A fake Da Vinci IW376051 is a replica of the IWC Da Vinci Chronograph, a cushion-shaped steel watch with a case around 43 mm wide, two chronograph registers, and a sapphire crystal. Good replicas match the case profile, dial print, and strap hardware. Weak ones get the crown guards, subdial spacing, and date window shape wrong. Prices run from about $60 for a quartz build to $550 for a Swiss-movement version.
What Is the IWC Da Vinci IW376051?
IWC built the Da Vinci Chronograph on a cushion-shaped case, a break from the round Portugieser and Pilot lines. The family ran through the late 2000s with steel cases, leather straps or steel bracelets, and a chronograph layout that put elapsed minutes high on the dial and small seconds at 9 o'clock.
IW376051 is one reference inside that family. IWC changed dial colors, strap options, and movement details across the run, so confirm the exact spec list with the maker before you order a replica of it.
What Do Replica Makers Copy Well?
The case is the easiest part to clone. CNC milling from a steel block gives a replica the same rounded lugs and cushion profile as the original, and most factories now polish and brush those surfaces in the right places.
- Sapphire crystal with an anti-reflective coating on both faces.
- Dial print with applied steel markers and lume plots.
- Deployant or pin-buckle hardware with engraved branding.
- Caseback engraving in the correct reference and serial format.
Where Replicas Fall Short
Case thickness and crown guards
Replica cases often run 0.5 mm to 1 mm thicker than the original because the movement inside has a different shape. The chronograph pushers can sit too high as well, which changes the side profile on the wrist.
Dial details
Subdial spacing is the tell most buyers notice. A 7750-based replica stacks the chronograph counter at 12 against small seconds at 9, and that gap may not match the original. Date window size and the weight of the dial text are the next giveaways.
Movement finish
You will not see the movement while the watch is on your wrist, but you feel it. Winding resistance, pusher click, and the snap of a chronograph reset all come from the calibre inside. An Asian 7750 feels lighter on the crown; a Swiss 7750 from ETA feels tighter and starts with less travel on the pusher.
Replica Tiers and What They Cost
- Budget quartz, $60 to $120: correct look from arm's length, wrong weight, subdials that do not sweep.
- Mid-tier Asian 7750, $180 to $280: automatic winding, working chronograph, decent case and dial.
- High-end Swiss 7750, $350 to $550: cleaner finishing, closer dimensions, longer service life.
Prices move with exchange rates and factory batches, so treat these as ranges rather than fixed tags. Ask what movement is inside before you compare two listings, because a $200 quartz watch and a $200 automatic are not the same product.
How to Check a Fake Da Vinci IW376051 Before Paying
- Ask for photos of the case side and the caseback, not only the dial.
- Request a video of the chronograph starting, stopping, and resetting to zero.
- Confirm the movement name in writing.
- Compare subdial positions against a photo of the original reference.
- Check the lug width the seller lists against the original spec.
Strap and Bracelet Options
The IW376051 shipped on leather in most configurations, and replicas follow that pattern with alligator-grain or smooth calf straps. Steel bracelet versions exist, and the bracelet is where quality swings widest across factories.
- Leather: check stitching density and the buckle engraving.
- Steel: check for sharp edges on the links and a clasp that closes with a solid click.
- Spring bars: confirm the diameter, since thin bars rattle in oversized lug holes.
Questions Buyers Ask
Does a fake Da Vinci IW376051 keep good time?
A Swiss 7750 replica holds within a few seconds a day after regulation. Asian 7750 clones land between 10 and 20 seconds a day out of the box, and a watchmaker can tighten that for a small fee.
Can a jeweler spot it?
Yes, under a loupe. Dial print, engraving depth, and case finishing all show differences at 10x magnification. On the wrist, most people will not notice anything.
How long will it last?
Case and crystal hold up for years. The movement is the wear item, so budget for a service or a replacement calibre every three to five years of regular use.
Is the listed water resistance real?
Treat any rating as a claim, not a guarantee. Have a watchmaker pressure test the case before you swim with a replica.
What to Confirm With the Seller
Get the movement name, case diameter and thickness, lug width, and crystal material in writing before you pay. A seller who cannot answer those four points is guessing at what they stock.
Read the return policy as well. A swap or repair costs less than a watch that arrives with a dead chronograph or a stripped crown thread.
