Buy the movement first, the case second, and the dial third. On a counterfeit Portofino Chronograph, the detail that separates a wearable replica from a disposable one is what drives the hands: an automatic chronograph built on a Valjoux 7750 base, with the subdials at 12, 6 and 9 and the date at 3. Confirm the movement before anything else, then confirm the case lands near 42 mm wide and about 13.5 mm thick, then check that the top subdial counts 30 minutes rather than 60. Strap stitching, rotor engraving, and box contents are a distant fourth, because none of them affect how the watch runs after month two.

Why this model is hard to copy well
The Portofino Chronograph is a dress watch with a chronograph movement inside, which leaves no room to hide. The genuine case is thin for a 7750-based watch, so counterfeiters who drop a stock 7750 into a generic case end up 1 to 2 mm too thick. The dial is also clean: applied markers, thin leaf hands, and three recessed counters. Any sloppiness in printing or hand finishing shows immediately at arm's length. There is no rotating bezel, no busy texture, and no rubber strap to distract the eye.
What to look for
Movement and subdial layout
A 7750-derived chronograph places running seconds at 9, the 30-minute counter at 12, and the 12-hour counter at 6. The date sits at 3. A replica with center running seconds, a 60-minute totalizer at 12, or a date at 4:30 is using a different movement and will feel wrong in the hand. Ask for a photo of the movement with the caseback off, or at minimum a video of the chronograph starting, stopping, and resetting to zero in one crisp snap.

Case proportions and thickness
Measure with calipers if you can, or ask the seller for a measurement photo next to a ruler. Thin cases are expensive to make and cheap replicas rarely bother. A slab-sided case that sits tall on the wrist is the clearest tell.

Dial printing and hands
Look for crisp, raised markers with clean edges, a thin date frame, and hands that reach close to the minute track. Flat printed markers and stubby hands read as budget from across a table.
Caseback and finishing
Engraving should be sharp and evenly spaced, not laser-fuzzy. Brushed surfaces should run in one direction, with polished flanks that meet at a defined line.
Parameter bands to check
- Case diameter: 40 to 42.5 mm, with 39 mm on smaller references
- Case thickness: 13 to 14 mm on an automatic
- Lug width: 20 mm on the 42 mm case
- Subdials: 12, 6 and 9, with 30 minutes at the top
- Date aperture: at 3, framed, matching dial color
- Crystal: sapphire, slightly domed, flush or just proud of the bezel
- Water resistance marking: 3 bar, stated on the caseback
Common pitfalls
- Quartz versions sold as automatic. A ticking chronograph second hand gives it away in one second.
- Stock movements in oversized cases, which produce a thick watch and a wobbly crown.
- Photo sets that hide the caseback or the crown side.
- Sellers who will not show a reset-to-zero video. That single clip exposes most defects.
- Dial photos taken under heavy glare, which hides printing flaws and marker edges.
FAQ
Is a quartz Portofino replica worth buying?
Only as a costume piece. It will not feel like the watch it copies, and the chronograph action will not resemble a mechanical column or cam system.
Should the running seconds hand be at 9?
On a 7750-based Portofino Chronograph, yes. Center running seconds on a three-counter dial signals a different movement.
How can I check thickness without calipers?
Ask for a side profile photo next to a coin or a ruler. A case that looks tall relative to its diameter is usually over 14 mm.
Does the date font matter?
It is one of the fastest checks. Thin, tall numerals with tight spacing are correct. Wide, bold numerals with uneven gaps are not.
