The short answer
IW323752 is an IWC Schaffhausen reference number, and it belongs to the Aquatimer family, the brand's dive watch line. A replica IW323752 is a copy of that watch. It is not made by IWC, it does not contain IWC movement parts, and nobody at the brand will service it. Sellers know that, and many listings dance around it, so the honest starting point is simple: you are buying a look, not the watch.
What the real reference is
The Aquatimer block that includes 3237 covers a stainless steel dive watch in the low 40mm range, with a rotating dive bezel, an automatic movement, and either a rubber strap or a steel bracelet depending on the variant. IWC's own product pages are the only reliable place to confirm the exact case size, dial color, and movement for a specific number, because the same case block often spans several versions with different finishes and straps.
That matters for replica shopping. If you compare a copy to the wrong original photo, you will judge it against specs it was never built to match.
Where copies of this model usually land
- Case and dial: the better tiers get the silhouette, the bezel profile, and the dial layout close. This is the part sellers photograph most.
- Movement: the biggest gap. Expect a generic Japanese or Chinese automatic, sometimes quartz on the cheap end, never the in-house calibre. Winding feel, accuracy, and serviceability all change with that.
- Bezel action: dive bezels are finicky to reproduce. Copies often feel gritty or lose their click after a few months.
- Crystal and lume: mineral glass instead of sapphire on lower tiers, and lume that fades within an hour or two.
- Water resistance: treat every depth rating as marketing. A copy advertised at 200m has not been pressure tested to 200m.
What to check before you pay
- Photos of the actual unit, not factory renders or borrowed images.
- The movement name, and whether a local watchmaker will open it at all.
- Case diameter and lug width, so straps and bracelets will actually fit.
- Return window, and who pays return shipping.
- A payment method you can dispute if nothing arrives.
- Whether the seller states plainly that this is a replica. Vague wording is a warning sign.
The legal and practical side in the US
Watches carrying a trademarked logo without authorization are illegal to import into the United States. Customs can seize and destroy a shipment, and buyers usually do not get that money back. On top of that, you get no warranty, no parts support, and resale value that sits near zero. If the watch arrives broken or stops after a month, the only remedy is whatever the seller's return policy says.
If you mainly want the look
Homage watches and microbrand divers copy the general style without the trademark, and they come with warranties, spare parts, and no legal exposure. Seiko, Orient, and Citizen all sell dependable dive watches in the same size bracket. A used genuine Aquatimer costs more upfront but holds value and can be serviced for decades. That is worth weighing against a copy that will be hard to repair and impossible to sell.
