Answer first
IW938993 uses the IWC format of IW plus six digits, but no IWC catalog page matches that number. Confirm the source model before you pay. Then check five items: case size, dial layout, movement type, caseback engraving, and timegrapher numbers. Ask for caliper photos and a timegrapher video. Skip sellers who send only catalog photos.
Step 1: Confirm the reference
IWC catalog numbers run from the IW3xxxxx block to the IW7xxxxx block. A number in the IW9xxxxx range does not appear in dealer lists. Ask which IWC model the watch copies, the case diameter in mm, and the production year. A reply with no diameter is a red flag.
Step 2: Case and dial
Ask for a photo with calipers on the case. Get lug-to-lug and thickness in the same photo. Replica chronograph cases run 41mm to 44mm across and 13mm to 15mm thick. Check date window position, sub-dial spacing, and pusher finish. Crooked markers and an off-center date show a low-grade build.

Step 3: Movement
Most replica chronographs use an Asia 7750. It beats at 28,800 vph (4 Hz) and drives a 12-hour chronograph. Builds with running seconds at 6 o'clock add a transfer gear set, and that gear set is a wear point. Swiss ETA 7750 versions cost more. Ask for a timegrapher read: rate within plus or minus 10 s/day, amplitude 250 to 310 degrees, beat error under 0.5 ms.
Step 4: Caseback, crystal, and water resistance
Ask for a sharp photo of the caseback. Engraving depth and font matter. Sapphire should show no scratches and a clean edge at the bezel. Water resistance on replicas is not tested to ISO 22810. Treat the watch as splash-safe at most. Do not swim with it.
Step 5: Price, payment, and legal risk
Replica chronograph prices run from about $200 to $700. Swiss-movement builds sit at the top of that range. Payment by irreversible transfer removes your recourse. US Customs and Border Protection can seize counterfeit imports under 19 U.S.C. 1526. The shipment is lost and the refund is rare.
Checklist before payment
- Caliper photo of case diameter, thickness, and lug width
- Timegrapher photo or video
- Caseback and clasp photos in daylight
- Return window in writing
- Movement name on the invoice
If the seller cannot supply these five items, the listing is unverified. No photo set means no purchase.
