A fake IW371631 replica is a copy of the IWC Portugieser Chronograph, built to match the look of the original at a small share of its price. Most versions run a quartz or automatic chronograph movement inside a steel case, with dial printing, hands, and straps styled after the genuine reference. Quality varies between sellers, so the movement type and the dial details matter more than the listing photos.
What defines the IW371631 look?
The IW371631 sits in the IWC Portugieser Chronograph family, a line with a wide, clean dial and a vertical subdial layout. A good copy matches the case profile, the thin bezel, and the leaf-shaped hands before anything else. Dial colors and strap options change across this reference range, so compare any listing against official photos of the exact variant you want.

Details to compare side by side
- Case: polished steel, about 41mm across and close to 13mm thick, with slim lugs.
- Subdials: chronograph minutes at 12, running seconds at 6, stacked on one vertical line.
- Hands: thin feuille (leaf) hands, not the thicker baton style used on other IWC lines.
- Crystal: domed sapphire with anti-reflective coating on the inside face.
- Strap: alligator-grain leather with a pin buckle or a folding clasp.
What does "first copy" mean for an IW371631?
"First copy" is retail slang for the top replica tier, the version built with the closest match to the original case, dial, and movement layout. It does not mean a genuine watch, and it does not mean an official second-quality unit from the brand. Sellers use the term to separate their best stock from cheap quartz copies.
How do replica grades differ?
Fake IW371631 watches fall into three broad groups, and the gap between them shows up in the movement, the dial finish, and the case profile. Price tracks those three things more than anything else. Ask which grade a seller offers before you compare two listings.
- Budget quartz: mineral glass, printed dial, subdial hands that tick once per second. Often the thinnest and lightest of the group.
- Mid automatic: a Japanese or Chinese automatic chronograph, sapphire glass, sharper printing. Subdial spacing can still sit off center.
- Clone grade: an automatic chronograph built close to the original layout, with a decorated rotor and deeper caseback engraving. Heavier, and the closest match on the wrist.
Prices move with seller and stock, but general market ranges look like this: budget quartz copies land near $60 to $90, mid automatic versions run about $150 to $250, and clone grade sits above $300. A price far below those bands points to quartz inside. A price far above them does not buy a better movement on its own.
How to spot a weak fake IW371631
- Subdials drift out of line with the dial center, or sit too far apart.
- Printing looks thick or blurry, or the font weight is wrong.
- The date window sits crooked, or the date font looks generic.
- The case is too thick, so the watch rides high on the wrist.
- Pushers feel gritty, and the reset button fails to snap back.
- The crystal is mineral glass with a rainbow sheen in daylight.
- Strap stitching is uneven, or the leather feels like plastic.
- Caseback engraving is shallow, off center, or misspelled.
Does the chronograph work on a replica?
Most fake IW371631 watches have working pushers, but the movement inside decides how they feel. A quartz copy starts and stops with a firm click, while a mechanical clone gives a softer push and a smoother sweep. The running seconds subdial at 6 is the easiest tell: quartz ticks once per second, a mechanical movement sweeps.
What should you check before you order?
- Ask for real photos and a short video of the actual watch, not stock images.
- Confirm case diameter and thickness so you know how it wears on your wrist.
- Ask which movement is inside, and whether the chronograph resets to zero.
- Check the return window and who pays return shipping.
- Read the water resistance claim, then treat the watch as splash-proof at best.
- Check the payment method and buyer protection before you send money.
How do you care for a first copy IW371631?
Keep the watch away from hot water, soap, and steam, since gaskets on copies are the first part to fail. Wipe the case with a soft cloth and store it on a dry surface. On a mechanical version, wind it at the same time each day and have it serviced when the chronograph starts to lag.
Frequently asked questions about fake IW371631 watches
Is a fake IW371631 worth buying?
It can be, if you want the Portugieser look without the price of the original and you accept that the movement, the finishing, and the resale value will not match it. Buy the best grade you can afford instead of the cheapest listing you find.
Can a watchmaker tell a replica IW371631 from the real thing?
Yes. Most watchmakers can tell once the caseback comes off. Movement finishing, engraving depth, and dial printing are the usual giveaways.
How long do replica IW371631 watches last?
Quartz versions often run for years with a battery swap, and mechanical copies last as long as the movement is serviced. The strap and gaskets wear out first.
Do replica IW371631 watches hold value?
No. Copies sell at a loss on the secondhand market, so buy one to wear, not to store.
