Short answer
The IWC Da Vinci IW3760 is a Swiss chronograph that IWC Schaffhausen sold from about 2007 to 2010. No replica of it uses the IWC movement inside the real watch. Copies sold under this reference run on third-party Chinese movements, cost from about $80 to $400, and carry no warranty from IWC. Trafficking in counterfeit watches is a federal crime in the United States under 18 U.S.C. 2320. US Customs can seize the parcel and the buyer loses both the watch and the money.
What the real IW3760 is
The IW3760 family covers the Da Vinci Chronograph line that IWC launched in 2007. IWC listed the watch in stainless steel, gold, and platinum, with several dial colors. Published specs for the family list a case in the 43 mm range, sapphire glass on the front and back, and a leather strap. The movement is the IWC calibre 89360, the first chronograph movement designed and built in house at Schaffhausen. Sources differ on exact case dimensions between references inside the family. Confirm the numbers for one reference against an IWC catalogue page or an IWC boutique before you trust any listing.
What replica listings claim
Replica listings for this reference reuse the same photos across dozens of sites. Common claims:
- 1:1 or super clone case and dial.
- Swiss movement. Most copies of this model use a Chinese automatic chronograph movement, often a Seagull or a copy of an ETA 7750 layout.
- Sapphire glass. Some units ship with mineral glass.
- Water resistance to 50 m or more. Copies are not pressure tested.
- Serial numbers that match a real watch. A copied serial does not make a watch genuine.
Price bands
Buyer forums report three bands for these copies: $80 to $150, $200 to $300, and $400 and above. Higher price does not track with a real movement. Genuine IW3760 watches on the secondary market sell for several thousand US dollars. That gap is the main signal in any listing.
Physical checks
- Subdial layout. IWC built the 89360 with a combined hour and minute counter. Copies that use a 7750 base show a 30-minute counter instead.
- Caseback engraving. Compare letter spacing and depth against an IWC photo. Engraving on copies is shallow or filled.
- Weight. A steel IW3760 case is heavier than most copies.
- Service. IWC service centers do not service counterfeit watches.
Verify each point against IWC photos of the exact reference. Photos of one reference do not describe another.
US law
18 U.S.C. 2320 makes it a crime to traffic in goods that bear a counterfeit mark. A first offense by an individual carries up to 10 years in prison and a $2 million fine. The Lanham Act lets a brand owner sue for damages and attorney fees. US Customs and Border Protection seizes counterfeit shipments and notifies the rights holder.
What a copy does not give you
No manufacturer warranty. No parts from IWC. No service. No resale market. No valid appraisal. Insurance claims rest on a genuine serial and paperwork.
Questions to ask in writing
- Which movement, by maker and calibre number?
- Who pressure tested the case, and at what rating?
- Where does the seller ship from, and who handles customs?
- What is the return window, in days?
If a seller will not answer in writing, the listing has no verifiable facts.
