The Audemars Piguet Royal Oak 16202 is the 2022 successor to the 15202 "Jumbo" Extra-Thin: the 39 mm steel case, 8.1 mm thickness, 50 m water resistance and date at 3 o'clock carry over, while the movement changes from the calibre 2121 to the calibre 7121, which beats faster, runs longer on a full wind and lets you set the date directly with the crown. Choose the 15202 if you want the original-generation calibre 2121 in a discontinued reference; choose the 16202 if you want the current movement and the newest production. This guide sets both side by side and explains how to source either. Bizak & Co. is a sourcing desk, so every watch here is found to order, not held in stock.

What is the difference between the Royal Oak 15202 and 16202?
The visible differences are small; the biggest changes are inside the case. The 16202 was introduced in 2022, the Royal Oak's 50th anniversary year, and replaced the 15202, which had been the Extra-Thin Royal Oak since 2000. Both keep the octagonal bezel with eight hexagonal screws, the integrated bracelet and the "Petite Tapisserie" dial pattern first used on the 1972 Royal Oak 5402. What changed is the calibre, including how the date is set, and the way the watch is made today.

Is the 16202 thicker or bigger than the 15202?
No: the two share the same 39 mm diameter and roughly 8.1 mm thickness, so they wear almost identically. That is the main reason the 16202 is seen as an evolution rather than a redesign. The "Jumbo" name comes from the 1972 original, which at 39 mm was large for a dress-leaning steel watch, and both references keep that proportion. If you have tried one on, you already know how the other sits on the wrist.
What changed inside: calibre 2121 vs calibre 7121?
The 16202 replaces the ultra-thin calibre 2121 with the newer calibre 7121, which beats faster and stores more power. The 2121 is a slim automatic that has powered the Extra-Thin Royal Oak for decades, running at 2.75 Hz with around 40 hours in reserve. The 7121 runs at 4 Hz, the same beat rate as Audemars Piguet's other modern Royal Oak movements, and lifts the reserve to about 52 hours, so the watch holds its time over a weekend off the wrist. The 7121 was built to fit the same slim case, which is why the thickness did not change.
Does the 16202 have a date?
Yes, and so does the 15202: both show the date in a window at 3 o'clock, as the original 1972 Royal Oak 5402 did. The difference is how you set it. The 15202's calibre 2121 has no quickset date, so you move the hands from 9 pm to just past midnight to advance it one day at a time. The 16202's calibre 7121 lets you pull the crown out to its first position and turn it to change the date directly.
Is the 15202 discontinued, and which is easier to find?
The 15202 is discontinued, so every 15202 you can buy today is pre-owned or an old unworn example, while the 16202 is the current production reference. The 16202 is sold through Audemars Piguet boutiques and authorised retailers, where allocation and waiting lists are common for steel Royal Oaks. Bizak & Co. sources either one to order from the secondary market, confirming the exact watch, photographs and price before you commit. Because we do not hold stock, availability and price depend on the specific unit we locate.
Which should you buy, the 15202 or the 16202?
Buy the 16202 for the newer movement, the quickset date and current production; buy the 15202 for the original-generation calibre 2121 and a finished, discontinued reference. Use this shortcut:
- Choose the 16202 if you want the 4 Hz calibre 7121, the longer power reserve and a date you can set directly with the crown, or a recent watch that may still carry its manufacturer warranty.
- Choose the 15202 if you want the original-generation Jumbo with the calibre 2121 that traces back to the 1972 5402, and a reference that is no longer made.
- Ignore the case size as a deciding factor, since both are 39 mm and about 8.1 mm thick.
Whichever you pick, dial colour, condition, an unpolished case and the full set matter more than the reference suffix. Browse the Royal Oak 39 mm collection to see the sizes and configurations we can seek, the broader Audemars Piguet Royal Oak watches, or the current Royal Oak models. If the 41 mm size suits you better, see the Royal Oak 41 mm collection. Use the from-prices on the linked listings as a starting point, because they move and a sourced unit may price differently. For the brand as a whole, visit the Audemars Piguet collection.
What should you check before buying a Jumbo?
Verify the full reference, the warranty card serial against the caseback, the bezel screws, the bevels and the bracelet. A polished case with rounded bevels is the most common compromise on a pre-owned Royal Oak, and the thin Jumbo case has little metal to spare. Ask for photographs of the caseback and the dial close up so the details match the stated year and reference. Our Royal Oak 15500ST vs 15510ST guide covers the same generation change in the 41 mm size.
Quick answers
What is the difference between the Royal Oak 15202 and 16202?
Both are 39 mm, 8.1 mm thick steel Extra-Thin Royal Oaks with the date at 3 o'clock. The 2022 16202 uses the calibre 7121 (4 Hz, about 52 hours) instead of the calibre 2121 (2.75 Hz, about 40 hours), and its date can be set directly with the crown.
Is the 16202 the same size as the 15202?
Yes. Both have a 39 mm case about 8.1 mm thick and 50 m water resistance, so they wear almost identically.
Is the Royal Oak 15202 discontinued?
Yes. Audemars Piguet replaced it with the 16202 in 2022, so 15202 examples are now sourced pre-owned or as old unworn pieces.
Which movement does the 16202 use?
The in-house calibre 7121, a selfwinding movement running at 4 Hz with about 52 hours of power reserve, replacing the calibre 2121 of the 15202.
Does Bizak & Co. keep the 15202 or 16202 in stock?
No. Bizak & Co. sources each watch to order, confirming the exact unit, photographs and final price with you before you commit.
