Quick answer
The replica IWC Da Vinci IW376045 copies a Da Vinci Automatic from IWC's IW3764 family. Listings state a 41 mm steel case, a sapphire crystal, a leather strap, and an Asian automatic movement with a date window and small seconds. Price runs from about $80 to $400. Build quality tracks price. Ask for photos of the caseback, the crown side, and the rotor before you pay.
What the reference is
The Da Vinci line sits in IWC's catalog as a dress watch family. The IW3764 group uses a cushion shaped case with rounded lugs, a stepped bezel, and a dial with applied markers. Replica factories work from photos and from hands-on scans of genuine watches. Accuracy varies by batch, not by seller name.
Case and crystal
- Case: polished steel, about 41 mm wide, 12 mm thick on most listings. Confirm with a caliper photo.
- Crystal: sapphire on the better builds, mineral glass on cheap ones. A sapphire top has a sharp edge and no visible scratches after a wipe.
- Caseback: solid steel with engraved text. Look for straight lettering and even depth. Shallow laser etching is a sign of a low tier build.
- Crown: signed, with clean knurling. A crown that sits off center points to a mismatched case.
Dial and hands
Check four points. First, marker alignment at 12. Second, the date font and the position of the window. Third, hand length: the minute hand should reach the minute track. Fourth, print quality on the logo. Poor copies use flat white paint with fuzzy edges.
Movement
Most replicas run an Asian automatic such as a 2824 clone or a Miyota based unit. Cheap versions run quartz, and the second hand jumps instead of sweeping. Sellers do not always name the movement. Ask for a video of the seconds hand and a photo of the rotor engraving. Note: the exact caliber inside a given replica is not public information, so treat seller claims as unverified until you see the movement.
Strap, clasp, and water resistance
Stock straps are leather with a steel pin buckle. Check stitch density and the tang finish. Do not trust water resistance claims on a replica. Gaskets on low tier builds are thin. Keep the watch away from water.

Legal note
A replica carries the IWC trademark without authorization. Sale and import of counterfeit goods is illegal in the US and the EU. Customs seizures happen. Buy with that risk in mind.
