Quick answer
The IWC Da Vinci Chronograph ref. IW376001 is a 43 mm steel watch on a leather strap. It runs calibre 89360, an in-house automatic chronograph. Replica copies sell for about $280 to $650. The good ones match the case width, the dial print, and the caseback engraving. No copy carries a calibre 89360. Most replicas use an Asian Valjoux 7750 clone with a decorated rotor plate.

Dial color and date layout differ across the 3760 references. Compare photos of a documented IW376001 before you judge any copy.
What copies get right
Top-tier copies match the 43 mm case width and the slab-sided profile. Dial text, subdial positions, and the crown at 3 line up with the original. Many ship with a sapphire caseback so the engraved rotor plate is visible.
What copies get wrong
Pusher feel is the first tell. Genuine pushers give a short, firm travel. Clones feel soft, and reset can stick. Date font and window shape are the second tell. Dial finish is a third: the original has a fine sunray or grained surface, while cheaper copies show a flat, printed look. Caseback engraving on copies is shallow and often misaligned with the reference number.
Inspection checklist
- Measure the case across the bezel. It should read 43 mm, without crown guards.
- Run the chronograph. The central hand should snap to zero on reset, not drift.
- Time the counter at 12. On the 89360 it tracks 12 hours, so after 35 minutes the hand sits near the one-third point. On many copies that register is a 30-minute counter.
- Check the date aperture if the reference has one. Compare the numeral font to a photo.
- Turn the watch over. Look at rotor engraving, jewel count, and screw heads.
- Check the strap. Factory straps are alligator with a signed buckle. Copies ship with embossed calf.
Price tiers
Genuine IW376001 examples trade on the secondary market near $4,500 to $8,000, based on box, papers, and service history. Replica tiers: $150 to $250 for basic builds, $300 to $450 for 7750 clone movements with a decent dial, $500 to $700 for the best dial work and decoration.
Limits
No replica of this reference carries an IWC movement, so service from IWC is not available and resale value is close to zero. Water resistance on copies is untested. Do not swim with one.
