Verdict: Buy the Real One, or Buy Nothing
If you are comparing a fake IW376073 against the genuine IWC, the honest answer is that the replica loses on every measurement that matters. Dial printing, subdial spacing, crown action, and caseback engraving are the four areas where the copy collapses under a loupe, a caliper, or even a bright phone light. A real reference holds value. A fake holds nothing. That said, the market keeps producing close copies, so you need to know what you are looking at before money changes hands.
Buy Fake IW376073: Replica Buyer's Guide
What Separates the Two
Dial and Printing
On the genuine piece, applied indices sit flat against the dial and every marker lines up with the printed track. Replicas pad-print the markers on some versions, which leaves a soft edge and a visible halo under magnification. Check the date window: real IWC fonts are crisp and the aperture edges are chamfered, while copies show a flat, stamped cut and a wider gap around the numeral.
Case, Bezel, and Crown
Run a fingernail across the case flank. Genuine IWC uses sharp, polished transitions that meet the brushed surfaces on a defined line. Fakes round that line off because the case is cast and hand-finished afterward. The crown should turn with light resistance and no wobble. A gritty or loose crown is the single fastest tell.
Movement and Caseback
Pop the caseback and the difference is immediate. The real movement shows perlage, blued screws, and a signed rotor with correct engraving depth. Copies use generic movements with stamped plates and painted lettering. Caseback text on a fake is often too large, too shallow, or set in the wrong typeface.
Weight and Balance
A real steel reference carries weight across the whole head. Fakes feel top-heavy because the case is overbuilt to hide a smaller movement, and the bracelet links rattle when you shake the watch near your ear.
Before You Compare: What You Need
- A 10x jeweler's loupe
- Digital calipers accurate to 0.01 mm
- A bright, directional light source
- The official reference specification sheet for the model
How to Check in 60 Seconds
- Photograph the dial straight on with your phone, then zoom into the printing.
- Measure case diameter and lug width against the factory spec.
- Turn the crown ten full rotations and feel for grit or slip.
- Inspect the caseback engraving depth with the loupe.
- Weigh the watch head on a kitchen scale and compare against the published figure.
- Ask for the service history and the original box and papers.
Options, Ranked
- Best: a used genuine IW376073 with full set and service records.
- Middle: the same reference from a dealer with a written authenticity guarantee.
- Last resort: a clearly labeled homage that copies the look without copying the name.
Counterfeit watches are illegal to import in most countries, including the United States, and they carry no warranty, no service support, and no resale value. If the price is far below market, the watch is not real.
