The best fake IW371479 is a 1:1 replica of the IWC Portugieser Chronograph that copies the 40.9 mm case, the two-register dial, and the crown and pusher layout of the genuine watch. Top-tier builds run a modified A7750 automatic chronograph, use sapphire glass with inner anti-reflective coating, and match the original case height within half a millimeter. Cheap copies give themselves away on three details: flat dial printing, uneven subdial spacing, and mushy chronograph pushers.
What is the IW371479?
The IW371479 sits inside the IWC Portugieser Chronograph family, a line built around a clean dial with small seconds at 6, a 30-minute chronograph counter at 12, and a date window at 3. Watches in the 3714 generation measure 40.9 mm across and 12.3 mm tall, and they run the 79350 calibre, a Valjoux 7750 base modified by IWC. Later 3716 references grew to 41 mm and 13.1 mm and switched to the in-house 69355.
The design has few places to hide. Applied indices, leaf-shaped hands, and a thin bezel leave every flaw in plain view, which is why a decent replica needs precision work on the dial rather than a busy case.
What separates the best fake IW371479 from a cheap copy?
Four parts of the watch decide the quality grade, and each one shows up in photos once you know what to look for.
How to Get Fake IW371479 Watches
- Movement. An automatic A7750 with a working chronograph sweeps at 28,800 vibrations per hour. Quartz versions tick once per second and fake the 12 o'clock counter with a static hand.
- Case. Look for 316L stainless steel with a polished bezel, brushed flanks, and a height close to 12.3 mm. Thick, slab-sided cases sit high on the wrist and read as fake from a meter away.
- Crystal. Sapphire with an inner anti-reflective coating gives a clear dial with almost no glare. Mineral glass adds a blue tint and scratches within weeks.
- Dial and hands. Indices should be applied, not painted, and the minute track should line up with the subdial rings. Leaf hands need the right length and a clean rhodium or blued finish.
Which movement should you pick?
Three movement types appear in replica IW371479 listings, and they behave in very different ways.
- A7750 automatic. The default choice for serious replicas. It has a working chronograph, a smooth sweep, and a pusher feel close to the original. Service is easy because any watchmaker who handles ETA clones can work on it.
- Seagull ST19 hand-wound. A column-wheel chronograph with a clean sweep and a slim profile. The trade-off is winding every morning and a louder rotor-free movement.
- Quartz. Light, cheap, and accurate for timekeeping, but the chronograph runs on a stepping motor and the subdials sit in the wrong place.
How do you check a fake IW371479 before you pay?
Ask for a video, not just still photos. A short clip of the chronograph starting, stopping, and resetting tells you more about a watch than twenty glossy shots. Ask the seller to match the exact dial color and strap of the reference you want, because many listings use stock photos of a different variant.
Case and crystal
- Check the lug width (20 mm on the 3714 family) and confirm the strap lines up without gaps.
- Look at the crown and pushers from the side. They should sit flush with the case band, not proud of it.
- Ask for a reflection test. Genuine sapphire shows almost no color when a light source hits it at an angle.
Dial and date
- Zoom on the printed text. Letters should be crisp with no bleeding or double edges.
- Check the date font. A bold or oversized number is one of the most common flaws on mid-tier copies.
- Compare subdial ring positions. Both should sit on a vertical line through the center of the dial.
Chronograph and winding
- Start the chronograph and watch the sweep. A stutter means the movement needs service or is low grade.
- Reset the chronograph. The hands should snap back to 12 without drifting.
- Wind the crown and listen. Grinding or a gritty feel points to worn keyless works.
Price tiers for replica IW371479 watches
Price tracks movement quality, finishing, and quality control rather than the brand name on the dial.
- Under $100. Quartz or low-grade automatic. Buy only if you want a visual prop and nothing more.
- $150 to $300. Mid-tier A7750 builds with mineral glass or basic sapphire and average dial printing.
- $300 to $500. The sweet spot. Sapphire crystal, decorated movement, applied indices, and a correct case profile.
- Above $500. Sellers charge for super clone labels here, but few IWC replicas justify the price because the market for this model is smaller than the Submariner or Daytona market.
FAQ
Does the best fake IW371479 have a working chronograph?
Yes, if it runs an A7750 or a Seagull ST19. Both drive the chronograph hands through the movement, so start, stop, and reset work the way they do on the genuine watch. Quartz copies often show fixed subdials instead.
How long does a replica IW371479 last?
An A7750 used with care runs for years, though a service every three to five years keeps the chronograph accurate. Quartz copies last until the battery or the plating gives out, which is often two to three years.
Is it legal to buy a fake IW371479?
Rules vary by country, and customs in the United States and the European Union seize counterfeit goods. A replica is not a genuine IWC, carries no brand warranty, and has no resale value.
Care tips for a replica Portugieser Chronograph
- Keep it away from water even if the case back says 50 meters. Replica gaskets are not tested.
- Press the pushers only when the chronograph is running or reset, and never reset while it is moving.
- Store it on a winder or wind it twice a week if you want to keep the date and time set.
- Clean the case with a soft cloth and avoid solvents near the crystal gasket.
Bottom line: spend in the $300 to $500 range, insist on an A7750 or ST19 movement, and judge the seller on the quality of their videos rather than their marketing copy.
