- Case made from real precious metal AU750 18K platinum (or white gold)
- Developed using original CNC data – restores original material, weight, and color
2. Weight – Critical Differentiator

- Upgraded clone (higher budget): Converted to non‑regulated (no card) with:
- Counterweights on balance wheel
- Re‑gilded bridge engravings
- 22K gold automatic rotor

5. Case Craftsmanship – CNC Original Data
- Developed by 3D scanning a genuine watch
- Brushing (wire drawing): Very delicate
- Polishing surface treatment: Correct
- Upper cover shape: Not a pure circle – has edges and corners
- Chamfering and polishing: Very delicate
- Nautilus beak (side profile): Very vivid, three‑dimensional – the correct beak shell
6. Buckle / Clasp Details

Concluding Comment
This video focuses on the PP 5712G Nautilus in platinum (or white gold) – a precious metal version that is often faked using steel cases. The single most important check is weight: genuine platinum/white gold 5712G weighs ~140 grams, while a steel case version weighs only ~90 grams. Anyone who knows the genuine weight will immediately spot a steel fake.
Strengths:
- Real 18K platinum/white gold case – correct weight (140.3g) and material. The weight difference from steel (50g+) is a dead giveaway that this build addresses.
- CNC original data case – delicate brushing, correct polishing, proper edges/corners, and a three‑dimensional Nautilus beak shape.
- Clear upgrade paths – buyers can choose:
- Cost‑effective: top‑tier aftermarket dial/hands/moon phase + standard card‑regulated 240 clone.
- Premium: genuine dial/hands/moon phase + upgraded non‑regulated 240 clone with 22K rotor.
- Ultimate: genuine 240 movement.
- Hand‑chiseled hallmarks – AU750, dog head, scales, PBC on both the buckle interior and caseback. Deep, clear engravings are a hallmark of a quality gold case.
- Buckle engraving – “Nautilus” correctly spelled and deeply engraved.
- Practical advice – the video clearly states the price difference between movement versions (over 10,000 yuan) and advises buyers to choose according to budget.
Final verdict: This modified 5712G addresses the most common tell of precious metal replicas – weight. A steel case fake (~90g) is instantly distinguishable from a genuine platinum/white gold watch (~140g). By using real 18K white gold (or platinum), this build achieves the correct heft and feel. The CNC case with correct beak shape, delicate brushing, and hand‑chiseled hallmarks meets high finishing standards. The movement options allow buyers to choose between a cost‑effective card‑regulated clone and a more accurate non‑regulated clone with 22K gold rotor.
For collectors who want a 5712G Nautilus – a white gold/platinum watch that is even rarer and more expensive than its rose gold counterpart – this modified version offers a compelling alternative. The weight alone will pass casual inspection, and the detailed case finishing will satisfy most enthusiasts. As always, buyers should independently verify the gold purity (XRF testing) and, if paying for an upgraded or genuine movement, authenticate it. The video’s emphasis on the weight difference (140.3g vs. ~90g) is the single most useful takeaway for anyone comparing products in this market.
Hello everyone, this is Bozwatch.
Every watch is a work of art, a testament to time, and I am a fanatic believer in them. I also hope that watch enthusiasts can avoid pitfalls and find their own “Bole” (discerning patron).
Later, some fans sent me private messages wanting to know about the best modified and upgraded PP 5712G platinum Nautilus on the market, and asked me to make a video with them to authenticate it. Well, today it’s here.
This watch is developed from CNC original data and made of real precious metal – AU750 18K platinum (white gold). For a watch made of platinum, it can faithfully restore the original material, weight, and color.
So what is the weight of this watch? As usual, let’s weigh it together. You can see that its weight is 140.3 grams. This weight is completely consistent with the genuine.
But most cases on the market are “dry cases” (steel or lightweight alloy) – they weigh only about 90 grams. That means if you have some knowledge and someone weighs your watch, they might discover the weight is wrong.
For this watch, the surface accessories and the movement are also refined. If you have enough budget, you can use an original genuine dial, hands, moon phase, and an original 240 movement for modification and upgrade. If your budget is tighter, you can use our aftermarket accessories.
So what do aftermarket parts mean? It means the accessories currently installed are highly faithful to the genuine – based on the original dial’s color, sunburst pattern effect, and fonts, to restore its luster. The texture and shine inside the dial are very strong. See? This option is more cost‑effective. These accessories match the genuine very well.
The movement currently installed is a molded integrated 240 movement. What does integrated movement mean? It means this movement is based on the original genuine 240 movement – its structure, gear positions, and thickness – fully restored. Currently, it is a regulated (index‑adjusted) movement.
If your budget allows, we can help you upgrade it further – convert it to a free‑sprung (non‑caliber) movement, re‑gild and engrave the bridges, and replace the rotor with a 22K gold automatic rotor. After this upgrade, the movement will be much closer to the original 240.
What does a modified movement look like? Look at the movement on the right side of the screen. You can see it is truly free‑sprung – there are counterweights around the balance wheel. The bridges have been re‑engraved with gilded lettering. The rotor is a 22K solid gold automatic rotor. Compare that to an ordinary 240 movement – which is a regulated movement with a visible index regulator. The difference in price between these two movements is over ten thousand yuan. You can choose according to your budget. These are the two main movement types on the market – be careful to distinguish them.
Now, for our gold case – it is developed and produced using original data. What does that mean? We take a genuine Nautilus, place it in a 3D CNC machine, and scan its data. Then we produce the case. You can see that the brushing is very delicate, including the polished surface treatment. The bezel is not a perfect circle – you can see the distinct edges and corners. The polishing and chamfering are very fine.
Look at the side – the Nautilus beak shape is very vivid and three‑dimensional. This is the correct beak case. The engravings on the clasp – whether it’s the “Nautilus” lettering, the inside of the clasp, or the precious metal hallmarks – are all exactly the same as the genuine. Here you see AU750, dog head, scale, and crown – all hand‑chiseled by our master craftsmen. For a gold case, the details of these engravings are very, very important.
Including the engravings on the caseback – the 750 mark, the scale, the crown, and the dog head – all hand‑chiseled and very, very clear. When choosing, you must carefully distinguish good from bad.
