Short answer
The replica IW329104 is a copy of an IWC Aquatimer Automatic 42, a 42 mm stainless steel dive watch rated to 300 m with an automatic movement and a rotating dive bezel. Replicas exist at several price and quality tiers. None matches the original in movement, materials, or water resistance, and counterfeits are illegal to import or sell in the United States. A buyer who wants the look of this reference should compare case dimensions, bezel action, dial printing, and movement type before spending money.
Prerequisites
- A caliper or steel ruler for measuring the case
- Catalog photos of the genuine reference for side by side comparison
- Basic knowledge of automatic movements and dive bezel systems
How to check a replica IW329104
- Confirm the reference number against IWC's official catalog, because the Aquatimer line uses a new reference for each generation.
- Measure the case across the widest point with the crown excluded, and compare the reading to the 42 mm case of the genuine watch.
- Inspect the bezel, which on the original links the outer ring to an inner scale, while many copies use a plain friction ring.
- Ask which movement sits inside, since the authentic watch uses an IWC automatic and copies use generic third-party calibres.
- Compare dial text with a catalog photo, checking the font, the spacing, and the position of the brand name.
- Check the date window alignment and the lume application under low light.
- Weigh the watch, because case and bracelet mass differs between steel and plated base metal.
- Study the engraving between the lugs and on the caseback, which many copies leave shallow or off center.
- Treat every water resistance claim as unverified and keep the watch out of water.
Where replicas fall short
Case finishing on a copy rarely matches the crisp transitions of the original. Crystal coating, crown threading, and gasket quality also differ, which is why a replica should not be worn for diving or swimming. Servicing is another problem. Many replica movements cannot be repaired with original parts, and independent watchmakers may refuse the work. Resale value sits near zero, so the money spent is gone.
Legal considerations
Counterfeit watches infringe trademarks. U.S. Customs and Border Protection can detain, seize, and destroy shipments of counterfeit goods, and trafficking in counterfeits carries civil and criminal penalties. A traveler who carries a counterfeit watch may have it confiscated at the border. Anyone who wants the Aquatimer look without legal risk has other options, including a pre-owned genuine model or a dive watch from a brand outside the protected design.
