The best fake IW371422 alternative is a 40.9mm automatic Portugieser chronograph replica with a Swiss-style A7750 chronograph movement and a silver-plated dial, because it keeps the case proportions, subdial layout, and leaf hands that make the original easy to recognize. If budget matters more than movement feel, a Japanese quartz Portugieser chronograph is the sensible second choice. If you simply want the same wrist presence with a newer reference, the IW371605 replica is the closest swap.
Top pick: Swiss-grade automatic IW371422 replica
This is the version most buyers should start with. The IW371422 is defined by its 40.9mm steel case, thin bezel, applied numerals, and the twin subdial layout at 6 and 12 with the small seconds and 30-minute counter. A good replica reproduces all four, and the automatic movement gives the seconds hand the smooth sweep that a quartz copy cannot fake.
- Case size: 40.9mm across, about 12.3mm thick, so it wears close to the original
- Movement: automatic chronograph with running seconds, 30-minute and 12-hour totalizers
- Dial: silver-plated with rhodium-plated leaf hands and applied baton markers
- Crystal: domed sapphire with anti-reflective coating on both faces
- Strap: alligator-grain leather on a steel pin buckle
Check the subdial spacing before you buy. On a weak fake IW371422 alternative, the two counters sit too close to the center and the date window drifts off axis. On the better builds, the layout lines up with the original and the date sits where it should.
How the alternatives compare
1. Budget pick: Japanese quartz Portugieser chronograph
Same case shape, same dial design, roughly half the price. The trade-off is the ticking seconds hand at 6 o'clock and lighter overall weight. If you want the look for occasional wear, this is the value option. If you plan to wear it daily and care about feel, pay for the automatic.
2. Modern reference swap: IW371605 replica
The IW371605 keeps the 40.9mm case but adds the newer dial details, including the double box-frame date window and slimmer subdial rings. It reads slightly more contemporary on the wrist. Choose this if you want the Portugieser look without hunting a discontinued reference.
3. Cleaner dial: Portugieser Automatic IW500705 replica
No chronograph pushers, no subdials, just the power reserve indicator and small seconds at 3 and 9. The case grows to 42.3mm, which suits larger wrists. Pick it if the chronograph layout feels busy to you but you still want the Portugieser silhouette.
4. Smaller budget: Portofino chronograph IW3910 replica
A 42mm case, flatter bezel, and a more conventional three-counter chronograph layout. It costs less than a proper Portugieser build and wears smaller than the numbers suggest. The trade-off is that it looks like a different watch, so buy it for the style, not as an IW371422 stand-in.
5. Non-replica route: entry luxury chronograph
If the goal is a silver-dial chronograph on leather rather than a specific reference, a genuine entry-level Swiss or Japanese chronograph gets you a real warranty and service history. It will not match the Portugieser dial, but it removes the question of authenticity entirely.
What separates a good fake IW371422 from a bad one
- Dial printing: sharp, evenly spaced text with no bleeding at the edges
- Hands: leaf-shaped, correctly curved, with a polished bevel that catches light
- Pushers: firm start, stop, and reset with a clean snap, no mush
- Case finishing: brushed flanks, polished bezel, crisp transitions between the two
- Weight: a steel automatic should feel dense, roughly in the 80 to 90 gram range on leather
- Engraving: caseback text should be deep and legible, not laser-etched and shallow
Buying checklist
- Confirm the case size is listed as 40.9mm, not a rounded 41mm or 42mm.
- Ask which movement is inside and whether the chronograph functions actually work.
- Request real photos of the exact watch, not catalog renders.
- Check the date font and alignment in a close-up shot.
- Confirm the strap width at the lugs is 20mm so replacements are easy to find.
FAQ
Is the IW371422 still in production?
No. The reference has been phased out of the current catalog in favor of newer Portugieser chronograph references, which is one reason replicas and pre-owned examples get so much attention.
What movement should a good replica use?
An automatic chronograph movement based on the Valjoux 7750 architecture. It gives you the correct subdial functions and a sweeping seconds hand.
Can a quartz version pass as the real thing?
At arm's length, yes. Up close, the ticking small seconds is the giveaway. If that detail bothers you, go automatic.
