A fake IW323772 is a counterfeit copy of the IWC Aquatimer Automatic 2000, and it fails on three checks: the case back engraving, the titanium case and its weight, and the in-house caliber 80110 movement. Genuine watches carry crisp, deep engraving with matching reference and serial numbers, a lightweight grade 5 titanium case, and an IWC-signed movement that replicas do not reproduce accurately. If any one of those checks fails, treat the watch as fake.
What is the IW323772 reference?
IW323772 belongs to the IWC Aquatimer Automatic 2000 family, reference IW3237, a 44 mm dive watch introduced in 2009 with an internal rotating bezel and a titanium case. IWC adds a two-digit suffix to each variant, so the full designation pins down one specific case, dial, and strap combination. Counterfeiters copy the visible parts of that combination and rarely match what sits underneath.
How can you tell a fake IW323772 from a genuine one?
Case back engraving and serial numbers
Genuine IWC case backs are engraved rather than printed, and the lettering sits at an even depth with sharp edges. Look for the reference together with a serial number, and check that both appear on any paperwork. Replicas often use shallow etching, wrong fonts, or a serial that does not match the reference family.
Case material and weight
The Aquatimer Automatic 2000 uses grade 5 titanium, which is lighter and greyer than stainless steel and reads warm under light instead of mirror bright. A counterfeit built from steel feels heavy for its size and polishes up brighter than the original. Ask the seller for the weight in grams before you commit.
Dial, bezel, and hands
The internal rotating bezel is driven by a separate crown and should click firmly with no wobble; on fakes the gearing is loose or the bezel drifts on its own. Check the lume under UV: genuine IWC lume is applied with clean edges and glows one consistent color across indices and hands. Replicas show patchy lume, misaligned markers, or a flat printed dial texture.
Movement and winding
The genuine watch runs IWC caliber 80110 with Pellaton winding, visible through the sapphire case back with proper striping and engraved markings. Counterfeits use a generic Swiss or Asian automatic with a decorated rotor that hides the finish. A watchmaker can open the case and settle the question in minutes.
How common are fake IW323772 watches?
Counterfeit watches are a large global market, and IWC is copied less than Rolex but still targeted, with the sportier Aquatimer and Pilot lines most affected. That relative rarity is the trap: buyers who know Rolex fakes well assume an IWC copy must be genuine. Listings sold as Swiss super clones appear on marketplaces and social channels at prices far under the real market.
What is a genuine IW323772 worth?
Pre-owned Aquatimer Automatic 2000 references trade in the low four figures in US dollars, depending on condition, box, and papers. A seller asking a few hundred dollars for a new one is selling a replica, not a bargain. Check current listings on a trusted pre-owned platform before you negotiate.
What should you do if you suspect a fake?
- Stop the payment and ask for a sharp photo of the case back with the serial readable.
- Request authentication or a service estimate from an IWC authorized service center.
- Ask whether the seller can supply an IWC Extract from the Archives or original purchase paperwork.
- Walk away if the seller refuses an independent inspection or takes untraceable payment only.
Is a 1:1 super clone IW323772 ever worth buying?
No. A replica has no service history, uses a movement no watchmaker will warranty, and cannot be resold as a collectible. The visible details may pass at arm's length, but the case back, movement, and paperwork will not survive inspection. Buy a genuine pre-owned IWC or a well-regarded alternative instead.
