Why the Audemars Piguet Perpetual Calendar 3399 Replica Is Cheap
A cheap 3399 replica is not a bargain version of a perpetual calendar. It is a different watch built to a lower cost target. The savings come from four places: a base movement with a bolt-on calendar module, a printed moonphase disc, a case with shallow finishing, and a bracelet with hollow links. None of those faults are hidden. You can spot them with photos and a short video before you pay. Use the price as a starting point, then verify the parts. If the seller cannot show the movement and the case thickness, walk away.

Prerequisites
- Measure your wrist and set a maximum case thickness you will wear daily.
- Decide if the moonphase must work or if a decorative disc is acceptable.
- Set a budget range and keep a repair reserve.
How to Evaluate a Cheap 3399 Replica
- Ask the seller to write the movement name and factory in the chat.
- Request a caseback photo with the rotor visible.
- Request a side photo with a ruler touching the caseback and crystal.
- Ask for a 20 second video that shows the crown being pulled and the pushers pressed.
- Confirm the subdials advance by asking for a date change from 28 to 1.
- Check the bracelet spec: solid mid-links, screw pins, and a machined clasp.
- Pay with a card or a platform that covers a return if the watch arrives off-spec.
Parameters That Explain the Price
Movement: The cheapest 3399 replicas use a 2813 or a 7750 base with a calendar module. A true perpetual calendar movement has a complex program wheel and hundreds of parts; a cheap module often has a printed or sticker leap-year indicator. Ask for a clone 5134 or a modified 7750 with a metal module if you want the calendar to work for more than a season.
Setting the Moonphase on an Audemars Piguet 3399 Perpetual Calendar Clone
Case thickness: A genuine Royal Oak Perpetual Calendar sits near 9.5 mm. Cheap replicas often reach 12 mm or more because the module stacks on top of the base movement. A thick case changes the wrist presence and the bracelet fit.

Dial and moonphase: Cheap dials use pad-printed subdials with soft edges and a flat moon disc. Better units use applied markers, a domed moonphase disc, and correct subdial spacing. Look for a crisp AP logo and a date wheel that sits flush.

Case and bracelet finishing: Cheap cases have polished bevels that are rounded, not sharp. The bracelet uses hollow mid-links and a stamped clasp. A better replica has solid links, a proper taper, and a clasp with crisp engraving.
Pitfalls to Avoid
- Buying from a listing that shows only front photos and no movement shot.
- Accepting a perpetual calendar label when the leap-year indicator never moves.
- Paying extra for a Swiss-made stamp on a Chinese module.
- Ignoring the return window on a calendar watch.
- Assuming a low price means a close copy; it usually means a different movement class.
Final advice: buy the specification, not the photo. A cheap 3399 replica can look correct on a wrist, but the calendar, thickness, and finishing are where the money went. Confirm those three items in writing, and the low price makes sense.
