Short answer
A replica IW329061 is a copy of an IWC Aquatimer Automatic in the 42 mm case family. Online sellers price these between about $150 and $600. The genuine watch carries a 300 m water resistance rating. Copies do not. Ask for a pressure test result, or keep the watch out of water.
What the reference number covers
IWC reference numbers run six digits after the IW prefix. The 3290 block is the Aquatimer Automatic 42. The final digits set dial color, strap or bracelet, and market. IWC's own catalog is the source of record for a suffix. Confirm the exact number there before you buy. Resale listings copy each other, and numbers drift between pages.
Specs to compare side by side
- Case: steel, 42 mm diameter, roughly 14 mm thick
- Bezel: internal dive scale with a one-way action and IWC's SafeDive system
- Crystal: sapphire, flat with slight doming
- Water resistance: 300 m on the genuine watch
- Dial: applied markers, lume on hour markers and hands
- Bracelet or strap: steel links or rubber, depending on the suffix
Where replicas fall short
Case size is the first check. Many copies measure 0.3 to 0.5 mm off, and the error shows at the lugs. Bezel action is the second check. A correct internal bezel clicks in one direction with no play. A weak copy turns both ways or feels loose. Lume is the third check. Factory lume glows for hours. Copy lume fades in under an hour. Bracelet end links and clasp engraving are the fourth check. Gaps at the end links are common.
Movements used in copies
Most replicas at $150 to $300 run a Miyota 9015 or a Seiko NH35. Watches at $350 to $600 may claim a Swiss ETA 2824 or a clone of it. Ask the seller to name the movement in writing. Ask for a timegrapher photo with rate, amplitude, and beat error. A rate inside plus or minus 15 seconds per day is a fair result for this price band.
Checks before you pay
- Request photos of the case back, crown, and clasp under daylight.
- Ask for the movement name and the timegrapher reading.
- Ask if the watch passed a pressure test. Skip the swim if the answer is no.
- Confirm the return window and the payment method in writing.
- Compare the dial layout to photos on IWC's site, not to other seller listings.
Legal note for US buyers
US law treats goods that carry a registered trademark without authorization as counterfeit. Customs can seize shipments. Sellers can face civil penalties. Buy with that risk in mind.
