If you are shopping for a first copy Portofino 45, the movement matters more than the case polish. The 45 mm Portofino is built around a hand-wound, eight-day movement, and a working power reserve indicator is the detail a copy is least likely to get right. Ask the seller to show the reserve subdial climbing over several days of winding. If that subdial never moves, the movement is decorative and the rest of the watch is a costume piece. Settle that question first, then judge the dial, the crystal, and the strap.
What the name refers to
"Portofino 45" points to the 45 mm Portofino family, led by the Hand-Wound Eight Days. That watch carries a manual-wind in-house calibre with a 192-hour power reserve, small seconds at 6 o'clock, a power reserve arc at 9 o'clock, and a date at 3 o'clock. Some perpetual calendar and tourbillon Portofino references share the same 45 mm case, so the name alone does not identify one watch. Before you compare anything, confirm the reference number the seller is copying and pull the official specification for that exact piece. A copy measured against the wrong reference will look correct to a seller and wrong to anyone who knows the watch.
What to look for
Case and proportions
Measure across the case at 3 and 9, excluding the crown. The nominal figure is 45 mm; copies often land between 45.5 and 46.5 mm, which changes how the watch sits. Thickness is the better tell. A hand-wound Portofino is a slim watch, and a copy that comes in under 10 mm has lost the dial depth that makes the layout readable, while one over 14 mm wears like a slab and will not sit under a cuff. Check lug width (22 mm on this case) and total lug-to-lug length, which pushes past 50 mm and makes the watch wear large even on a 7.5 inch wrist.
Movement type
Copies of this watch fall into four groups: quartz, base automatic with painted subdials, decorated automatic with working small seconds but a fake reserve, and a hand-wound build that reproduces the 8-day layout. Only the last group behaves like the original. The others still keep time, but the power reserve display is the giveaway. Ask what the reserve indicator does under winding, and ask for a short video rather than a still photo.
Dial, hands, and printing
Look for applied indices with polished edges and a flat top, not stamped foil. Text should be crisp at the edges, not fuzzy or doubled. The date window should be centered in its aperture with a font that matches the reference. Hands on this family are thin and long, and copies often ship short, thick hands that sit wrong against the minute track. Check that the small seconds hand sweeps without stutter.
Crystal, caseback, and strap
The original uses sapphire with anti-reflective coating applied to the underside, which keeps reflections low and avoids the blue haze seen on coated outside surfaces. Mineral glass scratches and shows a heavier tint. Caseback engraving should be deep and evenly spaced, not laser-etched and shallow. Straps vary by reference; alligator-grain leather with clean edge stitching is the baseline, and a thin, glossy strap is a sign the seller cut cost where buyers notice least.
Parameters worth verifying
- Case diameter: 45 mm nominal, measured at 3 and 9 o'clock
- Lug width: 22 mm
- Lug-to-lug: over 50 mm, so confirm it fits your wrist
- Case thickness: slim profile consistent with a hand-wound movement
- Power reserve: 192 hours on the original layout, with a live indicator
- Subdials: small seconds at 6, reserve arc at 9, date at 3
- Crystal: sapphire with underside coating
Pitfalls to avoid
- Stock photos pulled from the brand site instead of the actual unit
- "1:1" claims with no measurement photos or video
- Static subdials presented as functional complications
- Mineral glass described as sapphire
- Plated finishes that wear through at the case edges and crown
- Water resistance claims with no gasket detail or pressure test
- No return window, no inspection period, and no clear shipping terms
Before you pay
- Confirm the exact reference being copied and its official dimensions
- Request photos of the actual watch with a ruler, or in-hand video
- Ask what the reserve indicator does when wound
- Ask what the crystal material is, and how it was verified
- Ask about the return window, shipping method, and who covers a seized parcel
- Get the seller's answers in writing before sending money
Legal and practical risk in the US
Counterfeit watches are not a neutral purchase in the United States. Imported counterfeits are subject to seizure and destruction by Customs and Border Protection, and trafficking in counterfeit goods carries civil and criminal exposure under trademark law. Personal use is treated with more leniency than resale, but the parcel can still be lost, and there is no refund from a seller who ships into that risk. Servicing is a second problem: no authorized watchmaker will touch a counterfeit, and independent repair shops may refuse or struggle to source parts. If you resell, describe the watch accurately. Passing a copy off as the original is fraud, and it is the fastest way to turn a hobby purchase into a legal problem.
FAQ
How can I tell if the power reserve is real?
Wind the watch fully, then watch the reserve arc over two or three days. A real indicator advances and then retreats as the mainspring unwinds. A painted or geared-to-nothing subdial stays put.
Is a quartz copy worth considering?
Only if you want the look and do not care about the sweep of the small seconds. A ticking subdial is visible at arm's length and reads as a copy.
Does case diameter really vary that much?
Yes. Case finishing and bezel thickness shift the measured size, and two copies from different workshops can differ by more than a millimeter. Measure before you commit, especially if your wrist is under 7 inches.
What is the biggest single red flag?
A seller who cannot or will not send in-hand video of the exact unit you are buying. Everything else can be argued; that one cannot.
Will a copy hold value?
No. First copy watches are consumer goods, not collectibles. Treat the money as spent, and factor in that servicing may be hard or impossible.
