Here are the essential features of this top‑tier modified AP Royal Oak chronograph:
1. Model & Unique Feature
- Model: Audemars Piguet 26240 BA
- Known as Frosted “Two‑Gold” or Florence hammering process – the case and strap have a hammered texture with tiny particles that sparkle under light
- This texture is hand‑hammered by master craftsmen – not machine‑made
2. Material & Weight
- Case, strap, and buckle are made from real precious metal AU750 18K gold
- Total weight: 248 grams – exactly matches the genuine
- Only real precious metal can achieve this weight
- Described as a “half‑kilogram gold watch” (approx. 0.55 lb)
3. Case & Bracelet Craftsmanship
| Aspect | Details |
|---|---|
| Thickness | Matches genuine exactly |
| Finishing | Polished surfaces, chamfering, and polishing all consistent with original |
| Critical detail – strap taper | Upper part of strap is thicker, bottom part is thinner – a gradual thinning process. Many factories make strap links uniform (incorrect). This gradual thinning is a key identifier of a correct version. |
| Hammering texture | Hand‑hammered by master, not machine – creates sparkling effect under light |
4. Dial & Hands (Top‑tier Aftermarket)
- Dial, hands, calendar – all customized based on original data
- Dial golden color matched to genuine; radial lines are very full under light
- Three‑eye chronograph sub‑dials – sparkle effect matches genuine
- Hands are three‑dimensional
- Calendar is a thick calendar – fills the entire calendar window (not shallow)
5. Movement
- Equipped with a moulded / clone 4401 integrated movement (based on genuine AP calibre 4401)
- Fully functional flyback chronograph (non‑reverse timing function)
- Functions:
- 6 o’clock – running seconds hand
- 9 o’clock – chronograph minute counter
- 3 o’clock – chronograph hour counter
- Large centre hand – chronograph seconds hand
- Movement thickness, structure, and human position all match genuine
- Achieves true flyback chronograph functionality (not a decorative fake)
6. Overall Restoration Philosophy
- Modification aims for comprehensive restoration in all aspects:
- Case texture
- Material (18K gold)
- Weight (248g)
- Surface accessories (dial, hands, calendar)
- Movement structure and function
- Claim: When worn, as long as not sent to a professional testing agency, no flaws will be noticeable
- The buyer is essentially paying for the gold – transformed into an 18K gold watch that looks like a million‑yuan AP

Audemars Piguet Royal Oak chronograph 26240 BA with the iconic “Florence hammering” (two‑gold) finish. Unlike the previous AP 15500 (steel), this is a full 18K gold build weighing 248 grams – matching the genuine exactly. The hammered texture is a signature AP Royal Oak precious‑metal design, and the video emphasizes that this is hand‑hammered by masters, not mass‑produced by machine – a critical distinction for authenticity.
This modified AP 26240 BA “Two‑Gold” represents the peak of precious‑metal AP replicas – combining real 18K gold, hand‑hammered texture, correct strap taper, and a functional flyback chronograph movement. The weight (248g) alone tells you this is not a cheap plated watch. For collectors who appreciate AP’s hammered gold Royal Oak but cannot afford the genuine (which can cost well over 1 million yuan in the secondary market), this custom build offers a compelling alternative with significant intrinsic gold value.
Bozhong’s emphasis on the gradual thinning of the strap and hand‑hammering vs. machine‑hammering provides two very useful, often‑overlooked quality checks. The use of a clone 4401 movement with working flyback is also noteworthy – many factories only offer decorative chronographs. As with all such builds, transparency is key: the buyer is paying for real gold and skilled craftsmanship, but the watch remains an unauthorized replica with a clone movement and aftermarket dial. For the informed collector who accepts these terms, this is arguably the most impressive modified watch reviewed across all eight videos – not because it’s the most expensive, but because it successfully replicates one of AP’s most distinctive and difficult‑to‑make finishes (hammered gold) with genuine weight, material, and functional movement.
Hello everyone, this is Bozwatch Watch Talk.
Every watch is a work of art, a testament to time, and I am a fanatic believer in them. I also hope that all watch enthusiasts can avoid pitfalls and find their own “Bole” (a discerning patron).
Later, fans sent me private messages wanting to know about the current market’s best modified and upgraded watch – the 26240 BA Two-Gold. They asked me to make a video with them to authenticate it. Well, today it’s here.
For the 26240 BA Two-Gold, it is made of 18K gold. If we want to play with the same material and achieve the same weight, we need to use real precious metal – AU750 18K gold – to make its case and strap.
A watch modification like this is achieved through two aspects. The first is the case and the gold case craftsmanship of the strap. The second is the surface accessories and the craftsmanship of the movement inside. Through original data development, we can achieve a comprehensive restoration in terms of the case, strap material, weight, the color and texture of the dial and accessories, and the style and function of the movement.
With modification and customization like this, you can wear it without embarrassment – it doesn’t look fake at first glance.
Compared to other watches, this one uses real precious metal – 18K gold – to make its strap, buckle, and case. Its weight can be completely consistent with the original. This is a half-kilogram gold watch. Let me weigh it and see how much it weighs. You can see that its weight is 248 grams. This weight is exactly the same as the genuine one. Only by using real precious metal can you achieve such weight.
And this gold case is developed based on original data. This is a “Two-Gold” watch – also known as the Florentine hammering process. That means the particles on the strap and case sparkle in the light – very beautiful. They are all hammered by hand by master craftsmen – not machine‑made.
For this kind of watch, the case shape is very important. Our 26240 BA has thickness completely consistent with the original. Whether it’s the polished surface treatment or the chamfering and polishing – everything can match the original.
When we play with this AP gold watch, you must pay attention to one thing: the upper part of the strap is thicker and the lower part is thinner – it is a tapered (gradually thinning) process. Some other gold factories make the strap size uniform – those are not correct. This is the original style – a tapered strap. When you are choosing, you must pay careful attention to these areas.
The internal accessories – such as the dial, hands, and date wheel – are all customized based on original data, using top‑tier aftermarket parts. The gold color of its dial is matched to the genuine original. Under light, its sunburst radial lines are very full. You can see that – especially on the three‑eye chronograph – the sparkle and texture are the same as the genuine. Its hands are three‑dimensional. The date wheel is a thick, high‑quality replacement, filling the entire date window.
For this watch, the movement is a molded, non‑caliber (free‑sprung) 4401 integrated movement. What does an integrated 4401 mean? It means this movement is based on the genuine 4401 – replicating its structure, jewel positions, thickness, and all functions. This 4401 movement can achieve the true non‑reverse (flyback) chronograph function.
- 6 o’clock – running seconds hand
- 9 o’clock – chronograph minute counter
- 3 o’clock – chronograph hour counter
- The large central hand is the chronograph seconds hand
Through the two pushers (upper and lower), you can achieve the fully functional flyback chronograph.
The purpose of a customized modified watch is to restore it in every aspect – from the texture of its case, to its material and weight, to the color of the surface accessories, to the function and structure of its movement – achieving a comprehensive restoration. When you wear this watch, as long as you don’t send it to a professional agency for testing, there will be no flaws.
In fact, for this kind of gold watch, you’re essentially paying for the gold – it just happens to be turned into an 18K gold watch. If you modify this watch, you can enjoy the look and feel of a watch worth over one million yuan.
There are many AP watches – especially the gold models with the Florentine “Two-Gold” process – that can also achieve perfect results through our original data development.
This is an AP 26240 BA gold watch – a Two-Gold watch. If you like this watch, you can contact Bozwatch. If you like Bozwatch’s watch videos, please double‑tap to like and follow.
