Short answer
A fake Da Vinci IW3760 is a counterfeit copy of an IWC watch from the Da Vinci line. Sellers price these replicas at $90 to $400. A used genuine Da Vinci Chronograph from the same period sells at $5,000 to $11,000. Replica makers do not build the IWC 89360 chronograph movement. They fit Asian or Swiss ETA clones inside a copied case. That gap is the main test.
What the IW3760 is
IWC launched the Da Vinci name in 1969. The 2007 to 2011 generation used barrel-shaped, or tonneau, cases. Reference numbers in that group start with IW3760 and IW3764. Chronograph versions carried the in-house calibre 89360. That movement is automatic, it has a flyback function, and it puts elapsed hours and minutes in one counter at 12 o'clock. Most spec sheets list a 43 mm case and 30 m water resistance.
IWC retired the tonneau shape in 2017 and moved the Da Vinci line to round cases. A "new" IW3760 in a round case is a wrong case. The reference does not exist in that shape.
Reference suffixes
A full IWC reference has ten characters, for example IW376401. The last two digits mark case metal, dial, and strap. Listings often shorten the number to IW3760. Ask the seller for the full reference stamped on the caseback.
Price check
- Replica listings: $90 to $400
- Genuine used, steel, no box or papers: $4,500 to $8,000
- Genuine used, full set, serviced: $8,000 to $12,000
Prices move with metal, dial color, and service history. Check completed sales on a used-market platform before you bid. A seller who offers a "new old stock" IW3760 at $500 is selling a replica.
Photo checks
- Caseback engraving. Genuine IWC engraving is crisp with sharp edges. Replica engraving looks shallow and rounded.
- Dial printing. The "IWC" and "SCHAFFHAUSEN" lines sit level with even spacing. Crooked or thick text is a fake sign.
- Counter layout. The 89360 uses one combined counter at 12 o'clock. Many replicas copy a two-subdial layout from another watch.
- Hands. IWC finishes hands with sharp edges. Replica hands show burrs and rough tips.
- Crown. The crown sits flush with the case band and threads smooth.
- Screws. Look for scratched slots on caseback screws. Factory assembly leaves clean heads.
- Crystal. The sapphire has anti-reflective coating on the inside. A blue glare that washes out the dial points to a coated fake.
- Weight and size. Ask for a photo on a scale. Compare diameter, thickness, and lug width with the spec sheet.
Movement checks
Ask for a video of the chronograph in motion. Press start, run 60 seconds, press stop, then reset. A flyback movement restarts a running chronograph with one press of the reset pusher. Clones without flyback stop and reset in two steps. A watchmaker can open the caseback and name the calibre in minutes.
Paperwork, serials, and service
IWC stamps a serial number on the caseback and ties it to service records. Counterfeit sellers reuse the same serial across many watches. Search the number and see if it appears in more than one listing. Box, warranty card, and booklet are easy to copy. Papers from an IWC service center are harder to fake. IWC service centers can open the watch and confirm the movement.
Where fakes appear
Replica IW3760 listings appear on social media marketplaces, classified sites, and auction pages that allow no returns. Sellers use phrases such as "1:1 Swiss," "clone," "super clone," and "high version." Customs agencies seize counterfeit watches at US ports. Import of a counterfeit watch violates 19 U.S.C. 2320, and the shipment can be destroyed.
What photos cannot show
Photos hide movement finish, caseback thread quality, and gasket condition. Water resistance on a replica is not tested. A fake rated at 30 m may leak on the first swim. IWC service pricing varies by center and by the work needed. Ask for a quote before you buy.
Before you buy
- Get the full reference from the caseback.
- Get the serial number and search it.
- Ask for a movement video with the chronograph running.
- Meet at a watchmaker for a caseback inspection.
- Pay with a method that allows a chargeback. Wire transfer and crypto do not.
