The replica Da Vinci IW376018 is a copy of IWC's tonneau-cased chronograph, and the honest answer is that no replica reproduces its in-house calibre 89360. Buyers get one of three things: a quartz lookalike, an Asian 7750-based automatic with altered subdial functions, or a top-tier copy that matches the outside case but not the movement. Expect to pay roughly $90 to $700 depending on tier, and treat any claim of a true 1:1 movement as false.
What is the IWC Da Vinci IW376018?
The IW376018 belongs to the Da Vinci Chronograph family that IWC launched in the late 2000s. It uses a barrel-shaped steel case around 43 mm wide, a curved sapphire crystal, and the manufacture calibre 89360 with flyback and a combined hour and minute counter at 12 o'clock.
That combined totalizer is the model's signature. It is also the single feature most replicas get wrong, because the layout requires a movement built for it.
Why the movement is the hardest part to copy
The calibre 89360 stacks elapsed hours and minutes into one subdial. Most replica chronographs run a stock Asian 7750, which drives a 30-minute counter and a separate running-seconds dial.
On many copies the subdial at 12 tracks only 30 minutes, the subdial at 6 becomes running seconds, and the pusher feel is spongy. A seller who shows you a working flyback on video is showing you a genuine watch far more often than a replica.
What are the replica quality tiers for the Da Vinci IW376018?
Budget tier
Quartz or basic automatic movements, mineral glass, printed rather than applied markers, and a case profile that looks flat from the side. Prices sit near $90 to $160.
Mid tier
Asian 7750 automatic, sapphire crystal, applied indices, and a case that reads close to 43 mm. Bracelet and strap quality improves noticeably. Prices run about $200 to $400.
Top tier
Custom-bridged movements styled after the 89360, sharper case finishing, correct hand shapes, and anti-reflective coating on both crystal faces. Prices land between $450 and $700 or more.
How much should a replica Da Vinci IW376018 cost?
- Quartz lookalike: $90 to $160
- Automatic 7750-based: $200 to $400
- High-end automatic with decorated bridges: $450 to $700
Anything priced under $70 is a fashion watch with a printed dial. Anything above $900 is priced as if it were a genuine piece, which it is not.
What should you inspect before you pay?
- Ask for a side-profile photo. The Da Vinci case curves inward at the lugs, and flat copies are easy to spot.
- Request a video of the chronograph running. Confirm which subdial counts minutes and which counts hours.
- Check the date window font and magnification against reference photos.
- Look at caseback engraving depth and the reference number spacing.
- Confirm the return window in writing before shipping.
Do not assume water resistance. Gaskets on replicas are rarely tested, so keep the watch away from swimming and showers.
Is buying a replica legal in the US?
Selling counterfeit goods is illegal under US trademark law, and US Customs can seize inbound shipments of infringing watches. Buyers rarely face prosecution, but they do lose the item and the money.
Replicas also carry no manufacturer warranty, cannot be serviced by IWC, and have almost no resale value. Weigh those costs against the price of the copy.
Frequently asked questions
Does a replica Da Vinci IW376018 hold value?
No. Replica watches depreciate to near zero the moment they ship, while genuine Da Vinci chronographs trade on the secondary market at a real, if modest, level.
Will a watchmaker service a replica?
Some independent watchmakers will work on an Asian 7750 for a flat fee. Authorized service centers will refuse the watch outright.
What strap size fits the IW376018 case?
The genuine uses an integrated-style curved strap, so replica straps often fit only the replica case. Buy the strap from the same seller if you want a guaranteed fit.
