Concluding Comment
This video covers the latest upgraded version of the Audemars Piguet 15500ST blue dial steel mesh. The improvements over previous versions include: a case redeveloped with original data (delicate brushing, polished chamfers, and a gradually thinning strap – top thicker, bottom narrower); high‑quality aftermarket dial, hands, and date wheel (correct sunburst, tapisserie spacing, 3D hands with upgraded central axis, thick date); and a significantly upgraded clone 4302 movement – now featuring a free‑sprung balance with counterweights (previously only in genuine watches), engraved (not printed) gilded bridges, and a real 18K gold rotor (replacing copper).

Strengths of this upgraded version:
- Correct case finishing and strap taper – addresses a common flaw in previous versions.
- High‑quality dial, hands, date – tapisserie spacing, sunburst, 3D hands, thick date.

- Value proposition – offers a very convincing 15500ST replica with significant improvements over earlier versions.
Final verdict: The upgraded AP 15500ST blue dial is an excellent choice for collectors who want a Royal Oak with a highly accurate dial, improved case finishing (correct strap taper), and a movement that now features free‑sprung counterweights, engraved gilded bridges, and an 18K gold rotor – details that bring it much closer to the genuine. For those seeking a top‑tier 15500ST modification, this latest version represents a significant step forward. As always, independent verification of the movement and finishing is recommended. Bozwatch’s emphasis on the free‑sprung balance, engraved bridges, 18K rotor, and strap taper provides a solid quality checklist. This is the “latest and greatest” AP 15500ST modification.
Hello everyone, this is Bozwatch Reviews.
Every watch is a work of art, a testament to time. I am a fanatic believer in them, and I also hope that watch enthusiasts can avoid pitfalls on their journey and find their own “Bole” (discerning patron).
Today, I will share the latest upgraded version of the Audemars Piguet Royal Oak 15500ST blue dial steel mesh. Compared to previous versions, this watch is also made using CNC original data. It has been upgraded in every aspect – the case, the surface accessories, and the movement on the back – making it even more refined, so you will be more confident when wearing it.
So what has been modified on this watch?
First, the 15500ST is a steel watch. We redeveloped the case using original data. Whether it’s the brushing, the polished surfaces, or the chamfering and polishing – the finishing is very, very good. You can see it’s very delicate.
For an AP strap like this, there is an important detail: its strap is gradually thinning – the top section is thicker, and the bottom is narrower. After the upgrade, the strap has this tapered design. That’s the case.
Now, the surface accessories – dial, hands, and date wheel – are also developed with original data. These are aftermarket parts. What does “aftermarket accessories” mean? It means this dial is highly faithful to the genuine – the dial color, sunburst pattern, and the distance between the tapisserie squares – everything is fully restored. The quality is excellent.
Here, I also took some close‑up pictures. This is an enlarged photo of the dial. You can see the uniformity, the tapisserie spacing, the sunburst effect, and the color – all completely aligned.
For the hands, the central axis has been upgraded – it’s more obvious. The hands are three‑dimensional aftermarket hands with no burrs on the sides. See? That’s the craftsmanship a good hand should have. The date wheel is a thick‑fill aftermarket part that fills the entire date window. The front effect is very well done.
Now, what about the movement on the back? What areas have been upgraded?
First, the movement model is the 4302. Our movement is made by molding after the original genuine movement – customizing an integrated 4302 movement. It replicates the original 4302 in appearance, thickness, and all functions.
It has a true free‑sprung (non‑caliber) structure. The balance wheel has been upgraded with counterweights. Let me show you a magnified picture. This is the free‑sprung structure – there are counterweights around the balance wheel. This counterweight process only appears in original watches, but through modification, customization, and upgrading, we achieve a completely consistent movement structure.
The bridges have been re‑gilded and engraved. See? The engravings are actually engraved – on previous movements, the engravings were printed, which wasn’t correct. After the upgrade, the engravings are gilded.
The rotor is made of real 18K gold – an automatic rotor. On the market, most rotors are made of copper. First, the color is wrong – the original is 18K rose gold. Second, 18K gold is heavier than copper, so its winding efficiency is higher.
The new version of the molded 4302 movement is now very close to the original genuine 4302. That’s very, very good.
For this AP 15500ST steel mesh modification, the dial color comes in many options – blue, black, green, and grey – all can be made. It mainly depends on personal preference.
When choosing this kind of AP modification, you must carefully distinguish. Only after you understand it clearly can you enjoy it.
This is the latest upgraded version of the AP 15500ST – a modified watch.
