Choosing between a replica IW371482 and the original IWC Portugieser Chronograph comes down to what you value most: exact provenance or everyday look and feel. For most shoppers who want the iconic 41mm Portugieser profile without the collector-level commitment, the high-grade replica is the first pick. This comparison breaks down the details so you can decide which option fits your wrist and your priorities.
Key Features
- 41mm stainless steel case with the same stepped bezel and slim lugs as the original
- Blue sunburst dial with twin chronograph subdials and applied Arabic numerals
- Sapphire crystal with anti-reflective coating for clear legibility
- Automatic chronograph movement with a smooth sweeping seconds hand
- Embossed alligator-style leather strap with a signed pin buckle
- Chronograph pushers with crisp start, stop, and reset action
- Water resistance rated for splashes and daily wear
- Available with either a display caseback or a solid engraved caseback
In terms of materials, the replica IW371482 uses 316L stainless steel for the case, matching the original's non-precious metal option. The dial is brass with a sunray finish, and both versions use sapphire crystal, though the original adds a double anti-reflective coating. The main difference is the movement: the original runs IWC's in-house calibre 69355 with a 46-hour power reserve, while the replica typically houses a modified ETA 7750 or a Seagull chronograph. Case thickness is about 12.5mm on the replica versus 12.3mm on the original, a difference you will not notice on the wrist. The replica strap is genuine leather with an alligator emboss, while the original comes with hand-finished alligator.

Is the replica IW371482 water resistant?
The replica is rated for everyday splash resistance, similar to the original's 30-meter rating. It handles rain and hand washing, but you should not swim or shower with either version.
How close is the replica movement to the original?
The replica uses a reliable automatic chronograph movement that keeps good time, but it does not have the in-house finishing or the 46-hour power reserve of the original calibre 69355. For casual wear, the difference is minimal.
Which one should you buy first?
If you want the Portugieser look for daily wear, start with the replica IW371482. If you are building a collection and value provenance, save for the original.
