The short answer
The reference IW371495 is the IWC Portugieser Chronograph in stainless steel with a silver-plated dial and gold-plated hands and markers. Anything sold as a replica, fake, or first copy of that reference is a counterfeit. It copies the silhouette, not the watch. A genuine IW371495 runs the in-house calibre 69355, a column-wheel chronograph movement with roughly 46 hours of power reserve, inside a 41mm steel case. Copies range from obviously crude to convincing across a table, and almost none of them share a single part with the original.
What the IW371495 is
IWC released the modern Portugieser Chronograph as a 41mm piece with a slim bezel and a clean, two-register layout. The 495 reference pairs a steel case with a silver dial, applied indices, and blued or gold-toned hands depending on the variant. The movement is visible through a sapphire caseback, which matters a lot when you are trying to tell real from fake. The Portugieser line traces back to the 1930s, when IWC built a large pocket-watch movement into a wristwatch case for two Portuguese merchants. That history is part of why the design reads as understated rather than flashy, and part of why it gets copied so often.

Why this reference attracts copies
Clean dials are easy to photograph and easy to imitate at a glance. There are no complex curved surfaces, no unusual materials, no wild colorways. A two-register chronograph with a silver dial and thin hands photographs well on a marketplace listing, and buyers browsing on a phone see a familiar shape. Add a recognizable brand name and the listing does the rest of the work.
The tiers you will run into
- Budget fakes. Quartz or basic automatic movements, printed dials, plated cases that wear through in months. Subdials often do not function as chronograph registers at all.
- Mid-tier copies. A generic Chinese automatic chronograph movement, decent case polishing, and a dial that looks right in photos but falls apart under a loupe. Fonts are usually slightly wrong and the date window sits off-center.
- So-called super clones. These get close on dimensions and finishing. They still use a third-party movement, which means the caseback view never matches the real calibre 69355, and the service network does not exist.
How to spot a fake IW371495
- Caseback. Look at the movement. A genuine 69355 has specific bridge shapes, engraving, and finishing. Copies show a generic rotor and mismatched decoration.
- Dial printing. Genuine IWC text is crisp and evenly spaced. Fakes show thick or fuzzy lettering, and subdial rings that are slightly too wide or too narrow.
- Hands and indices. Real gold-plated applications have depth and sharp edges. Copies look flat and reflect light in dull patches.
- Case finishing. Brushed and polished transitions on the real case are clean and consistent. Copies blur the line between the two.
- Reference engraving. The number between the lugs should match the papers and the listing. Sellers often reuse casebacks across models.
- Weight and feel. A steel IW371495 has a density you notice. Many fakes feel light or slightly hollow.
- Papers and box. Cross-check serial numbers against the warranty card. Nothing is easier to fake than cardboard.
What sellers leave out
No IWC service center will touch a counterfeit. That means no movement service, no gasket replacement, no water resistance testing. Water resistance claims on replica listings are marketing copy, not specifications, and a leak ruins the watch and possibly your phone in the same moment. Resale value on a fake is close to zero, and importing one into the United States is a customs matter, not a gray area. Counterfeit trademarked goods are subject to seizure at the border.
If you want the look on a budget
Buy a watch that does not pretend to be something else. There are plenty of two-register chronographs from mainstream brands that give you the same clean layout, a real warranty, and a serviceable movement. If the Portugieser specifically is the goal, a genuine pre-owned example in the mid four figures holds value, comes with a real movement, and can be serviced for decades. That is a different purchase than a copy, and it is the one most people end up wishing they had made first.
