Before you spend money on an IW323747 that does not come from the original maker, decide what you are actually buying: a watch that copies the look, not the watch. Compare every listing against the official specifications for the reference, ask for caliper and movement photos, and treat any claim that cannot be photographed as unproven. If the seller cannot show the caseback engraving, the movement, and the bracelet end links in one set of photos, walk away.

What buyers mean by "fake IW323747"

Two different things get that label. The first is a counterfeit that pretends to be the genuine article, often sold with copied packaging and papers. The second is an openly sold replica or homage that borrows the case and dial design without claiming to be original. The checks below apply to both, because the weak points are the same: case finishing, dial printing, bracelet fit, and the movement behind the caseback.

What to inspect before you pay

Case and crystal

• Ask for caliper photos across the case at the widest point, at the bezel, and at the caseback. Compare those numbers to the dimensions the original maker publishes. A listing that quotes one diameter and shows another is a red flag.
• Look at the lug profile and crown guards. On copied cases the lug edges are often softened and the crown sits slightly proud or recessed.
• Check the case flanks for brushing that runs in one direction only. Mixed polish and brush lines with fuzzy transitions show up under a phone flash.
• Sapphire should show a faint blue or purple reflection at an angle. Plastic or mineral crystals reflect and scratch differently.

Dial and hands

• Print quality decides most of the look. Compare the thickness of the brand text, the applied markers, and the spacing of the minute track against official photos.
• On date models, the frame around the date window and the font of the numerals are common tells. The frame should sit square to the dial, not tilted.
• Applied indices should sit flat and level. Ask for a straight-on dial photo rather than a three-quarter shot that hides alignment.
• Lume plots with uneven edges and a chalky surface show up fast under a loupe.

Bracelet and clasp

Integrated bracelets are where copies show fastest. Ask for photos of the end links seated against the case. A visible gap, or end links that rock when pressed, means the case and bracelet were not machined as a set. Check that the clasp engraving matches the wording on the caseback and that the folding parts lock with one clean click instead of two soft ones.

Movement and caseback

• Request a photo of the movement with the caseback removed, or a short video of the rotor turning.
• Reference-grade automatics typically beat at 28,800 vibrations per hour, or 4 Hz. A slower sweep, or a stutter when the seconds hand moves, points to a cheaper movement.
• Caseback engraving should be crisp with consistent depth across letters and numbers. Etching that fades at the edges is a factory tell.
• Confirm that the reference number, case number, and any water resistance marking agree with each other and with the listing.

Parameter bands to compare

Use these as a checklist rather than a spec sheet. Every number should come from a photo or a measurement, not from the listing text.

• Case diameter: match the maker's published figure within about 0.5 mm when measured without the crown.
• Case thickness: copied cases often run 1 to 2 mm thicker to fit a generic movement and spacer ring.
• Lug width and end link fit: the bracelet should meet the case with no step and no gap.
• Weight: a steel case and bracelet at the same dimensions should land within a few grams of a known-good example.
• Beat rate: 28,800 vph is the expected figure for this class of movement.
• Water resistance: treat any rating above 100 m as unverified unless the watch has been pressure tested.

Pitfalls that cost real money

• Buying from a listing that shows stock photos only. Stock images prove nothing about the unit you will receive.
• Paying a premium for "Swiss made" claims without movement photos. The marking alone carries no weight.
• Ignoring the service question. Replica movements are often assembled with thin lubrication, so a cleaning and re-lube can eat a large share of the purchase price.
• Assuming box and papers mean anything. Packaging is copied as easily as dials and adds no guarantee of quality.
• Skipping the legal check. Counterfeit watches infringe trademarks, and customs authorities in the United States and the European Union seize them, which means your money can disappear with the parcel.
• Paying by bank transfer or gift card. Use a method that has a dispute process.

FAQ

Can you tell a fake IW323747 from a genuine one on the wrist?

From across a room, usually not. At conversation distance, the finishing of the case flanks, the clarity of the crystal, and the way the bracelet meets the case are the first things that give a copy away.

Do replica movements last?

Some do, many do not. Expect a shorter service interval than a genuine movement, and budget for a watchmaker who is willing to work on it.

Where should I buy?

If you buy at all, choose a seller who publishes measurements, movement photos, and a return window, and who answers specific questions in writing. A specialist who handles this reference group regularly is a safer bet than an anonymous marketplace listing.

Is the resale value any good?

No. Replicas and counterfeits are not collectible and they lose value the moment they leave the seller. Buy only if you accept that.
