A replica IW371768 is a copy of IWC's 41 mm Portugieser Chronograph, and the versions worth buying get four things right: the 41 mm steel case profile, the two-register dial layout, the slim chronograph pushers, and a movement that places the sub-dials correctly. Expect to pay roughly $230 to $650 depending on movement and finishing, with sapphire crystal and a 7750-based automatic chronograph inside.
What is the replica IW371768?
The reference belongs to IWC's Portugieser Chronograph family: a 41 mm steel case, a clean two-register dial with running seconds at 6 and a 30-minute totalizer at 12, and a thin bezel that makes the watch wear wider than the numbers suggest.
Replica factories copy that silhouette. The better ones also match the printed track, the feuille-style hands, the 20 mm lug width, and the engraved caseback.
Which specs should a good replica match?
- Case: 41 mm diameter, roughly 13 mm thick, brushed flanks with polished bevels
- Dial: two registers at 12 and 6, applied numerals or printed markers depending on variant
- Crystal: domed sapphire with anti-reflective coating
- Movement: automatic chronograph, 46-hour-class power reserve on the genuine
- Water resistance: rated 30 m on the original; replicas vary and are splash-resistant at best
- Lug width: 20 mm, so genuine-spec straps fit
How much does a replica IW371768 cost?
Three tiers cover most of the market. Price tracks the movement, the dial print quality, and the case finishing, not the box it ships in.
- Entry, $80 to $180: quartz or basic automatic, mineral glass, sub-dial rings printed too close to the center
- Mid, $200 to $350: 7750-based automatic, sapphire crystal, clean dial print, average hand finishing
- Top, $380 to $650: modified 7750 with decorated bridges, correct sub-dial spacing, sharp case bevels, quality leather or steel bracelet
What separates a $250 replica from a $600 one?
Dial execution and case finishing. On the better build the sub-dial rings are recessed and correctly spaced, the printing stays crisp under a loupe, and the lugs show a real bevel instead of a soft edge.
Which movement should you choose?
A 7750-based automatic gives the correct sub-dial positions and a smooth sweep. Most watchmakers who service chronographs can work on it, and parts are easy to source.
Quartz versions are thinner and cheaper, but the seconds hand ticks, which is the fastest tell at arm's length. Skip them if the illusion matters to you.
How do you check a replica IW371768 before it ships?
- Request a live video, not stock photos, with the chronograph started and reset.
- Confirm the sub-dial centers sit on the 3 to 9 axis and below the main hands.
- Check date window alignment and font at 3 o'clock if your variant has one.
- Inspect caseback engraving depth and rotor decoration.
- Verify lug width with calipers: 20 mm on the genuine spec.
- Ask for a timing readout; plus or minus 15 seconds a day is acceptable here.
Frequently asked questions
Does the replica keep the 30 m water resistance?
Treat it as splash-proof only. Gasket quality varies between units and sellers rarely pressure-test each watch, so keep it out of pools and showers.
Can a jeweler tell it is a replica?
Across a table, no. Under a loupe, the tells are hand finishing, print sharpness, and rotor engraving. A watchmaker who opens the caseback will know in seconds.
Do genuine IWC straps fit?
Yes, if the lugs are cut to the 20 mm spec, which the better replicas do. Any 20 mm aftermarket strap is the safest fit.
Bottom line
Buy the mid or top tier, insist on live video before payment, and budget for a service within two years. The replica IW371768 looks convincing at arm's length when the dial and case finishing are right.
