Concluding Comment
This sixteenth video focuses on the Patek Philippe Nautilus 5712R – a model with a genuine secondary market price around 500,000 yuan. Unlike the 5711 (time/date only), the 5712 features a moon phase and a more complex dial layout, making it a more challenging replica to execute well. The modified version described here aims to deliver a high‑end alternative at a fraction of the cost (tens of thousands of yuan).
Strengths:
- CNC original data case with 5‑axis machining – ensures correct proportions, including the critical opening arc curvature (a common mistake on lower‑end factory goods).
- Top‑level alternative dial, hands, and moon phase – developed from original data. The black‑gray dial for the leather strap version is noted as more accurate (darker colors reduce visible color differences).
- Frosted moon phase – a subtle detail that many replicas get wrong.
- Clone 240 integrated movement – Patek’s calibre 240 is a ultra‑thin automatic movement with a micro‑rotor. Replicating this is technically demanding. The movement can be upgraded to a non‑regulated version or even a genuine 240 movement for those with higher budgets.
- Deep, vivid engravings – both on the caseback (750, dog head, scales) and on the buckle (“A Lei” / Nautilus spelling, PPCC, AU750, balance, dog head). Depth and clarity of engravings are key quality markers.
- Butterfly buckle – correctly executed with deep lettering and precious metal marks on the back.
Weaknesses / Considerations:
- Dial, hands, moon phase are aftermarket – even if “top‑level,” they are not genuine Patek parts. The dial color difference between leather strap and bracelet versions is noted, but buyers should confirm accuracy.
- Movement is a clone (unless upgraded to genuine 240). The clone 240 integrated movement is less common than the 324 clone; its reliability and finish may vary.
- Weight is not mentioned – for a precious metal (18K rose gold) watch, weight is critical. Unlike previous videos, this transcript does not provide a weight measurement. Buyers should verify that the case is real 18K gold (not plated) to achieve correct heft.
- Still an unauthorized replica – carries Patek Philippe trademarks without permission.
Final verdict: This modified 5712R Nautilus targets collectors who want the more complicated moon‑phase Nautilus (5712) rather than the simpler 5711. The emphasis on the correct opening arc curvature, deep engravings, frosted moon phase, and the clone 240 movement (with genuine upgrade option) shows attention to the unique challenges of this model. The price (tens of thousands of yuan) is significantly higher than standard replicas but still a fraction of the genuine 500,000 yuan market price.
However, the lack of a stated weight is a notable omission – for a precious metal 5712R, weight is a primary authenticity check. Potential buyers should independently verify that the case is solid 18K rose gold (e.g., XRF testing) and not just heavy plating. The option to upgrade to a genuine Patek 240 movement is attractive for perfectionists, but that will substantially increase the cost. As with all such products, buyers must be fully informed that this is an unauthorized replica – regardless of how well it is crafted. For the enthusiast who wants a well‑executed 5712R for study or personal enjoyment, this build appears to represent a high standard, provided the material claims are verified.
Hello everyone, this is Bozwatch Reviews.
Every watch is a work of art, a testament to time, and I am a fan of them. I also hope that all watch enthusiasts can avoid pitfalls and find their own “Bole” (discerning patron).
Because some fans have messaged me privately, wanting to buy the best modified PP 5712R Nautilus currently on the market – and it must be made of precious metals. So today, I have such a PP 5712R Nautilus. I will share with you what kind of Patek Philippe 5712R Nautilus is worth buying, and what level of craftsmanship to look for.
The current secondary market price for the PP 5712R Nautilus is about half a million yuan, but the customer doesn’t have that much budget. So, considering that, we customize such a 5712R Nautilus to interpret and enjoy.
In fact, for a watch made of 18K gold and precious metals, to be honest, it depends on how you look at it. The price of this custom watch is still tens of thousands of yuan – not cheap. However, compared to the genuine market price, it’s only a fraction of the original. So it’s a good deal – the ultimate value proposition of a modified watch.
Like this watch, its case and buckle are all made through CNC original data, finely carved by a five‑axis CNC machine. The details of the case and the buckle are all comparable to the genuine.
According to the merchant, this watch – the dial, hands, moon phase, and the movement – are at the highest level on the market. The internal accessories – dial, hands, and moon phase – are developed with original data. These are top‑level aftermarket parts.
You should notice that the leather‑strap version of the 5712 and the gold‑bracelet version have different dial colors. See? The leather‑strap version presents a black‑gray color, while the new model has a golden hue. There is a difference here. But the leather‑strap style dial is actually more faithful to the original, because the darker the color, the less color difference there is.
You can see that the printing, the fonts, and the sunburst radial lines on the dial are very full. According to the merchant, this is the most powerful, most advanced replacement dial. It is indeed worthy of its name – the workmanship is quite good.
Now look at the hands. You can see the central axis effect – very full. The central axis is well finished. All the hands are aftermarket three‑dimensional hands. The hands are also quite good.
The moon phase is also a high‑quality aftermarket part. You can see it uses a frosted moon phase disk – still very good. The surface accessories are said to be the highest level on the market, and that is well deserved. The workmanship is quite good.
Now look at the movement on the back. According to the merchant, it is a molded 240 integrated movement that can realize all its functions. This movement can also be upgraded – to a free‑sprung version with gold engraving, or even to an original genuine 240 movement. That’s the movement on the back.
Now let’s look at the gold case – to see if the workmanship is up to standard. First, look at the front. The brushing on the front is quite delicate. Every chamfer has been rounded and polished – very good. The workmanship is excellent.
Now look at the side. The thickness is very good, and the opening arc is just right. See? The opening arc has a nice curve. Only those factory goods on the market have the wrong curvature. This arc is up to standard – still very good.
Now look at the caseback – the precious metal engravings on the four corners. The 750 mark, dog head, crown, and scale – these four engravings are very deep, which is very good.
Now let’s look at the clasp. You can see the word “Nautilus” – actually it’s the full spelling of “Nautilus” – on the clasp. This engraving is very deep – very good. It’s a butterfly buckle – a push‑button butterfly buckle. Look at the back of the clasp. The back has the full spelling of Patek Philippe and precious metal hallmarks – PP, AU750, scale, dog head – very deep, very good, and very vivid.
In fact, for a watch like this, customized and crafted with this technique, you can buy one to study and enjoy – it’s totally fine. For modified watches like this, is it worth buying for watch collectors? If you like this watch, you can search for it yourself.
