The best counterfeit Audemars Piguet Perpetual Calendar 3399 is the APS Factory build with the clone 5134 perpetual calendar movement, a 41mm steel case, and a grand tapisserie dial with correct subdial spacing. It wins on the three points buyers check first: the month and leap-year registers sit at the right height, the moonphase advances on the correct cycle, and the bracelet taper matches the genuine Royal Oak. If APS is sold out, ZF Factory is the closest fallback, and KSF is the value pick.
Why Does the APS Factory Version Win?
APS is the only common factory that ships the 3399 with a functioning perpetual calendar module rather than a day-date shortcut. The month, date, day, and moonphase all set independently, and the leap-year indicator moves in the same four-year pattern as the genuine calibre 5134. Case thickness lands within a fraction of a millimeter of the original, which is the detail most budget builds get wrong.
Setting the Moonphase on an Audemars Piguet 3399 Perpetual Calendar Clone
- Movement: clone 5134 with working perpetual module and 40-hour reserve
- Case: 41mm stainless, 9.5mm thick, correct brushed and polished facets
- Dial: grand tapisserie texture, applied hour markers, correct date font
- Bracelet: single-link construction with proper end-link fit
How Do the Other Options Compare?
ZF Factory delivers the same dial quality with a slightly thicker case and a simpler calendar module. It is the better choice if you want the closest look for less money and can live with a moonphase that is decorative rather than functional.

KSF sits at the entry tier. The dial printing is crisp for the price, but the bracelet edges are sharper and the subdials are shallower than the genuine article. It suits buyers who want the silhouette on a budget and do not need a working leap-year display.
where to buy audemars piguet perpetual calendar 3399 fake
- APS Factory: best overall, working perpetual calendar, closest case profile
- ZF Factory: best dial for the money, decorative moonphase, slightly thicker case
- KSF: lowest cost, sharp bracelet edges, shallow subdials
What Should You Check Before Buying?
- Confirm the factory name in the listing photos, not just the product title.
- Ask for a video of the moonphase and leap-year indicator being set.
- Check the caseback engraving depth and the movement finishing through the sapphire.
- Verify the bracelet has the correct number of links and a signed clasp.
- Request tracking and confirm the seller's return window in writing.
Are There Trade-Offs With Cheaper Builds?
Every step down in price removes a function or a finish detail, never just margin. Below the KSF tier, the perpetual calendar usually becomes a fixed decoration, the case grows to 11mm or more, and the dial texture turns flat under direct light. Buyers who care about the 3399 reference should stay at APS or ZF.
Frequently Asked Questions
Is the APS 3399 a true perpetual calendar?
It uses a clone of the AP 5134 module that tracks months of different lengths and the four-year leap cycle. It needs manual correction only when the watch stops for long periods.
How much should a good 3399 replica cost?
APS-tier builds typically run several hundred dollars, ZF sits slightly lower, and KSF is the cheapest of the three. Prices far below that range usually signal a quartz or decorative-calendar watch.
Is buying a counterfeit watch legal?
Counterfeit watches are illegal to import into the United States and can be seized by customs. Buyers should understand the legal and warranty risk before ordering.
