Most searches for "fake ingeniev4" are really about one thing: a fourth-generation counterfeit of the IWC Ingenieur, the Genta-designed steel sports watch with the integrated bracelet. The "v4" is not an IWC code. It is seller shorthand for the fourth batch a replica factory has released, and it tells you almost nothing about quality on its own. A v4 from one workshop can be worse than a v2 from another.
Where the version numbers come from
Replica factories iterate the same way any small manufacturer does. They build a run, buyers complain about the bezel screws or the dial texture, and the next run gets tweaked. Sellers then label the new batch v2, v3, v4 to signal that something changed. The number is marketing as much as engineering. Nothing about it is standardized across sellers, and two listings can both say v4 while shipping visibly different watches.
On the Ingenieur specifically, the version talk usually centers on the older ref. 1832 and 3521 pieces with the slotted bezel and the bracelet that flows straight into the case. That design is hard to fake well because the case and bracelet have to read as one continuous piece. Get the transition wrong and the watch looks clunky from across a table.
What actually changes between versions
From what I have seen in photos and comparisons, the meaningful revisions tend to land in a few spots:

- Bezel screws: count, slot depth, and whether they sit flush or proud of the surface.
- Dial finish: the grid or textured pattern, how crisp the lines are, and whether the printing sits flat.
- Case thickness and lug angle, which decide whether the bracelet drapes or sticks out.
- Bracelet taper and the fit of the end links against the case.
- Movement: decorated automatic vs. a plain workhorse, and how the rotor sounds.
- Crystal and AR coating, which affect how the dial reads under light.
A v4 label usually implies fixes to at least two of those. It rarely means all six were solved.
How I would check one in hand
- Look at the bracelet-to-case join from the side. A gap or a step is the fastest tell.
- Turn the bezel screws under a loupe. Shallow slots and uneven spacing show up fast.
- Check the dial print with a macro shot, not the naked eye. Rough edges show at 5x.
- Wind it and listen. A gritty rotor or a loud tick does not match the original.
- Weigh it. Thin cases and hollow links come in light.
- Ask for the movement name. Sellers who cannot name it usually do not know what is inside.
The parts the version number ignores
Legality is the big one. Importing counterfeit goods into the US is prohibited, and Customs can seize a shipment with no refund to the buyer. Reselling a replica as genuine is a separate and more serious problem. Service is the second issue. Independent watchmakers often decline to work on counterfeits, and parts do not exist for them, so a broken movement can mean a dead watch. Resale value is effectively zero, which is fine if you treat the purchase as a novelty and not an asset.
My honest take: the version number is a starting point for questions, not a quality grade. Ask what changed, ask for macro photos, and assume the answer is optimistic until the pictures say otherwise.
