What is a faux Portugieser 39mm?
A faux Portugieser 39mm is a replica of IWC's Portugieser line built with a case that measures about 39mm across. That size sits between vintage dress watches and the modern 40mm to 42mm Portugieser references, so it fits wrists that find the full-size model bulky. Sellers use faux and replica as synonyms, and the 39mm figure is a listing convention rather than an official factory reference.
The genuine family is defined by a wide, open dial, thin bezel, applied numerals, and leaf-shaped hands. A good replica carries all four traits at a smaller diameter, which is why the 39mm version attracts buyers who want the look without the bulk.
Why do listings say 39mm when IWC catalogs 40mm and up?
IWC sizes the Portugieser Automatic 40 at a 40.2mm case, so any 39mm figure comes from the replica trade, not the catalog. Makers often shave a millimeter to reuse a smaller case blank or to appeal to buyers in Asia and Europe who prefer compact dress watches. Treat the number as approximate and confirm the real measurement with calipers or a seller photo on a ruler.
Understanding Fake Portugieser 39mm Replicas
What should you inspect on the case and dial?
- Case thickness: ask for a side profile photo. Anything above roughly 11mm looks slab-sided next to the genuine watch.
- Dial print: check that the minute track is crisp and the text weight matches across both lines.
- Applied numerals: they should sit flush with sharp, polished edges and no glue shadow.
- Hands: leaf hands need a clean curve and even lume fill on both halves.
- Caseback engraving: deep, even lettering with correct reference text placement.
Which movement should you expect at this size?
Most 39mm examples run a Miyota 9015, a Seagull automatic, or a clone of an ETA 2892. A thin automatic matters here because a thick movement forces a tall caseback and ruins the dress-watch profile. Ask which calibre is installed and whether the rotor is decorated or plain, since plain rotors usually signal a budget build.

Should the small seconds sit at six o'clock?
On the classic Portugieser layout, yes, and the subdial should be centered with even spacing from the dial edge. A subdial that drifts off center or shows a stamped rather than recessed track is a clear sign of a low-grade build.
How does a 39mm replica wear compared with the genuine watch?
The smaller case reads more casual on a 7-inch wrist and works under a cuff, while the genuine 40mm model carries more presence. Lug-to-lug length matters more than diameter, so request that measurement before you commit. A 39mm watch with long lugs can still overhang a narrow wrist.
What price range is reasonable?
Expect roughly 200 to 450 US dollars for a solid 39mm build with a reliable Japanese or Swiss-clone automatic movement. Below 150 dollars you usually get a stamped dial, a noisy rotor, and plating that fades within months. Above 500 dollars you are paying for a name, not better finishing, unless the seller documents Swiss assembly and parts.
How do you spot a weak build inside a good listing?
Stock photos and no macro shots are the biggest warning sign, since sellers with quality pieces show close-ups of the dial and crown. Ask for a video of the seconds hand sweeping and a shot of the caseback threads. A seller who refuses both is not worth the risk.
FAQ
Is a 39mm faux Portugieser close to genuine dimensions?
It is slightly smaller than the 40.2mm Portugieser Automatic 40, so it wears a touch neater but keeps the same dial proportions.
Can a watchmaker service a replica Portugieser?
Yes, if the movement is a Miyota, Seagull, or ETA clone, since most shops stock those parts. Ask about the calibre before buying.
Does the smaller case hurt water resistance?
Not by itself, but most replicas seal to 30m at best. Avoid swimming and keep the crown screwed down.
