The replica Portofino Small Seconds 37 v2 is a second-version copy of the IWC Portofino Automatic 37. It is not an IWC product. The v2 label comes from a seller or maker. It has no official standard. Two sellers can use v2 for different watches.

What the v2 label means

Replica version labels track seller batches. A v1 to v2 change can cover dial print, subdial spacing, case finish, crown shape, or movement. No public parts list exists for a v2. Ask for photos of the dial, caseback, crown, and movement. Ask for the measured case diameter. The original IWC Portofino Automatic 37 uses a 37 mm case and a small seconds subdial at 6 o'clock. IWC lists those points on its site.

Check points for the Portofino Small Seconds 37 v2

  • Case: measure across the case without the crown. The target is 37 mm. A 39 mm or 40 mm case is a different model.
  • Dial: check the small seconds subdial at 6 o'clock. Check marker shape and print. Check the date aperture if the seller's photos show one.
  • Hands: check length. The minute hand should reach the minute track. The small seconds hand should sit in the subdial.
  • Caseback: check engraving depth and text. Compare fonts and spacing to photos of the IWC original.
  • Crown: check size and logo. A crown that sits proud or rubs the case is a fit issue.
  • Movement: ask for the calibre name, beat rate, and power reserve. A seller without these numbers gives you less to check.
  • Water resistance: do not trust a replica rating without a test. A 3 bar rating on the original does not transfer to a copy.

What v2 does not fix

A v2 label does not make a replica an IWC watch. It does not add IWC warranty, service, or parts support. Trademark law still applies. U.S. Customs can seize counterfeit watches. The Federation of the Swiss Watch Industry states that counterfeits infringe trademarks and sit outside maker service. Budget for a watchmaker inspection and a pressure test. Keep the seller's photos and the order record.

Questions to ask before you buy

  1. What is the measured case diameter and thickness?
  2. Which movement is in the watch, and what is its power reserve?
  3. Can you send a photo of the caseback and crown?
  4. Is the bracelet or strap width listed?
  5. What is the return window?

If the seller cannot answer these points, the v2 label has no use. The label is a batch name, not a spec sheet.
