A fake IW371625 is a counterfeit copy of the IWC Portugieser Chronograph, a 41 mm stainless steel chronograph powered by IWC's in-house calibre 69355. The giveaway is usually the movement, not the dial: genuine examples run a column wheel chronograph with a 46-hour power reserve at 4 Hz, while many fakes hide a decorated Asian 7750 or a quartz module. Weight, thickness, and dial printing finish a close second when you inspect one in hand.
What is the IWC IW371625?
The IW371625 belongs to the Portugieser Chronograph family, a line that pairs a slim steel case with a clean two-register dial. Key specs are a 41 mm diameter, roughly 13.1 mm thickness, sapphire crystal on both sides, and 3 bar water resistance. The layout is fixed across the family: small seconds at 6 o'clock and chronograph minutes at 12, with a date aperture and applied numerals.
How do you spot a fake IW371625?
- Case thickness and profile: A counterfeit often measures 1 to 2 mm thicker because the cloned movement sits higher. The lugs should taper into a slim, flat caseband.
- Movement architecture: Ask for a clear, uncropped movement photo. Look for a column wheel near the crown and IWC's pawl winding parts, not a rotor stamped to mimic a 69355.
- Dial printing and subdials: Text should be crisp under magnification, and the subdial rings should sit perfectly concentric to their hands.
- Caseback engraving: Reference and serial numbers are engraved, not laser-etched, and the lines are sharp with consistent depth.
- Crown and pushers: Chronograph pushers should start, stop, and reset with a firm click. Mushy or grinding pushers point to a cheap module.
Why does the movement matter more than the dial?
Calibre 69355 is an in-house column wheel chronograph with a 46-hour power reserve and a pawl winding system. Column wheel actuation gives a light, precise pusher feel that a cam-actuated 7750 clone cannot match. It also drives the 4 Hz beat rate you can verify by listening to the escapement or timing the seconds hand over 60 seconds.
What quality tiers exist for IW371625 replicas?
- Entry tier: quartz or basic automatic, wrong thickness, painted subdials, and printed rather than applied indices.
- Mid tier: Asian 7750 with a decorated rotor plate, closer case profile, but pushers feel heavy and the rotor is loud.
- High tier: custom column wheel clones with correct subdial spacing, sapphire crystals, and gen-spec case dimensions. These cost several times an entry piece and still are not genuine.
How much should a real IW371625 cost compared with a fake?
Pre-owned genuine IW371625 examples trade in the mid four figures on the secondary market, and steel Portugieser Chronographs hold value well. Replica pricing runs from under one hundred dollars for entry pieces to several hundred for high-tier builds. A price far below market for a supposedly genuine watch is the single strongest warning sign.
Is it legal to buy or own a fake IW371625?
Counterfeit watches infringe IWC's trademarks, and customs agencies seize them at the border as infringing goods. Reselling a counterfeit as genuine carries civil and criminal exposure in most jurisdictions. A replica also carries no warranty and will never be serviced by IWC or an authorized watchmaker.
What should you check before paying for an IW371625 replica?
- Request a timestamped photo and a short video showing the chronograph running and resetting.
- Confirm the listed case diameter and thickness match the genuine reference.
- Ask which movement is installed and whether parts are available for service.
- Verify a return window and use a payment method with buyer protection.
