The short answer: judge an imitation Portofino Small Seconds 39 by the dial and the small seconds gear train, not by the badge on the listing. Before you pay, ask the seller for four things tied to the exact unit you will receive: caliper photos of the case, a close-up of the subdial at 6 o'clock, a clear photo of the movement, and a timegrapher readout. A seller who supplies all four is worth a small premium over one who only posts factory renders. Treat the number 39 in the listing as a factory label rather than a specification, and confirm the real measurements yourself.
Why the subdial decides the purchase
The Portofino look depends on a clean, open dial with a small seconds register sunk at 6 o'clock. On a weak imitation, that subdial is where the shortcuts show first. The hand is often too short, so it stops before the printed track, or too long, so it grazes the numerals. The recess may be shallow and flat instead of properly stepped, and the concentric finish inside it may look like coarse sandpaper under a loupe. Ask for a short video with the watch running. The seconds hand should advance in small, even steps with no visible stutter or backward tick, and the hand should sit parallel to the dial rather than tilted.
What to look for
Dial and hands
- Leaf hands with a gentle curve and a clean center ridge, not flat stamped metal.
- Applied baton indices that are faceted, polished on the bevel and seated flush with no shadow gap.
- Printing that is single pass and crisp, with font weight matching the original and no ink bleed at the minute track.
- Sunburst finish that radiates from the center hole and shifts evenly as you tilt the watch, with no blotchy patches near the rehaut.
- Correct spacing between the subdial and the 6 o'clock position, since this is a common error on cloned dials.
Case and crystal
- A fully polished case with soft lug curves, no machining marks under the lugs and even reflection across the bezel.
- Sapphire crystal with inner anti-reflective coating, checked at an angle for milkiness or a blue tint.
- A signed crown that turns smoothly and pulls to setting without wobble.
- Deep, sharp caseback engraving rather than shallow laser etching.
Movement and strap
- Ask which movement is installed. Thin automatic small-seconds calibers keep the case slim; a standard movement with a bolt-on module usually adds height and can make the seconds hand jump.
- Request a timegrapher photo showing rate, amplitude and beat error in several positions.
- Leather strap with tight, even stitching, a soft lining and a buckle that matches the case finish.
Parameter bands for a sound example
- Case diameter: 37 to 39 mm depending on whether the seller measures the bezel edge or includes the crown.
- Case thickness: 9 to 10.5 mm. Anything past 11 mm usually means a modular movement.
- Lug width: 18 to 20 mm, confirmed in writing so replacement straps fit.
- Beat rate: 28,800 vibrations per hour on thin automatic bases, 21,600 on some small-seconds builds.
- Power reserve: 38 to 45 hours when fully wound.
- Rate: within plus or minus 15 seconds per day is realistic; ask for the actual reading, not a promise.
- Water resistance: treat any 30 m claim as splash only and never pressure test a replica.
Pitfalls that cost you money
- Listings built entirely from stock images with no dated timestamp or handwritten note.
- A case size that changes between the title and the description, which usually means the seller ships whatever batch arrived.
- Claims of Swiss origin with no movement photo and no marking visible on the rotor or bridges.
- No timegrapher data, or numbers that are suspiciously perfect across every position.
- Sellers who refuse to show the caseback or the strap underside.
- Payment requests through methods with no recourse if the watch arrives different from the photos.
Questions buyers ask
Is a 39 mm imitation the same as the original?
The classic Portofino small seconds model is a 37 mm watch, so a listing labeled 39 is either measured differently, built on a different case, or named loosely. Ask for caliper photos across the bezel and confirm thickness at the same time.

Which movement should I request?
A thin automatic small-seconds caliber gives the correct profile and a smoother subdial. A modular build is acceptable at a lower price point, but inspect the seconds hand carefully for stutter before you accept it.

Can I wear it in water?
No. Keep it away from showers, pools and salt water. The gaskets on replicas are not reliable and a leak will ruin the dial.
How do I inspect the small seconds on arrival?
Wind it fully, let it run for an hour and watch the subdial against a reference clock. The hand should sweep in consistent increments, and the rate should stay stable over 24 hours.
Should I pay extra for a Swiss-labeled movement?
Only if the seller shows the movement and the marking clearly. Otherwise put the money into a better dial, crystal and strap, which are what you actually see on the wrist.
