Concluding Comment
This nineteenth video returns to the PP 5712R Nautilus with a focus on real 18K gold and a cost‑conscious value proposition. Unlike the previous genuine‑movement build (which was extremely expensive), this version uses a top‑tier aftermarket dial, hands, and moon phase paired with a clone 240 movement (with upgrade options). The case and strap are made from real 18K gold (193g), giving the watch intrinsic bullion value and correct weight.
Strengths:
- Real 18K gold (193g) – at current gold prices, the melt value alone is substantial (well over 100,000 yuan). This is not a plated watch; it is a solid gold product.
- CNC original data case – correct crown height, chamfers, beak curvature, and thickness. The emphasis on the beak not being “too flat” and the crown not being “too high” provides useful quality checks.
- Strap taper and protruding middle bead – correct Nautilus bracelet geometry, including the slight curvature of the raised bead.
- Fine‑tuning buckle – a modern Patek feature (adjustable clasp) correctly replicated.
- Deep, 3D Calatrava logo and hallmarks – AU750, dog head, scales, PBC – all perfectly engraved.
- Flexible movement options – clone 240 (standard), non‑regulated with 22K gold rotor (upgrade), or genuine 240 (premium). Buyers can choose based on budget.
- Value proposition clearly stated – for ~100,000 yuan, you get the look, feel, and weight of a 1.4 million yuan watch. The gold content alone justifies a significant portion of the price.
Final verdict: This modified 5712R targets the buyer who wants a solid gold Nautilus with correct weight and finishing, but who does not need genuine Patek movement or dial. The use of real 18K gold (193g) means the watch has intrinsic value – it is not a “waste of money” in the same way a plated steel replica would be. The CNC case and strap, with attention to the beak shape, crown height, chamfers, and fine‑tuning buckle, demonstrate high craftsmanship.
For collectors who find the genuine 5712R (1.4 million yuan) unattainable, this build offers a luxury alternative that is still expensive (over 100k yuan) but far more accessible. The ability to upgrade the movement (to non‑regulated with 22K rotor, or to genuine 240) allows buyers to incrementally improve authenticity. The key is to verify the gold purity (XRF testing) and to understand that the dial/hands/moon phase are aftermarket. For the informed buyer who values real gold and precise case finishing, this is one of the best 5712R builds available. As always, independent authentication of the movement (if paying for genuine) and gold content is strongly recommended.
Hello everyone, this is Bozwatch Reviews.
Every watch is a work of art, a testament to time. I’m a fanatic who loves them. I also hope that all watch enthusiasts can avoid pitfalls and find their own “Bole” (discerning patron).
Later, some fans messaged me wanting to buy the best modified and upgraded PP 5712R Nautilus on the market – the most perfect one – and it must be made of precious metals. They asked me to make a video with them to authenticate such a watch.
In fact, the PP 5712R Nautilus is a very popular style in the Nautilus series. Bozwatch paid out of his own pocket to buy from a merchant the PP 5712R Nautilus – the most perfectly upgraded and modified version.
This watch has its case and strap made of 18K gold. It is then paired with the most top‑tier aftermarket dial, hands, and moon phase developed from original data, along with a 240 movement inside.
First, let’s look at the overall feel of the watch. You can see the texture of 18K gold – very good. See? It’s still pretty good. This custom‑made 18K gold watch is the same as the genuine – customized with AU750 gold material. It achieves a certain sense of heft, which is reflected in its weight.
Let’s weigh it together and see how much this watch weighs. You can see the entire watch weighs 193 grams. This weight is exactly the same as the genuine.
Think about it – 193 grams of gold. You’re not just considering the watch’s value; just the gold weight alone is significant. Some people may ask why a custom‑made 18K gold watch costs over 100,000 yuan. Because the price of gold is really high now – the cost of making just the case is very high.
For that amount, what kind of feeling do you get when wearing it? It feels like you’re wearing a watch worth over one million yuan. The secondary market price of this genuine watch is about 1.4 million yuan. Through customization, modification, and upgrading, you can spend less money to achieve more – that is the ultimate purpose and meaning of modified watches.
For this watch, its case and strap are developed through CNC original data. Look at the brushing on the top cover – it’s well polished. The polished surface treatment and the finishing of the edges and corners are all very good, consistent with the original process.
Now look at the crown. The curvature of the crown is slightly higher than the middle case. Some gold case factories make the crown too high – that’s wrong. Every chamfer is rounded, and the chamfer grinding connects from top to bottom. See? This is a Nautilus – the beak shape. The curvature of the beak is developed based on original data – just right. The arc of the beak opening – some factories make the beak too flat – that’s all wrong. The thickness is exactly the same as the genuine.
What movement is used inside? It is a molded 240 movement. The engravings on the bridges are Geneva stripes – very deep. The movement can actually be upgraded – to a free‑sprung (non‑caliber) movement, to a 22K gold automatic rotor. If you have sufficient budget, you can also upgrade to an original 240 movement – no problem. When you choose, you can select according to your own budget, but make sure it’s a molded 240 integrated movement.
Now the dial accessories. The golden dial is a top‑level aftermarket dial developed from original data. The three‑dimensional hands are very nice. The moon phase is also a top‑tier aftermarket moon phase.
Now look at the strap. The Nautilus strap is very distinctive – the center bead protrudes, which feels very textured when touched. And the center bead doesn’t just protrude randomly – it has a certain curvature. See? From the side, you can see a slight curve. Also, the strap is thicker at the top and thinner at the bottom. Why can it be made this way? Because the genuine does the same. That means they found a form developed based on original data – all details benchmarked against the genuine.
Now look at the buckle. The Calatrava logo – very deep, see? It has a very strong three‑dimensional sense. This pattern is completely consistent with the genuine. Then open the buckle and look inside – see the full spelling of Patek Philippe and the precious metal hallmarks on the back – AU750, dog head, scale, and crown – all perfectly executed.
This is the standard of detail for a custom‑made 18K gold watch.
The strap also has a fine‑adjustment function. If you press both sides simultaneously, you can pull it out a little – it has a micro‑adjustment feature. See? This fine‑adjustment function is also consistent with the genuine.
This is the PP 5712R Nautilus – custom‑made with 18K gold and top‑tier aftermarket parts – a top‑of‑the‑line watch.
