The pick, up front
The Longines Master Collection small-seconds automatic is the alternative I would buy. It is a real Swiss watch, it costs roughly $1,800 to $2,500 depending on the reference, and it delivers what people chase in the Portugieser: a thin steel case, a wide clean dial, a subdial at six and hands you can read from across a table. Longines sells through normal dealers, so service and warranty are not a gamble.
What the search term really means
Listings titled "Portugieser Automatic 31" almost always describe the same layout. IWC's Portugieser Automatic is a dress watch with a railroad minute track, applied numerals, leaf hands and small seconds. The "31" in those listings tends to be a jewel count copied from a spec sheet, not a model number. So the search is about a look, not a specific movement.
That matters, because the counterfeit version of this watch runs $250 to $500. For that money you get a case and dial that photograph well, a movement nobody will service, and water resistance that is decorative. Everything below has a name, a movement you can repair, and resale value that is not zero.
Portugieser Automatic 31 Replica Review: The Ultimate Guide
Why Longines wins
Three things decide it. Size, availability and dial discipline. The Master Collection small seconds comes in the 38.5mm to 40mm range, which is where most wrists want a dress watch. You can try one on in a mall. And the dial is quiet: no chronograph, no date window cutting into the markers, no busy text. Most versions use Roman numerals or stick markers instead of Arabic, so it is not a clone of the Portugieser face. Same idea, different accent.
Three more options, ranked
- Stowa Marine Original. The closest dial match to a Portugieser. Arabic numerals, railroad track, small seconds at six, blued hands. Around $1,200 direct from Germany. The catch is you buy blind and wait for the build.
- Nomos Tangente 38. Bauhaus rather than Portuguese, but it shares the thin case, the small seconds and the understated face. Two to three times the price of the Longines, in-house movement, excellent finishing.
- Orient Bambino Small Seconds. Under $300. Domed crystal, in-house automatic, small seconds at six. It is the cheapest way to get this dial layout without touching a counterfeit, and it works fine as a first dress watch.
Two other routes are worth knowing. Pre-owned IWC is real: a used Portugieser Chronograph or a Mark series pilot can land near $3,000, and you own the actual brand. Chinese homages from brands like San Martin or Sugess are the other route, usually $150 to $350, and they put their own name on the dial. That name is the line between an homage and a fake.
What I check before buying
- Case diameter and lug to lug. A 40mm dial with 50mm lugs wears bigger than the number suggests.
- Movement and service path. Sellita, ETA, Miyota and Seiko movements can be fixed anywhere. In-house is fine when the brand has a real service network.
- Water resistance. 30m means splashes only. 50m or better if you want to wear it daily.
- Return window. Anything bought sight unseen should come with 14 days minimum.
Bottom line
If you want the Portugieser look without paying Portugieser money, the Longines Master Collection small seconds is the safe call. Stowa gets you closer on dial details, Nomos gets you better watchmaking, and Orient gets you in the door for a few hundred dollars. All four beat a replica on the one metric that matters after year one: whether anyone will still fix it.
