Short answer

A replica Da Vinci IW376024 is a copy of an IWC Da Vinci chronograph. Listings run $150 to $450. Most copies use an Asian 7750 or a Sellita SW500. No replica uses the IWC calibre 89360. Movement layout, case thickness, and dial print are the three points that separate a $400 copy from a $160 copy.

The reference

IWC has used the Da Vinci name since 1969. The IW3764xx block belongs to the Da Vinci Chronograph line introduced in 2007. That generation carried the in-house 89360 calibre. IWC's public reference pages do not show IW376024 among the models checked, so confirm the number with IWC before you pay a premium for it. Replica sellers list the number; the brand archive checked for this guide did not.

Movement options in copies

  • Asian 7750: 28,800 vph, 40 to 44 hours of reserve, counters at 12, 6 and 9.
  • Sellita SW500: Swiss base, same counter layout, adds about $150 to the price.
  • "Clone 89360": no such movement exists. Sellers who claim it are mislabeling a 7750.

The real 89360 puts elapsed hours and minutes in one counter at 12 o'clock. Most replicas split them into two subdials. That detail is the fastest tell at arm's length.

Case and dial checks

Ask for caliper photos: diameter, lug to lug, thickness, lug width. Copies run 0.5 mm to 1.5 mm thicker than the original in many listings. Weigh the watch. A steel copy on a bracelet lands 20 to 40 grams under the genuine piece.

Gold-tone cases use PVD or electroplating at 3 to 5 microns. Rub-through shows at the crown, lugs, and clasp within months of daily wear. Crystal should be sapphire with inner anti-reflective coating. Mineral glass scratches in weeks.

Price bands

  • $150 to $220: Asian 7750, mineral glass, stamped clasp, flat dial print.
  • $250 to $350: sapphire with AR coating, solid links, cleaner subdial spacing.
  • $400 and up: Sellita movement, closer case profile, better brushing.

US legal facts

Counterfeit watches are illegal to import and to sell. 19 U.S.C. § 1526 lets US Customs and Border Protection seize and destroy shipments. Personal-use orders can be seized with no refund and no notice to the buyer. Sellers who process card payments for counterfeit goods face trademark liability under the Lanham Act.

Ask before paying

  1. Movement maker and model number, in writing.
  2. Case diameter, thickness, and lug width in mm, with photos on calipers.
  3. Crystal material and coating.
  4. Return window and who pays return shipping.
  5. Water resistance test result. Assume none. Do not swim with any copy.

Unverified claims

Terms like "1:1" and "same factory" have no standard meaning. IWC does not publish service parts for the 89360 to third parties, so no copy can carry a genuine movement. Treat any listing that says otherwise as a red flag.
