For most buyers, the replica Audemars Piguet complication that holds up best is a working chronograph on a modified 7750 base or a clone of the in-house chronograph layout: the pushers start, stop and reset, the subdials sit where the genuine ones do, and the watch stays near the original thickness. Five criteria separate a convincing build from a display piece: does the complication actually function, how is the movement constructed, do the subdials and date window land in the right places, how close is the case thickness and finishing, and how does the dial read from a normal viewing distance.
How to judge a replica AP complication
- Function first. A chronograph that runs and resets is worth more than a calendar that only looks correct.
- Movement architecture. Look for a clone or a modified base whose layout matches the genuine calibre, not a generic movement with a decorated plate on top.
- Subdial and date placement. Compare against reference photos. Off-centre subdials and a misplaced date aperture are the fastest tells.
- Case profile. Royal Oak cases taper, bezel screws sit flush, and bracelet links flex in a specific way. Extra thickness of two or three millimetres shows under a cuff.
- Finishing. Bevels, brushing direction and the tapisserie grid should stay crisp at arm's length.
No replica is identical to the original. The practical question is which complication gives the most believable result for the money and the risk, and that answer changes with how you plan to wear the watch.
Chronograph (Royal Oak and Offshore)
The chronograph is the safest choice in this family. The movement is well understood, parts are common, and the pusher positions match the genuine case because the case itself is a copy of a chronograph case.
- Pros: the complication works; subdial spacing follows the original; replacement parts and servicing are easier than for a calendar or tourbillon; the widest range of dial colours and references.
- Cons: pusher feel is lighter and the reset snap is softer; date font and subdial ring printing vary between batches; Offshore versions run thicker than the original.
Use case: daily wear, office, and travel where the watch is seen at conversational distance.
Perpetual calendar
The three-subdial calendar layout is the most visually striking AP complication, and it is also the easiest to get wrong. Genuine perpetual calendars track leap years and weeks; many replicas reproduce the layout while those additional indications stay static or advance through a simplified module.
- Pros: the dial reads as a genuine high complication at a glance; moonphase, day and month apertures give strong presence; a good match to dress and collector settings.
- Cons: thickness is often well beyond the original; moonphase discs are usually printed rather than engraved; leap-year and week indicators may not move; date change timing is imprecise.
Use case: occasional wear and display, not a daily driver.
Tourbillon
A visible rotating cage is a real mechanical feature, which is why tourbillon builds attract attention. The cage rotates once per minute in most versions, and the open dial gives the movement nowhere to hide.
- Pros: the complication is genuinely mechanical and visible; open working suits skeleton dials; a strong conversation piece.
- Cons: cage finishing is coarse on many builds; rate stability and power reserve suffer; the cage adds height to the case; repair options are limited.
Use case: collectors who want a mechanical talking point and accept the trade in accuracy.
Openworked and skeleton dials
Skeleton work removes the safest part of any replica, namely the dial. What remains is bridge shape, anglage and screw finishing.
- Pros: no dial printing to misjudge; visually impressive; hides subdial alignment problems by removing subdials.
- Cons: bridge shapes may not follow the genuine calibre; fake jewels and painted perlage are visible through the crystal; screws and engraving are often oversized.
Use case: buyers who can compare bridge geometry against reference photography before ordering.
Dual time and GMT
Dual time is the least risky complication after the chronograph because the mechanism is simple and the dial layout is easy to copy.
- Pros: practical second time zone; few failure points; subdial and 24-hour ring placement are straightforward to replicate.
- Cons: the second zone is often set through the crown rather than a dedicated pusher; 24-hour ring printing can be thin or misaligned; power reserve indicators on some references are decorative.
Use case: frequent travellers who want the AP look with useful function.
Minute repeater and grand complications
Repeater replicas exist but the chime is the weak point. A true minute repeater strikes hours, quarters and minutes on demand through racks and snails; replica versions rarely follow that sequence correctly, and sound quality depends on case material and gong placement.
- Pros: rare in the replica market; a genuine statement piece; complex case and dial work.
- Cons: chime accuracy is unreliable; case thickness grows to fit the module; service is close to impossible; supply is thin.
Use case: experienced buyers who value rarity over function.
Which one to pick
- One watch, worn often: chronograph. Best function, best proportions, easiest repair.
- Dress and display: perpetual calendar, if you accept the thickness and static indicators.
- Mechanical showpiece: tourbillon or openworked, chosen after comparing bridge shapes.
- Travel: dual time, for the lowest risk of a broken complication.
What to check before you buy
Ask for a video of the complication running, not a still photo. Confirm case diameter and thickness against the reference you want. Check subdial spacing with a straight-on dial shot. Ask which movement base is used and whether it is a clone or a modified third-party calibre. Confirm the bracelet end links sit flush against the case, and that the bezel screws align in the correct direction. Finally, decide in advance how you will handle service, because a complication replica with a stopped calendar or a jammed chronograph is a paperweight.
