A genuine IWC Aquatimer on reference IW329045, bought from an authorized dealer or from a pre-owned seller who puts authentication in writing, is the only version of this watch worth your money. Four criteria drive that call: the reference number engraved on the caseback matches the paperwork, the movement and case finishing match IWC's own published specification for the reference, the seller accepts returns in writing, and the asking price sits inside the range set by recently sold comparables instead of far below it.
Why counterfeit and "first copy" listings fail on this reference
The Aquatimer is a dive watch, which means it is judged on things a counterfeit cannot deliver: gasket sealing, crown and bezel action, and a movement that survives service. Copy listings also carry real risk. Counterfeit goods are subject to seizure at import, and the money you spend is gone with the goods.
- Pros: low asking price, immediate availability, no waitlist.
- Cons: no manufacturer warranty or service path, unverified water resistance, seizure risk at customs, no resale value, no legal recourse if the seller disappears.
Use case: none that I would recommend. If the budget only reaches a copy, a legitimate alternative is a lower-priced genuine dive watch from a brand that services what it sells.
Option 1: Authorized dealer
- Pros: guaranteed authenticity, full manufacturer warranty, factory service access, correct box and papers from day one.
- Cons: full retail price, possible waitlist, limited room to negotiate.
Use case: buy here if this is a keeper and you want the warranty to transfer with no questions asked.

Option 2: Pre-owned and gray-market dealers
- Pros: meaningful savings against retail, wider immediate selection, some sellers include a third-party service record.
- Cons: warranty terms vary, condition grading is subjective, factory service history may be missing.
Use case: the right channel if you confirm the original warranty card, get the serial and reference photographed in writing, and pay by a method that can be reversed.
Option 3: Auction and collector channels
- Pros: access to rare variants, transparent bidding history, independent condition reports on better lots.
- Cons: buyer's premium on top of the hammer price, sold as-is in many cases, shipping and duty to plan for.
Use case: best for a buyer who already knows the reference and can read a condition report without help.
Parameters to verify before money moves
- Pull the official specification for IW329045 from IWC's own site and write down the case diameter, movement, and water resistance rating. Compare every listing against that list, not against another listing.
- Ask for a clear photo of the caseback engraving and the serial. The reference must read IW329045.
- Request the warranty card and any service invoice, photographed together with the watch.
- Confirm the return window and authentication clause in writing before payment.
- Check the price against several sold comparables, not one asking price.
Pitfalls that cost buyers money
- Stock photos instead of photos of the actual watch.
- Messaging-app-only sellers with no return address.
- Grading language such as "AAA" or "first copy" applied to a watch presented as genuine.
- Prices far under every comparable listing.
- Pressure to pay by irreversible transfer.
Bottom line
Buy the real reference through a dealer or a pre-owned seller who will document provenance and accept returns. On a dive watch like the IW329045, the parts that matter most, sealing and the movement, are exactly the parts a copy cannot replicate.
