Concluding Comment

The watch is the only modified version on the market that can deliver all these functions correctly. The case is German‑imported white ceramic developed from original data, with correct color (not milky/transparent), delicate brushing, polished chamfers, and clear AP engravings. The rotor is upgraded to 18K gold.
Strengths:
- Original genuine AP 2120 movement – reliable, authentic base, upgradable with perpetual calendar module.

Final verdict: The modified AP 26579CE white ceramic perpetual calendar is an exceptional build for serious collectors who want a fully functional perpetual calendar Royal Oak without paying the multi‑million‑yuan price of the genuine. The use of an original AP 2120 movement (with perpetual calendar module) ensures correct operation of all complications – including the rare quick‑adjust side buttons for month, week, and date. The German‑imported white ceramic case meets high standards of color and finishing. While still expensive, it is a fraction of the genuine’s cost. This is the ultimate AP perpetual calendar modification for those who demand both function and material authenticity. As always, independent verification of the movement (genuine 2120) and case quality is recommended. Bozwatch’s demonstration of the quick adjustments and the case details provides a solid checklist. This is the “spend less, achieve a full perpetual calendar AP” proposition at its peak.
Hello everyone, this is Bozwatch Reviews.
Every watch is a work of art, a testament to time, and I am a fanatic of them. I also hope that watch enthusiasts can avoid pitfalls and find their own mentor.
According to a fan’s request, they wanted to know whether the Audemars Piguet Royal Oak Perpetual Calendar watch can be modified and played with. Today, I paid out of my own pocket to buy this popular AP Royal Oak Offshore – the AP 26579CE white ceramic perpetual calendar.
For this watch, the case, the accessories, and the movement on the back are all completely unified. The movement is an original genuine 2120 movement that has been modified and upgraded. That means it uses a real original Audemars Piguet 2120 movement, and after modification and customization with a perpetual calendar module, it achieves all the functions of the 26579CE.
Here, I will focus on demonstrating how to use these functions and how to play with it.
The adjustment method of this watch is actually very interesting. When we turn the crown counterclockwise to unscrew it, then pull the crown out to adjust the time. When the time turns a full circle, the day and date will jump. See? It has already jumped.
- At 9 o’clock – day of the week sub‑dial
- At 3 o’clock – date sub‑dial
- At 6 o’clock – moon phase display
- At 12 o’clock – month sub‑dial
- The short hand and long hand are the hour and minute hands.
- The white needle is the week calendar hand – it indicates which week of the year you are in (52 weeks total). That’s all its functions.
So how do you quickly adjust it? Using the side buttons. For example, the upper left and upper right buttons. After we press them, you can see the month will jump. See? The lower right button – let’s press it. You can see the white week hand jumping. That’s its real week calendar function.
Let’s see what these side buttons do. Press one – the month moves. Press another – the week can be adjusted quickly. Press the top button – the date can be adjusted quickly. This is its adjustment function, completely consistent with the genuine. This is the only modified watch on the market that can achieve all the functions of the AP 26579CE white ceramic.
Now, the case of this watch is also exquisite. White ceramic cases on the market often have a milky white, somewhat transparent color – that’s incorrect. This case uses original data; we developed a German‑imported white ceramic case. Under light, whether it’s the brushing, the side chamfers, or the polishing – the finishing is excellent. Its color and texture are completely comparable to the genuine. That’s the craftsmanship a good product needs. See? Including the AP engravings – very clear.
As for the movement, as mentioned, it uses a genuine 2120 movement for modification. Its rotor has also been upgraded – an 18K gold automatic rotor. This movement can be sent to domestic professional testing institutions such as Yunyu, Xinhua, or Xu Butian for testing and re‑authentication.
In fact, the value of this modified watch is quite high. But compared to the original value of nearly 2 million yuan, it already helps you save money. The purpose of modifying a watch is to customize and upgrade it – to help you spend less money to achieve more.
This is the AP 26579CE white ceramic perpetual calendar – modified and upgraded with an original genuine movement, and equipped with a German‑imported white ceramic case.
