Short answer: no counterfeit batch sold as a fake IW329013 delivers the watch that reference number describes. Listings using words like 1:1, first copy or mirror quality describe a production run that changes month to month, arrives with no warranty, and cannot be serviced or repaired by IWC. If you want the Aquatimer look on your wrist, the honest paths are the genuine reference on the secondary market or a plainly labeled homage from a brand that does not pretend to be Schaffhausen. This guide will not walk you through picking a counterfeit batch. It will tell you what the IW329013 actually is, where copies fall apart, and how to avoid paying genuine money for a fake.
What the IW329013 actually is
The IW329013 sits inside the IWC Aquatimer Automatic family, the dive line IWC rebuilt around an internal rotating bezel rather than an external one. Per IWC's published specification for the Aquatimer Automatic, the reference uses a stainless steel case around 42 mm across, water resistance rated to 300 metres, sapphire crystal with anti reflective coating on both faces, and calibre 30120 with roughly 42 hours of power reserve. The bezel is adjusted through the crown, and IWC's SafeDive system lets the dive scale move in one direction only so a knock against your gear cannot shorten your elapsed time.
- Case: stainless steel, roughly 42 mm, around 14 mm thick
- Strap or bracelet width: about 22 mm at the lugs, with IWC's quick change fittings
- Crystal: sapphire, coated front and back
- Water resistance: 300 m, crown and caseback sealed
- Movement: calibre 30120, automatic, approximately 42 hours of reserve
- Dial furniture: applied indices, generous lume plots, date window depending on the variant
Dial colour, strap type and packaging differ between Aquatimer variants, so always check IWC's spec sheet for the exact reference you are comparing against rather than trusting a listing photo.
Where copies give themselves away
The internal bezel is the hardest part of this watch to copy. On a genuine Aquatimer the crown pulls to a detent and the inner ring turns with a firm, geared feel before locking back down. Copies often use a friction fit that spins loose, or a crown that disengages the moment you push it in. Look at the crown threads, the caseback engraving depth, the colour shift of the anti reflective coating under a lamp, and how crisp the printed depth rating is. A genuine 300 m seal needs gaskets, tested tolerances and a screw down crown. A counterfeit claiming the same rating has none of that verification behind it.
Checking a watch offered as genuine
- Match the caseback serial to the paperwork, and confirm the reference number is correct for the dial and bezel configuration.
- Ask for photos of the movement through a display caseback, or take the watch to an independent watchmaker for a regulated rate check.
- Test the bezel action and crown detents by hand, not from a video.
- Buy only from a seller who accepts returns and provides service history.
- Budget for a full service on any pre owned Aquatimer, and treat that cost as part of the purchase.
Pitfalls to avoid
- Trusting the words 1:1 or Swiss made on a listing that names no factory and shows no service record
- Assuming a box and card set proves origin, since packaging is copied as readily as the watch
- Paying by methods with no chargeback route
- Believing a 300 m rating on a watch that has never been pressure tested
- Overlooking import rules, since counterfeit goods are seizable at the border in the United States and many other markets
FAQ
Is any fake IW329013 worth the money?
Not if you want the watch the reference number describes. The internal bezel, the crown feel, the movement and the water resistance are the substance of this model, and those are the parts copies cannot reproduce.
Can a counterfeit be serviced?
Independent watchmakers may work on generic movements inside a copy, but parts for replica cases, bezels and crowns are not supplied, so a broken internal bezel often ends the watch.
What is the closest legal alternative?
A genuine pre owned Aquatimer Automatic, or a clearly branded dive watch with a comparable case size, an internal bezel and a documented water resistance rating.
How do I protect myself when buying used?
Insist on a return window, an independent inspection, and photos that show the caseback serial and reference engraving in focus.
