The top pick for most buyers is a top-tier fake Portugieser Automatic 42 with a 42.3 mm case, a working power reserve hand, and a smooth-winding automatic movement. The four criteria that decide whether you get that watch or a lookalike are case geometry, dial spacing, movement behavior, and strap quality. Everything below explains what to inspect, what each build tier gives up, and which one suits daily wear versus a safe-queen drawer.
Case size and profile
The original Portugieser Automatic 42 measures about 42.3 mm across with a thin bezel and a case height around 14 mm. That thin bezel is why the dial reads larger than the number suggests. A replica listed as 42 mm but photographed with a tall, blocky bezel is often riding a generic 41 mm or 43 mm case, and the mismatch shows up at the lugs and in the way the watch sits.
- Pro: A correct 42.3 mm case with a gentle lug curve balances on wrists from about 6.5 to 7.5 inches.
- Con: Budget builds use stock cases with thicker lugs and a deep caseback that pushes the watch off the wrist.
- Pro: Polished bezel and brushed case flanks are easy to check in seller photos under direct light.
- Con: Over-polished edges and soft lug tips are the fastest tell on a cheap case.
Dial layout and printing
The layout to demand is small seconds at 9, the power reserve scale at 3, and a date aperture at 6. Applied numerals and markers should sit above the dial surface with crisp edges. On weak replicas the subdial rings are shallow, the date font is too wide or too bold, and the printed minute track blurs under magnification.
- Pro: A correct dial gives you the proportion that makes this reference recognizable at arm's length.
- Con: Misaligned subdial rings and off-center date windows are common at the low end and cannot be fixed later.
- Pro: Silver, white, and blue dial variants all exist, so pick a finish you can verify against reference photos.
- Con: Sunburst finishes on cheap dials look flat indoors and grainy under direct light.
The power reserve hand: functional or painted on
This is the single detail that separates a serious build from a prop. The genuine watch runs seven days on one wind, so the reserve hand sweeps slowly across the scale. Many replicas carry a hand that is linked to nothing at all. Before buying, ask the seller for a short video: wind the watch, then watch the hand move as the mainspring fills. If it stays parked, treat the piece as decorative.
- Pro: A linked reserve hand is the clearest sign the movement is worth the higher tier.
- Con: Even linked hands track a shorter reserve, so expect a day or two of reading rather than a full week.
Movement, winding feel, and rotor noise
Ask which base movement the build uses and whether it is hand-wound or automatic. A clean wind should feel progressive, not gritty, and the rotor should spin without a rattle you can hear across a quiet room. Running seconds should sweep smoothly rather than tick.
- Pro: A well-finished automatic keeps time within a reasonable daily range and holds a wind overnight.
- Con: Low-grade movements drift, and servicing them is often more than the watch cost.
Crystal, caseback, and strap
Sapphire crystal with a light anti-reflective coating keeps the dial readable. The caseback engraving should be crisp and centered. Straps matter more than buyers expect: alligator-grain leather with stitched edges and a signed-style buckle finishes the look, while thin split leather gives it away in the hand.
Build tiers at a glance
Budget
- Pro: Lowest entry point, fine for a costume piece.
- Con: Static reserve hand, generic case, printed or poorly set markers.
Mid tier
- Pro: Better dial depth and a solid automatic movement.
- Con: Case proportions still off, strap is often an afterthought.
Top tier
- Pro: Closest case geometry, linked reserve hand, sapphire crystal, quality leather.
- Con: Highest cost, and stock moves fast, so sizes and dial variants sell out.
Which one fits your use case
For daily wear and office use, go top tier with a white or silver dial, because you will look at the subdials constantly and cheap printing becomes annoying. For occasional evening wear under a cuff, a mid tier build with a good strap is a sensible compromise. For a display piece or a gift gag, budget is enough, since nobody is timing the reserve hand. If your wrist is under 6.5 inches, try a 40 mm alternative instead of forcing the 42.
Pre-purchase checklist
- Confirm the listed case diameter is 42.3 mm, not a rounded 42.
- Request a video showing the reserve hand moving after a wind.
- Ask for macro shots of the date window, subdial rings, and markers.
- Check lug width against the strap so replacements fit.
- Confirm the return window and shipping terms in writing before you pay.
