Short answer
If you are asking whether a Portofino Chrono is fake, I start with four places: the subdial layout, the date window, the crown and pushers, and the movement under the caseback. The IWC Portofino Chronograph has a specific two-register design, a 30-minute counter at 12 and small seconds at 6, with the date at 3. Fakes often get the spacing wrong, use a generic date wheel with the wrong font, or hide a basic 7750 clone behind an engraved rotor.
Fake Portofino Chrono Watch Guide: How to Spot the Fakes
Subdials and date window
On a real Portofino Chrono, the subdials sit at 12 and 6. The gap between them and the center hands should look balanced. Many fakes push the subdials too close to the center or too far out. The date window is another tell. Genuine IWC date fonts are clean and thin. Replicas often use a thicker, rounder font that looks like it came from a parts bin.
fake portofino chrono question
- Subdial hands should be flat and polished, not painted.
- The date should snap over at midnight, not drift.
- Print on the dial should be crisp under a loupe.
Caseback and movement
Flip the watch over. Genuine Portofino Chronographs from the last decade use the 79320 calibre, which is based on the ETA 7750. Newer 39mm models use the in-house 69355. A fake may use an unmodified 7750 clone with no perlage, no Geneva stripes, and a rotor engraving that looks stamped rather than cut. The Probus Scafusia text on the rotor should be sharp. If it looks fuzzy or shallow, that is a problem.

Crown, pushers, and crystal
The crown on a real Portofino Chrono has the IWC logo in relief, and it turns smoothly. Pushers should have a firm click with no mush. The sapphire crystal should have an anti-reflective coating that makes the dial almost disappear at an angle. Cheap fakes skip the coating or use mineral glass that reflects like a mirror.

What first copy means in this conversation
A first copy watch is a high-end replica built to look like the original. It is not the same as a cheap $40 fake. First copies often use a real 7750 movement, sapphire crystal, and a case that matches the dimensions. The question people ask is whether a first copy can pass as real. The honest answer: it can pass at arm's length, but a jeweler or a watchmaker who opens the caseback will know. If you are buying a used Portofino Chrono, assume any deal that seems too good is a first copy or worse.
Quick checklist
- Subdial spacing: 12 and 6, balanced.
- Date font: thin and clean, not bold.
- Crown logo: crisp relief, not a sticker.
- Rotor engraving: deep and sharp, not stamped.
- Crystal: AR coating, not mirror-like.
- Weight: steel case should feel solid, not hollow.
If you are still unsure, take it to a watchmaker. They can open the caseback in two minutes and tell you what movement is inside. That is the only answer that matters.
