A fake IW323737 is a replica of an IWC dive watch reference, and the ones worth owning are separated from the junk by three things: case finishing, the movement inside, and whether the dial printing survives a loupe. Everything else is secondary. If a seller can't tell you what movement is in the watch, stop there.
Know which tier you're shopping in
Replica watches aren't one product. They're a ladder, and price tells you roughly where on the ladder you're standing.
- Budget tier. Roughly $40 to $90. Stamped cases, mineral glass, a low-grade automatic or a quartz pretending to be automatic. The date wheel font is wrong, the bezel clicks once and feels like gravel.
- Mid tier. Roughly $150 to $350. Solid stainless case, sapphire crystal, clone of an ETA movement. Decent on the wrist at arm's length. Falls apart under a macro lens.
- High tier. Roughly $400 to $800. Proper case machining, correct dial proportions, clone movement with decent finishing, real lume. This is where the term "super clone" gets thrown around, often dishonestly.
Any seller claiming genuine Swiss movement at a mid-tier price is lying. The math doesn't work.
Case and bezel first
I look at the case before the dial on any replica, because case machining is expensive and corners get cut there first. Run a fingertip along the lugs. Sharp edges mean a cheap CNC pass with no hand finishing. Check the lug holes and the space between the lugs, since that's where brushing and polishing usually look sloppy.

The bezel is the second tell. Grip it, turn it, and listen. A good one moves in crisp increments with no play and lines up dead on the marker. A bad one wobbles, sits crooked, or spins freely because the click spring is missing or too thin.
Dial, hands, and printing
Use a loupe or a phone macro shot. On a clean replica the markers are applied, not painted, and they sit level. The text is crisp with no bleeding at the edges. Hands are polished on the bevels and the lume fill is even, not lumpy or overflowing onto the metal. If the date sits off-center in the window, walk away. That's a dial or movement alignment problem you can't fix cheaply.
The movement question
This is where most buyers get burned. Ask directly: what caliber is inside, and is it a clone or a genuine ETA? Sellers who dodge that question are hiding something. On the high end you'll see clones of the ETA 2892 family, which is broadly what the original reference runs on. On the low end you'll get a 2813 or a decorated quartz. A decorated quartz will sweep smoothly on some models and tick on others, so ask for a video of the second hand.
Also ask how the watch keeps time. Anything beyond about plus or minus fifteen seconds a day out of the box is a sign of a movement that hasn't been regulated.
Water resistance is not what the engraving says
A caseback that says 300 meters means nothing on a replica unless it's been pressure tested, and most haven't. Treat any fake dive watch as splash resistant. Don't swim in it, don't shower in it, and don't assume the crown gaskets are siliconed. If water resistance matters to you, that alone is a reason to buy a real dive watch from a brand that fits your budget.
A pre-purchase checklist
- Get a timestamped photo and a video of the actual watch, not stock images.
- Confirm the movement name and version in writing.
- Ask about the crystal: sapphire with proper anti-reflective coating, or mineral glass?
- Ask whether the bracelet is solid link or folded, and whether the clasp is machined.
- Check the case diameter and thickness against the manufacturer's own reference data so you know what you're comparing to.
- Pay with a method that gives you recourse. Bank transfer to a stranger gives you none.
Red flags worth respecting
Photos that are all from one angle. A price far below the tier norm. Pressure to pay outside the platform. A seller who gets defensive when you ask about the movement. And any listing that quietly implies the watch is genuine. Beyond the quality problem, counterfeit watch trafficking is illegal in most markets and customs agencies seize these shipments routinely, so you can lose the watch and the money in one go.
Buy the tier, not the story. A well-made fake at a fair price is a known quantity. A bargain from an unknown seller is a gamble dressed up as a deal.
