The replica Portofino Automatic 46 is a 46 mm automatic dress watch built to mimic IWC's Portofino design language. Good examples pair a 316L stainless case with a Swiss Sellita SW200-1 or a Miyota 9015, sapphire crystal, and a leather strap, while budget versions use a DG2813 and mineral glass. Because no genuine IWC Portofino Automatic is sold at 46 mm, the size label comes from the replica market rather than from Schaffhausen.
What does the 46 in Portofino Automatic 46 mean?
IWC catalogs the Portofino Automatic at 37 mm and 40 mm, and the larger 45 mm Portofino references are hand-wound rather than automatic. A 46 listing is therefore a replica-market naming convention that describes the case diameter the factory chose, not a real reference number. Ask the seller for a caliper photo before paying, because a listed 46 mm often ships at 43 or 44 mm.
Which movement should you look for?
Swiss clone: Sellita SW200-1 or ETA 2824
These run at 28,800 vibrations per hour with roughly 38 hours of power reserve and a smooth sweep. Expect hacking, hand-winding, and a date quickset that works in both directions on most examples.
Japanese: Miyota 9015
The 9015 offers 24 jewels, 28,800 vph, and about 42 hours of reserve. It is thinner than most Chinese options, which helps keep a 46 mm case close to 12 mm thick.
Chinese: DG2813 and its clones
These beat at 21,600 vph, which gives a slightly choppier seconds hand, and they often have a louder rotor. They are cheap to replace but rarely regulate to better than plus or minus 20 seconds a day.
Case, dial, and finishing checks
- Case diameter: measure across the bezel without the crown, where 46 mm should read 45.8 to 46.2 mm.
- Lug width: 22 mm on most 46 mm Portofino-style cases, so a 20 mm strap means the case is wrong.
- Crystal: sapphire with inner anti-reflective coating, since mineral glass scratches and hazes within months.
- Dial: applied indices, sharp printing on the minute track, and a date window aligned with the 3 o'clock marker.
- Caseback: engraved rather than ink-printed, with reference text legible under a loupe.
How much should a replica Portofino Automatic 46 cost?
Budget tier runs under $100 and uses mineral glass with a DG2813. Mid tier sits around $150 to $250 with a Miyota 9015, sapphire, and decent brushing on the lugs. Top tier reaches $300 and up with a Swiss Sellita, AR-coated sapphire, and a genuine-style calf or alligator strap.
Size and wrist fit
A 46 mm case with a 22 mm lug width sits like a small dinner plate on wrists under 7 inches. If your wrist measures 6.5 to 7 inches, a 40 mm or 42 mm Portofino-style case will look closer to the genuine proportions.
Legal and practical notes
Replica watches are counterfeit goods in the United States and most other countries. Customs can seize shipments, and no replica holds resale value, so treat any purchase as a disposable expense rather than an investment.
FAQ
Is a 46 mm replica too big for a 7 inch wrist?
Usually yes. A 46 mm case typically overhangs the wrist bone on a 7 inch wrist, and the lugs extend past the edges. A 40 mm to 42 mm case reads as a dress watch, while 46 mm reads as a statement piece.
Does the replica Portofino Automatic 46 keep accurate time?
With a Sellita SW200-1 or Miyota 9015, expect minus 10 to plus 20 seconds a day out of the box, and better after regulation. DG2813 examples often drift 20 to 40 seconds a day.
What is the biggest red flag in a listing?
A seller who cannot show a caliper measurement, a movement photo, or a caseback shot is hiding a smaller case or a low-grade movement. Always request live photos with a timestamp.
