A fake Portofino watch listed as IW938 is a replica of the IWC Portofino line sold under a seller's internal stock code, not an official IWC reference. IWC reference numbers for the Portofino family follow patterns such as IW3565 or IW3910, and no IW938 reference exists in the brand's catalog. Treat IW938 as a listing label, then match the photos, dimensions, and movement description to the specific Portofino model the seller is copying.
What Does the "IW938" Code Actually Mean?
Replica sellers often invent short alphanumeric codes to track batches and factories. These codes change when a supplier updates a case, dial, or movement, so two listings with the same IW938 code can ship different watches. Before ordering, ask the seller which factory batch the code refers to and request photos of the actual unit, not catalog renders.

Which Portofino Model Is Being Copied?
Most replicas labeled this way target the Portofino Automatic 40mm, a three-hand dress watch with a clean dial and a thin case. Some listings copy the Portofino Chronograph, which has two sub-dials and pushers, or the smaller 37mm automatic aimed at narrower wrists. Confirm the case diameter, lug width, and dial layout in the listing, because the name Portofino alone covers several very different watches.
Portofino Watch IW938 Replica: A Comprehensive Guide
Case size and thickness
The genuine 40mm automatic measures roughly 9.5mm thick. A replica that looks bulky in profile usually carries a thicker movement spacer, which is the clearest tell in person.
Dial details
Look for applied indices that sit level, a printed logo with sharp edges, and sub-dials or date windows that align with the genuine layout. Flat printed markers and a smeared logo indicate a budget tier.
Movement type
Better replicas use a Japanese automatic such as a Miyota 9015 or a Chinese automatic clone, both of which sweep smoothly. A quartz tick at one-second intervals signals the lowest tier and rarely matches the genuine case thickness.
What Should You Check Before Paying?
- Real photos of the exact unit, including the caseback engraving
- Stated case diameter, thickness, and lug width
- Movement name and whether it is automatic or quartz
- Crystal material, sapphire versus mineral glass
- Strap type and whether a spare strap is included
- Return policy and shipping method in writing
Is a Fake Portofino Legal to Buy and Resell?
Owning a replica is not the same as selling one. Passing a replica off as genuine, or reselling it as an IWC product, exposes the seller to trademark claims and, in the United States, to seizure by Customs and Border Protection at import. Keep the paperwork and never represent the watch as authentic in a resale listing.
Frequently Asked Questions
Is a fake Portofino watch waterproof?
Most replicas are rated for light splashes only. Gaskets and caseback seals vary by batch, so avoid swimming and have the case tested if water resistance matters to you.
Do replica Portofino watches hold resale value?
No. Replica watches lose most of their value on the secondary market, and resale as a genuine item is illegal. Buy one as a wearable, not as an investment.
What strap size fits the 40mm Portofino replica?
The 40mm case typically takes a 20mm strap, while the 37mm version uses an 18mm or 19mm strap. Measure the lug gap on the actual watch before ordering a replacement.
