap and clasp
Alligator-grain leather, stitching density, and the tang or deployant finish are cheap to fix and easy to spot. A stiff, glossy strap usually means the rest of the watch was built to the same budget.
Realistic parameter bands
- Case diameter: 37 mm to 40 mm for a dress or chronograph Portofino build.
- Thickness: 9 mm to 11 mm for time-only, 12 mm to 13.5 mm for chronograph.
- Lug width: 18 mm to 20 mm, matched to the strap taper.
- Weight on leather: roughly 55 g to 80 g, depending on movement and caseback.
- Power reserve: 38 h to 42 h is normal for the common movements used.
- Water resistance claim: 30 m to 50 m on paper, splash resistance in practice.
- Crystal: sapphire with underside anti-reflective coating.
Pitfalls to avoid
- "1:1" and "super clone" language with no photos of the actual unit.
- Pre-order deposits from a seller with no transaction history.
- Listings that reuse genuine press images as "QC photos."
- Version numbers that jump without a documented change list.
- Skipping a reset and timegrapher video on any chronograph build.
- Assuming a replica carries brand service or warranty coverage. It does not.
- Ignoring local law. Import rules on counterfeit goods vary by country and a seizure is your loss.
FAQ
Is v6 better than v5?
Often, but not automatically. Ask the seller to name the specific changes in this batch and compare them against photos of the previous revision. If the answer is vague, the label is doing marketing work.
Can a replica be serviced?
Common movements can be serviced by an independent watchmaker who works on clones, though parts access varies. Expect to explain what the watch is, and expect no support from the original brand.
How do I check the movement from photos?
Look at subdial spacing, hand stack height, and rotor engraving. A quick video with the crown operated tells you more than any still image.
What should a QC check include?
Dial centering, index alignment, date font and position, hand clearance, bezel and caseback fit, crown action, strap hardware, and a timegrapher reading if the seller has one.
