Quick answer
A replica IW329093 is a copy of the IWC Aquatimer Automatic 42 mm. Copies sell for about $120 to $550, with the useful tiers starting near $250. The case is steel, 42 mm wide, about 14 mm thick, with a sapphire crystal and an inner dive scale driven by the outer bezel. Movement choices run from a Miyota 9015 to a clone of the Sellita SW300. Water resistance on a replica is a seller claim, not a tested rating.
What the IW329093 is
The IW329093 sits in the IWC Aquatimer line. Steel case, 42 mm diameter, about 14 mm thick. Dive scale under the crystal, linked to the outer bezel. Crown at 3 o'clock, date at 3. Bracelet or strap depends on the variant. Reference numbers in this family differ by small details such as dial color and strap type, so confirm the exact build on IWC's own product page before you compare copies.
Replica grades
- Low: $100 to $180. Alloy case or thin steel, mineral glass, quartz or a basic automatic, printed dial text.
- Mid: $200 to $320. 316L steel, sapphire with inner anti-reflective coating, Miyota 9015 or Seagull ST2130, applied markers.
- High: $350 to $550. Clone SW300 or a tuned 9015, case thickness close to the original, clean bezel action, dial finish close to the real part.
Movement choices
Ask the seller which movement ships in the unit. The Miyota 9015 runs at 28,800 vph, 24 jewels, about 42 hours of power reserve. The Seagull ST2130 runs at 28,800 vph and costs less. Clone SW300 movements copy the Sellita SW300-1 layout, which keeps the case thin and the hand stack in the right order. A 21,600 vph movement paired with a thick case points to a lower tier.
What to check before you pay
- Case thickness. Over 15 mm on this reference means a thick movement or a loose case.
- Bezel action. The inner scale should turn with the outer bezel and hold position without play.
- Crystal. Sapphire with coating on the inside face. Mineral glass scratches within months.
- Lume. Two-tone lume on the markers and the bezel pip. Weak glow is common on low tiers.
- Water resistance. Treat it as unproven. Do not swim with the watch until a local watchmaker pressure tests it.
- Photos of the actual unit, not catalog renders.
- Return terms in writing, plus the movement name on the invoice.
Limits
Replica bracelets use stamped clasps and 316L steel with softer edges than the original. Caseback engraving and serial text often differ from the real reference. Resale value is close to zero. IWC service centers will not work on the watch, so any repair goes to an independent watchmaker. Buy a replica as a look, not as a dive tool.
