The short answer
The IW376006 is a Da Vinci Chronograph from the ref. 3760 family, and one feature decides whether a replica is worth owning: the dial. The real watch has two subdials, one at 12 and one at 6, and the top register counts elapsed hours and minutes together. Get that right, pair it with a sapphire display back and a 43mm steel case, and you have one of the better IWC fakes on the market. Get it wrong and you are wearing a generic chronograph with an IWC logo glued on.
What the genuine watch actually is
IWC introduced the Da Vinci Chronograph in 2007, and it was the debut of the calibre 89360, the company's first in-house chronograph movement. The movement is the reason the dial looks the way it does, so it is worth knowing before you compare anything.
- Stainless steel case, roughly 43mm across and fairly tall on the wrist
- Black dial with a date window at 3
- Combined hour and minute counter at 12, small running seconds at 6
- Flyback chronograph, meaning one push resets and restarts the timer
- Sapphire crystal front and a sapphire display back
- Alligator strap on a steel folding clasp
The dial is where replicas fall apart
I look at the subdials before anything else. On the genuine 89360, the 12 o'clock register holds two hands in a single circle, a short one for elapsed hours and a longer one for minutes. That is the signature of this reference, and it is also the hardest thing to fake.
Most replica chronographs start life as a Valjoux 7750 style movement, which normally drives three registers at 12, 6 and 9. Makers work around this in two ways: they blank the third register so the dial looks bicompax, or they leave all three and hope nobody notices. Both are wrong. If you see a stub of a subdial at 9, or a single-hand counter at 12, the watch is not a faithful copy of this reference.
Then check the small details. The date aperture should sit at 3 with a clean cut, not a printed window on the dial. Subdial rings should be recessed, not stickers. Hands should be the right length, reaching close to the minute track without overrunning it.
Case, crystal and case back
The real watch has a sapphire display back, so the movement is visible. A replica with a solid steel back is hiding something, and it is usually a movement that would embarrass the seller. Through a display back I want to see reasonable finishing on the bridges and a rotor marked with IWC's Probus Scafusia motto.
On the outside, look at the crystal first. Sapphire with anti-reflective coating disappears at angles. Cheap mineral glass glows purple or blue and shows reflections from across the room. The crown and pushers should screw down or seat firmly without wobble, and the lugs should curve with the case rather than sit as separate blocks.
Strap, clasp and weight
A replica is often let down by the strap. Genuine alligator has irregular scale patterns and soft edges. Embossed leather looks stamped and repeats the same scale shape. The folding clasp should close with a solid click and the engraving should be crisp, not shallow and smeared.
What no replica gives you
It is worth saying plainly: a replica is not a Da Vinci. IWC will not service it, the movement is not the 89360, and the resale value is close to zero. Counterfeit imports can also be seized by US Customs, which means your money can vanish with the parcel. Treat the purchase as a costume piece you enjoy wearing, not an asset or a substitute for the real thing.
Quick checklist
- Two subdials only, at 12 and 6. No third register at 9.
- Two hands in the top register, hours and minutes.
- Date at 3, cut into the dial.
- Sapphire front and back, not mineral glass.
- 43mm steel case with articulated lugs.
- Push buttons that click and reset cleanly.
