Top pick: a Portugieser-style automatic in the 41mm to 43mm range, with a bi-compax dial, applied Arabic numerals, sapphire on both sides, and a seller who will send caliper photos of the exact unit before shipping. The 46mm figure in your search deserves scrutiny first. Genuine Portugieser cases sit around 41mm for the Chronograph and roughly 42mm for the Automatic, while 46mm is the Big Pilot's territory in the IWC lineup. Criteria used here: honest case measurements, a movement whose layout matches the dial, dial furniture quality, crystal and anti-reflective coating, caseback detail, and strap hardware.

The 46mm question: fantasy size or measuring error
Replica listings reuse numbers loosely. A watch advertised at 46mm is usually one of three things: a fantasy oversize case that never existed in the genuine catalog, a measurement taken across the crown rather than the case flanks, or a listing that borrowed specs from another model entirely. Ask the seller for a photo of calipers across the case at 9 and 3 o'clock, crown excluded, plus a thickness reading. A trustworthy seller sends both within a day. One who answers with a stock photo or a claim of "1:1 Swiss made" is telling you what you need to know.
If you genuinely want a 46mm wrist presence, buy a Big Pilot-style replica, which is legitimately that size, instead of forcing a Portugieser into a dimension it does not occupy.
Movement and dial layout
The classic Portugieser Chronograph is bi-compax: two subdials stacked at 12 and 6, running seconds below and a 30-minute counter above, with the date at 3. A stock Asian 7750 is tri-compax, so a dial with a third subdial at 9 is not following the reference. That single detail separates a careful build from a parts-bin assembly.
- Pros of a 7750-based chronograph: proven architecture, easy servicing for a watchmaker, pushers with real feel.
- Cons: thicker than the genuine, rotor noise on cheaper examples, subdial spacing that betrays the module.
- Pros of a three-hand automatic: simpler, thinner, fewer failure points, closer to the hand-wound reference profile.
- Cons: no chronograph function, and the date change can be abrupt on low-tier movements.
Check that the chronograph resets to zero cleanly and that the seconds hand sweeps rather than ticks in one-second jumps. A ticking hand means quartz, whatever the listing says.
Case, dial, and finishing
Portugieser cases are largely polished with slim lugs and a thin bezel, so flaws show. Look for uneven polishing around the lug undersides, a crown that sits off-center, and pushers at different heights. On the dial, the numerals should be applied metal with crisp edges and consistent height, not printed decals. The leaf hands should be flat and evenly finished, with no paint creep at the tips.
Crystal matters more than most buyers expect. Double-sided anti-reflective coating gives a blue or purple wash under light that the genuine does not have. Single-sided inner coating reads closer to correct.
Red flags in listings
- The same photo appears on three other storefronts with different names.
- No macro shots of the caseback engraving or the clasp.
- Water resistance claims of 50m or more without any pressure-test documentation.
- Prices far below what the described movement costs wholesale.
- Reluctance to send a short video of the second hand sweeping.
Matching the watch to your use case
First replica, worn often: take the three-hand automatic. Fewer complications, less to go wrong, and the thin profile sits better under a cuff.
Accuracy-focused collector: the bi-compax chronograph with a correct subdial layout. Accept the extra thickness as the trade for the function.
Large wrists, 46mm preference: skip the Portugieser and shop a Big Pilot-style case, where the size is authentic.
Dress watch duty: prioritize the strap. A signed deployant and alligator-grain leather with tight stitching does more for the look than any dial upgrade.
Inspection checklist on arrival
- Measure the case yourself with calipers and compare to the listing.
- Wind 30 turns and check the power reserve holds overnight.
- Run the chronograph start, stop, and reset five times.
- Check the date flips at midnight, not at 11:40 or 1:20.
- Look at the crystal edge for coating delamination.
- Confirm the strap stitching is even and the buckle engraving is deep, not lasered shallow.
A replica at this level is a finishing exercise. The case diameter printed in a listing means little until someone puts calipers on the actual watch, so make that measurement the first condition of any purchase.
