The short version: "V10" is a seller's batch label, not a quality grade. Before you pay for a fake IWC ref. IW329113 advertised as V10, ask for dated photos of the exact watch you will receive, find out which movement is inside, and compare the dial print, date font and caseback engraving against reference photos of the genuine piece. If the seller cannot produce those three things, the version number is decoration.
Fake IW329113 v9: What It Is and How to Check One
What the version label does and does not mean
Replica factories do not publish model years, spec sheets or part numbers. Sellers invent version tags, and those tags move upward as a marketing device. Two listings can both say V10 and ship very different watches, because the label describes a seller's claim about a batch, not a manufacturing standard. Treat the number as a starting point for questions, never as proof of anything. The useful question is not "which version is this" but "what changed since the last one, and can you show me."
What to verify before you pay
- Photos of the actual unit. Ask for front, caseback, crown side, clasp and a lume shot, all dated. Stock renders and reused photos from another listing are the single most common reason buyers end up with a lower tier watch.
- Movement disclosure. Credible builds in this tier use a Miyota 9015 or a clone of a Swiss automatic. Ask which one, then ask for a timegrapher reading: rate in seconds per day, amplitude, and beat error.
- Dial print and date font. Compare letter spacing, the thickness of the hour markers, and the shape of the numerals in the date window against genuine reference photos. Misaligned date wheels are the classic tell on this reference family.
- Caseback engraving. Replica engraving is usually shallow with rounded edges. Genuine engraving sits deeper with crisp walls. A sharp macro photo settles it.
- Bracelet and end links. Check for rattle, sharp inner edges, and whether the end links sit flush against the case with no light gap.
- Water resistance claims. Treat anything above splash resistance as unverified unless the seller shows a pressure test result for that specific watch.
Parameter bands to expect
- Case: 42 mm nominal diameter, roughly 13 to 14 mm thick, 150 to 170 g on a full bracelet.
- Movement: Miyota 9015 at 28,800 vph with about 42 hours of reserve, or a 2892 style clone with a similar reserve.
- Rate: plus or minus 15 seconds per day is normal for this tier. Past 30 seconds per day, reject it.
- Lume: should charge in about 30 seconds and fade over 4 to 6 hours. Patchy or dead lume is a common shortcut.
- Bezel, crown and pushers: firm detents, no wobble, no grit in the threads.
- Relative pricing: a quote well below the rest of the market for the same described build usually means a lower tier watch wearing a V10 label.
Pitfalls that cost real money
- Paying through irreversible methods with no dispute window. Use a channel that lets you open a claim.
- Sellers who answer spec questions with version numbers instead of measurements.
- Version inflation: V11 and V12 appear quickly, often with no change beyond the sticker.
- Ignoring the legal side. Trafficking in counterfeit goods is illegal in the US, shipments can be seized, and there is no warranty, no service network and no parts support behind the watch.
FAQ
Is a V10 better than a V9?
Only if the specific watch fixes something concrete: cleaner dial print, a corrected date font, tighter bracelet fit. Ask what changed. If the seller cannot name a change, pay the older price or walk away.

Can I judge the tier from photos?
Mostly yes. Ask for three crops: the dial at 12 o'clock, the date window, and the caseback. Rehaut depth and hand finishing also show up in a decent macro shot.
Does the movement choice matter that much?
It matters more than the version label. A regulated Miyota 9015 is serviceable and keeps reasonable time. An unknown clone may not accept standard parts, which makes future repair difficult.
How do I confirm water resistance?
You cannot confirm it from a listing. Assume splash resistance only, keep it out of pools and showers, and have any watch you intend to wear near water tested by a local watchmaker first.
