Audemars Piguet 16402: The Short Answer
Reference 16402 is not part of the Royal Oak numbering that Audemars Piguet publishes. The public Royal Oak catalog covers 5402, 14790, 15202, 15400, 15500, 16202, 26331 and 26400. A 16402 sits outside that sequence. Numbers like this come from reseller posts, forum threads and replica sellers. Treat it as a listing label until a caseback photo shows an engraving that matches a documented model.

How AP Reference Numbers Work
AP builds a reference from three blocks: model code, case material code, and dial or bracelet code. A full number reads like 15500ST.OO.1220ST.01. ST is stainless steel. OR is rose gold. TI is titanium. CE is ceramic. The five digits before the first period name the model. Most listings drop the suffix, so one model number can cover several watches with different metals and dials.
Why 16402 Shows Up in Listings
Three things produce numbers that look like AP references but are not. Sellers copy caseback engravings by hand and mistype digits. Factories issue internal codes and some sellers pass them off as AP numbers. Generations of the Royal Oak Offshore get mixed together, so a 42mm case gets paired with a number from a 44mm model.
why choose fake audemars piguet 16402
When a listing shows a 16402 with a Royal Oak or Royal Oak Offshore photo, match the case diameter, the movement and the engraving against a documented reference that carries the same specs.

Royal Oak Numbers to Compare
- 5402: first Royal Oak, 1972, 39mm, caliber 2121.
- 14790: mid-size Royal Oak, 36mm.
- 15202: Jumbo, 39mm, caliber 2121.
- 15400 and 15500: 41mm Royal Oak, caliber 3120 then 4302.
- 16202: Jumbo 50th anniversary, 39mm, caliber 7121.

- 26400: Royal Oak Offshore, 44mm.
What to Verify in a Listing
Ask for five items: case diameter in mm, a caseback photo with the engraving, the movement name and beat rate, water resistance, and weight in grams. A 42mm Offshore in steel on a bracelet sits near 180 to 200 grams. A 39mm Jumbo in steel sits near 110 to 120 grams. A number that does not fit the size on the page is a copy.
Check the beat rate against the movement claim. An ETA 2824 or a 7750 chronograph runs at 28,800 vibrations per hour. A listing that says Swiss automatic and shows 21,600 vibrations per hour has a mismatch.
Price Range
Replica Royal Oak listings run from about $120 for quartz models to $600 and up for versions with a cloned 3120 or 4302 movement. Genuine Royal Oak Jumbos trade at auction between roughly $40,000 and $200,000 based on reference, metal and condition. A 16402 listing priced near genuine market value is a warning sign.
Bottom Line
No AP reference 16402 appears in public catalogs. Use the number as a starting point, then match case size, movement and caseback engraving to a real reference. If a seller will not send a caseback photo, walk away.
