The New Audemars Piguet Royal Oak Jumbo Extra-Thin 16202ST to Replace the 15202ST (Video & Live Pics)
The Jumbo is and remains the Jumbo, it's just getting better!
Kill your darlings is what they say, and around the same time last year, Patek Philippe killed the 5711, and Audemars Piguet killed the über-popular 15202. Within a few weeks, the two most popular watches on planet Earth were discontinued, generating a good deal of turbulence in the world of watches. AP’s Royal Oak Extra-Thin, a.k.a. ‘Jumbo’, is now being replaced by the new reference 16202. Has the Jumbo changed a lot? Well, yes and no. It’s equipped with a new movement, but more importantly, the 16202 still looks very much like a Royal Oak Jumbo. Let’s take a closer look at the all-new stainless steel Audemars Piguet Royal Oak Jumbo Extra-Thin 16202ST.
As said, it has changed a LOT.
For the first time since 1972, the Royal Oak Jumbo Extra-Thin will be equipped with a different movement, and that’s actually pretty big news! So far, the RO Jumbo has been equipped with the Jaeger-LeCoultre cal. 920 ébauche, which Audemars Piguet christened as calibre 2121 (for the version with date, while the version without date was named calibre 2120.) The other two brands of the “Holy Trinity”, Patek Philippe and Vacheron Constantin, also used this movement, although they baptised it with different calibre numbers. Audemars Piguet also used this movement in almost every (self-winding) perpetual calendar (except for the ref. 25800). It has been a great movement for the Royal Oak Jumbo for fifty years, reliable and sturdy enough despite its thinness, but it was time for something new.
And that “something new” comes in the shape of a new extra-thin movement. The new Royal Oak Jumbo Extra-Thin 16202ST is not equipped with just another movement. No, it now comes with a brand new, in-house developed and manufactured movement named calibre 7121. This calibre offers a longer power reserve, an increased frequency and comes with a quick-set date. And these are useful improvements!
Calibre 7121 vs. 2121
- power reserve increased from 40h -> 55h
- frequency increased from 19,800vph -> 28,800vph
- thickness from 3.05mm -> 3.2mm
- quick-set date
- rotor now mounted on ball bearings
- balance wheel with directly inserted inertia blocks
The increased power reserve is achieved by a longer mainspring, and that’s just really pleasant as the 40h autonomy when fully wound might have been a tad outdated these days. The 55h of power reserve that the new calibre delivers stretches the autonomy up to more than two days. It also allows AP to get a more stable rate for a more extended period, improving its chronometric performances.
At least as important is the increased frequency. Going from 19,800 vibrations/hour to a modern 4Hz (28,800 vibrations/hour) is another opportunity for AP’s watchmakers to regulate the watch to a higher precision. And the now available quick-set date is probably the best improvement altogether.
The new calibre 7121 is a bit larger and thicker than its predecessor, but this has no impact on the case size of the new Royal Oak ‘Jumbo’. The diameter is now 29.6mm (over 28.0mm for cal. 2121), and the thickness has increased to 3.2mm (versus 3.05mm for cal. 2121.) Another important improvement on the movement side is that the central rotor is mounted on ball bearings, producing less wear and tear. The balance wheel in the new movement is fitted with inertia blocks that have been directly inserted within the balance wheel to avoid unnecessary friction. And last but not least, the new movement is equipped with a patented extra-thin, low-energy date-setting mechanism.
And finally… the rotor will be adorned with a styled “50 years” logo. But this will only be featured on the watches manufactured this year! As of 2023, the rotor on all Royal Oaks will no longer feature that cool “50 years” logo!
The lineage in reference numbers
The reference number 16202ST seems like a logical successor to the previous RO Jumbo ref. 15202ST. However, the lineage of reference numbers for the Royal Oak Jumbo didn’t always evolve as logically as this time.
Originally introduced in 1972 as the reference 5402ST, it disappeared from the catalogue for some ten years until it was relaunched in 1992 with the references 14802ST (Jubilee edition for the 20th anniversary) and 15002ST (regular model). While the 14802ST added a see-through caseback and subsequently a slightly thicker case, the reference 15002ST remained pretty close to the original design and proportions of the ref. 5402ST.
Eight years later, in 2000, AP introduced the reference 15202, which would replace the other previous references. Like the former reference, this watch featured a see-through caseback, but its dial featured the so-called Grande Tapisserie or big ‘cobble stone’ pattern (or Clous de Paris as it’s called in French.) In 2012, the 15202 was refreshed, mainly bringing back the smaller Petite Tapisserie pattern like the one found on the original 5402ST.
One factor, which might seem like a small thing, but it certainly isn’t a small thing to collectors (!!), is the position of the AP logo. On the original 5402ST, the AP logo was positioned between the dial’s centre and the 6 o’clock marker. This was the case for the A-series, B-series, and maybe some of the C-series; however, exactly how & when is not very clear… Let’s say that towards the end of the 1970s, around the C-series and D-series production, the AP logo was transferred to the 12 o’clock position. As for the revamped 15202ST that was introduced in 2012, the AP logo was back at the 6 o’clock position again. And for the 16202ST, the AP logo remains at the 6 o’clock position. This, plus the lack of a seconds hand, make it easy to identify the Royal Oak Jumbo Extra-Thin from other Royal Oak models.
As said, it hasn’t changed much at all…
The most important news about the new 16202ST is that it still looks very much like the 5402ST, the 14802ST, the 15002ST and the 15202ST… and that’s a good thing! While the engine inside changed, for the better, the looks and proportions of the watch remain pretty much identical. The diameter still measures 39mm, and its thickness is still 8.1mm. The bracelet remains the same and is still hand-finished with satin-brushing and polished chamfers. The bracelet is closed with a double folding clasp, identical to reference 15202ST. In short, it’s almost entirely the same as the previous generation, at least for the external parts.
Other factors that did not change are the dial, the markers and the hands. The dial colour remains the same blue, which Audemars Piguet calls Bleu Nuit, Nuage 50 – which, translated to English, is “night blue, cloud 50”. Also, the hour markers, the minuterie (minute markers), the applied AP logo, the “Audemars Piguet automatic” printing and the date window are all the same. Although it is almost impossible to see, the date window has been moved a fraction of a millimetre towards the edge of the dial.
At a later moment, we’ll put the 5402ST, the 15202ST and the 16202ST next to one another.

And here’s a selection of photos, and of course, don’t miss the video review at the top of the article!
Wow, 4Hz, 50 Meter WR, 55 Hours PR, no micro adjustment, all for just € 32.400. Is this a joke!!! AP RO is highly overrated.
Where to buy 16202 The New Royal Oak Jumbo 16202ST?
At the AP boutique
Random fact. I had a 37mm RO, bought unworn in 2017. The case and bracelet finish were nice, as was the dial. The movement also looked good enough through a loupe, and had a fancy rotor…
However, it was very poorly regulated so chronometric performance was a joke, and the minute hand moved more than a whole minute when pushing the crown in after adjusting the time. Not the first watch I’ve seen the hand move, for sure, but this was moving 3 times more than the next worse one. Took a lot of patience to set it correctly.
When I thought I could use an extra link, the boutique quoted 650 EUR…
Traded it towards a PP 3940 less than a year later. Don’t think I’ll ever want to touch another current production AP anytime soon.
