A "replica Portofino Midsize 39" is a counterfeit copy of an IWC Portofino, sold under a seller-invented size label. IWC's own catalog lists the Portofino Automatic in set case sizes, and "Midsize 39" is not one of them. That mismatch is your first signal: the listing describes a product the seller controls, not a watch the manufacturer ever made. If you are reading listings to decide whether to buy, the honest answer is that the money is at risk and the watch is not the one in the picture.
What the listings actually are
Most offers under this term come from marketplaces, social accounts, and drop-ship pages. The photos are frequently borrowed from genuine watch listings, owner forums, or earlier fake batches. Case diameter, dial finish, and strap hardware change between batches from the same seller, so two buyers who pay the same price can receive two different watches. The reference number printed on the case back is often copied from a real Portofino, which makes it easy to check against the genuine record and find the fraud.
Why the risk is real
- No manufacturer warranty, service network, or parts supply exists for the watch you receive.
- Movements in this price band often fail within months and cannot be repaired economically.
- Counterfeit watches are seizable goods. Customs authorities can hold or destroy shipments, and trademark owners can pursue sellers.
- Payment methods favored by these sellers, such as wire transfer, gift cards, and crypto, remove your ability to dispute the charge.
How to check a Portofino before you pay
- Request a clear photo of the case back with the full reference number and serial.
- Look up that reference against the official IWC Portofino page and compare case size, dial layout, and crown shape.
- Ask for a short video of the seconds hand sweeping and the date changing at midnight.
- Run a reverse image search on the listing photos to see whether they appear on other sites under different sellers.
- Ask the seller in writing whether returns are accepted, in what window, and who pays return shipping.
- Confirm the payment method is reversible, and treat any request for wire, crypto, or gift cards as a stop sign.
Genuine ways to get the same look
The Portofino's dress-watch formula, meaning a slim case and Roman numerals, is widely available without legal or mechanical risk. Options include a pre-owned genuine Portofino Automatic from a dealer with papers, or new dress watches from Tissot, Longines, Seiko Presage, Orient, and Frederique Constant at a fraction of IWC pricing. A pre-owned genuine piece holds value and can be serviced, which no counterfeit can.
Bottom line
Treat any "replica Portofino Midsize 39" offer as an unknown product from an unknown seller. If the goal is the style, buy a genuine watch at a price you can afford. If the goal is the badge, the cost is a watch that cannot be repaired, resold, or legally shipped in many cases.
