What is the replica IW3717?
The replica IW3717 is a counterfeit copy of the IWC Portuguese Chronograph, a two-register chronograph with a clean dial, leaf hands, and applied Arabic numerals. The genuine reference line measures about 41 mm across and 12.3 mm thick in stainless steel, and IWC has produced it in various forms since the 1990s. Replica makers copy the outside closely and substitute a third-party movement inside.
How close is a replica IW3717 to the real watch?
A decent replica reads correctly from arm's length. The gaps appear when you look at the details.
- Dial: printing is softer, and the subdial rings often sit a fraction off center.
- Crystal: most copies use flat or lightly domed sapphire with weaker anti-reflective coating.
- Case: edges are over-polished and the lugs run slightly thick.
- Movement: an Asian 7750 with a decorated rotor instead of the IWC calibre 79350.
- Strap: embossed leather instead of genuine alligator.
Which movement is inside a replica IW3717?
Nearly every automatic replica IW3717 uses a Chinese-made clone of the Valjoux 7750. The genuine watch runs IWC calibre 79350, itself a heavily reworked Valjoux 7750, so the architecture matches even when the finishing does not. That shared base is why the case proportions and subdial positions hold up so well.
Quartz versions
Budget sellers fit a quartz module with faux subdials. These keep time accurately, but the seconds hand ticks and the case usually feels thin and light.
Automatic versions
Mid-tier and high-tier replicas use the Asian 7750 at 28,800 vph with a 40 to 44 hour power reserve. The chronograph functions, though pusher feel is stiff and reset can be imprecise.
What should you check before buying?
- Measure the case. Anything under 40 mm or over 42 mm will look wrong on the wrist.
- Confirm the subdial layout: running seconds at 6 o'clock, chronograph minutes at 12 o'clock.
- Ask for real photos rather than catalog renders, with a ruler or coin in the frame.
- Check for visible anti-reflective coating. A blue or purple sheen on the crystal is a good sign.
- Get the movement type confirmed in writing, since quartz and automatic listings look identical.
- Ignore any seller promising 10 ATM water resistance. Replicas rarely beat splash protection.
What does a replica IW3717 cost?
Quartz copies sell for roughly $80 to $150. Automatic Asian 7750 versions run about $200 to $350. High-grade replicas with sharper dial printing, better sapphire, and a decorated movement reach $400 and up.
Is buying a replica IW3717 legal in the US?
Not strictly. Importing counterfeit goods that carry a trademark is prohibited under 19 U.S.C. 1526, and U.S. Customs can seize a shipment even when it is meant for personal use. Sellers also rarely back the watch with a real warranty, so any repair cost lands on you.
Frequently asked questions
Is the replica IW3717 water resistant?
Treat it as splash resistant only. Gaskets on replicas are usually poor and the caseback is often not sealed properly.
Can a watchmaker service a replica IW3717?
Yes, if it carries an Asian 7750. Many independent shops will service a 7750 clone, though some decline replica work outright.
Does the replica IW3717 have a date window?
No. The Portuguese Chronograph dial stays clean, with two subdials and no date aperture.
How long does an Asian 7750 last?
With regular wear, expect five to eight years before it needs a service or replacement. Dust and hard chronograph use shorten that window.
