A fake Patek Philippe perpetual calendar 5320G is a replica of the 40 mm white gold perpetual calendar that Patek Philippe launched in 2017. Replicas reproduce the cream lacquer dial layout and the case silhouette at a fraction of the price, but they do not carry the genuine Calibre 324 S Q, the solid gold case, or the hand finishing, and importing or selling them as genuine watches is illegal in the United States and most of Europe.
What the Genuine 5320G Actually Is
Knowing the real watch makes the fake Patek Philippe perpetual calendar 5320G easier to judge. The reference was introduced as a vintage-inspired perpetual calendar with a warm cream dial, a look Patek Philippe had not used in decades.
- Case: 18k white gold, 40 mm, sapphire crystal front and back.
- Dial: cream lacquer with applied gold numerals and printed scales for day, date, month, and leap year.
- Functions: perpetual calendar plus moonphase and a day/night indicator.
- Movement: Calibre 324 S Q, self-winding, with roughly 38 to 45 hours of power reserve.
- Certification: the Patek Philippe Seal, which covers rate accuracy and finishing standards.
The genuine perpetual calendar mechanism accounts for leap years automatically and needs no correction until 2100, apart from winding and time setting.
How Replicas of the 5320G Differ
- Movement: Most replicas use a generic automatic base with a calendar module bolted on. The leap year function is often decorative, and the calendar may need manual correction at the end of short months.
- Case metal: The original is solid white gold. Copies are usually steel with rhodium plating, so the watch feels lighter in the hand and wears differently over time.
- Dial printing: Genuine dial text and scales are razor sharp under magnification. Replica printing tends to look slightly thick, uneven, or misaligned at the subdials.
- Moonphase: A real moonphase tracks a 29.5 day lunar cycle. Many replicas use a 24 hour disc that simply spins once a day.
- Finishing: Look through the sapphire back. Bridges, bevels, and screws on the real movement are finished by hand and show crisp angles rather than uniform machine brushing.
Spotting a Fake 5320G: A Practical Checklist
- Weigh the watch. Gold has a density steel cannot imitate, and the real 5320G has noticeable heft for its size.
- Examine the subdial edges and the leap year aperture under a loupe for rough cutting or sloppy paint.
- Check the crown for a clean, centered engraving and smooth winding action.
- Inspect the caseback for gold hallmarks that are stamped rather than laser etched.
- Compare the serial and reference numbers on the case with the paperwork supplied.
- Ask for the movement view. A decorative rotor with printed lettering is a clear sign of a copy.
Legal and Practical Risks
Counterfeit watches are treated as infringing goods. In the US, customs officers can seize shipments, and trademark law allows both criminal charges and civil claims against sellers. Auction houses, marketplaces, and payment processors routinely remove listings and freeze accounts tied to counterfeits.
The practical downside matters just as much. A replica has no manufacturer service path, no warranty, and no resale value. Claims of Swiss movement or water resistance on a replica are usually unverifiable, and a seller describing a copy as a genuine Patek Philippe is committing fraud.
Questions to Ask Before You Buy
- Is the watch described honestly as a replica, or is it being passed off as genuine?
- Can the seller show an in-focus photo of the movement through the caseback?
- Does the price sit anywhere near the range that genuine 5320G examples trade at on the secondary market? A very low price is the loudest signal of all.
- What happens if the watch arrives broken? Replicas rarely come with any return terms worth relying on.
Treat any 5320G offered far below market value as a copy until proven otherwise, and treat the replica itself as a novelty rather than an investment.
