Fake IW545177: the short answer
There is no single "fake IW545177." Several workshops copy that reference, and the results land in very different places. Some are $400 watches with a stamped dial and a hollow bracelet. Some are $1,200 builds that need a loupe and a caseback tool to separate from the real thing. Which tier you are holding matters far more than the word "fake" does.
So the useful question is not whether it is a copy. It clearly is. The useful question is which tier it sits in, and whether the asking price matches that tier.
Start with the genuine reference, not the copy
Before you judge any replica, find the manufacturer's spec sheet for IW545177 and write down four numbers: case diameter, case thickness, lug width, and movement type. Those four are where most copies come apart.
Diameter is usually close. Thickness is where they cheat. A movement swap adds or removes a millimeter or two, and a millimeter is visible the moment the watch sits on a wrist next to a real one. Lug width is the other quiet giveaway, because a 20mm strap on a 19mm lug is a detail nobody fixes at the budget end.
The three tiers you will see
- Budget. Mineral glass, printed dial markers that sit slightly raised or slightly crooked, a rotor that spins like a coin in a can. The case profile is a rough sketch.
- Mid. Sapphire crystal, decent dial printing, a movement that keeps time within a few seconds a day if you get a good one. Bracelet end links may not sit flush.
- Top. Correct thickness, correct crystal dome, engraved caseback, movement with the right beat rate and power reserve. The gap between this and genuine is measured in hand-finishing, not in shape.
Movement is where the money goes
Ask what is inside and ask for a photo of it. If the seller cannot or will not show you the movement, that tells you a lot. A modified Asian automatic and a clone of the original caliber look nothing alike under a loupe, and they do not feel alike when you wind them. A hand-wound movement should feel smooth through the whole wind, not gritty near the end.
Dial and hands: the tells that survive a photo
Look at printing under magnification. Genuine dial text is crisp with hard edges. Copies show bleed, uneven spacing, or a font that is a hair too bold. Check whether the markers line up with the minutes track. Check whether the hands are the right length, since short hands are a common cost cut. Date windows sit in the wrong spot more often than people expect, because the underlying movement dictates that position.
Photos lie in a specific way
Product shots are lit to flatter. Ask for a plain daylight photo of the watch on a table, plus a wrist shot, plus a shot of the caseback with the protective sticker off. If every image is a studio render or a copy of someone else's listing, stop there. Reverse image searching a listing photo takes ten seconds and saves a lot of money.
Price sanity check
Compare the asking price with what used genuine examples of that reference sell for. If the number is more than roughly a tenth of the real market value, you are paying top-tier money and you should be getting top-tier execution. Anything above that and you are being asked to fund someone's rent.
What I would ask before paying
- Which factory made it, and what tier is it?
- Case diameter and thickness, measured, not quoted from a spec sheet.
- A photo of the actual movement, not a stock image.
- What the return policy is if the watch arrives with a misaligned dial.
- Whether the crystal is sapphire and whether it has anti-reflective coating on one side or both.
