Summary of Key Points about the Modified Patek Philippe Nautilus (Model 5712R – Gold Strap, Genuine Movement)
Here are the essential features:
1. Model & Market Context
- Model: Patek Philippe 5712R Nautilus (rose gold, full gold strap)
- Secondary market price: 1.6–1.7 million yuan – extremely expensive
- Through modification/customization, customers can spend less money to enjoy and own it
2. Material & Weight
- Case and strap made from real AU750 18K rose gold
- Total weight: 195 grams – exactly matches the genuine
- Weight is critical – using any other material cannot achieve this weight. Buyers must pay attention to weight when choosing gold‑strap watches.
3. Movement – Original Genuine Patek 240
- Upgraded with an original genuine 240 movement
- Why use a genuine movement? The 5712 has a transparent caseback – ordinary people will check whether the movement matches the genuine. A genuine movement eliminates that tell.

- 5 o’clock – small seconds hand
5. Budget Option – Clone Movement
- If budget is insufficient, can use a post‑production one‑piece 240 clone movement (integrated)
- It can also achieve all functions – suitable for lower budgets
6. Dial, Hands & Moon Phase – Top‑Tier Aftermarket
- Developed based on original data
- Dial: Golden color – matched by adjusting to the genuine color; very accurate; under different light conditions, radial pattern feels very nice
- Hands: Central axle upgraded to reach the same level as genuine
- These are high‑quality replacement parts, not original
7. Gold Case Craftsmanship – Key Details
The watch is a gold watch (full gold case and strap). Many factories make gold cases, but quality varies. Buyers must pay attention to:
| Aspect | What to Look For |
|---|---|
| Upper cover shape | Not a pure circle – has a corner with very distinct edges |
| Brushing (wire drawing) | Very delicate on the upper cover |
| Crown curvature | Just right – slightly protruding – developed from original data |
| Thickness | 8.3 mm – consistent with genuine |
| Nautilus beak (side profile) | Must be very three‑dimensional and vivid, not too round. A round beak (no bird‑shape) indicates a non‑standard case. |
| Strap adjustability | Slightly movable head – press‑fit adjustable strap |
| Strap middle beads | Every section has a slight bulge – raised bead – visible from the side |
8. Engravings & Hallmarks – Very Important
- Caseback engravings: PPC, dog head, AU750, scales – must be very three‑dimensional
- Clasp / buckle engravings: Clear lettering, accurate fonts
- A good gold case product has deep, sharp, three‑dimensional engravings
9. Key Quality Checklist for PP 5712R (Genuine Movement, Full Gold)

Concluding Comment
This video showcases the absolute top configuration for a PP 5712R Nautilus: a real 18K rose gold case and strap (total 195g) paired with a genuine Patek Philippe 240 movement. The genuine secondary market price of this watch is astronomical (1.6–1.7 million yuan), making it unattainable for most. The modified version allows a buyer to spend significantly less while achieving a watch that will pass almost all casual scrutiny – especially because the transparent caseback reveals a real Patek movement.
Strengths:
- Real 18K rose gold (195g) – correct weight, material, and color. Weight is the most obvious tell for a gold Nautilus, and this build nails it.
- Genuine Patek 240 movement – non‑regulated balance with counterweights, 22K gold rotor, gold sleeve, clear gilded engravings. This is the ultimate upgrade for a transparent‑caseback watch.
- CNC original data case – correct upper cover shape (edges/corners), correct crown protrusion, correct thickness (8.3mm), and most importantly, a sharp, three‑dimensional Nautilus beak (not rounded). Rounded beaks are a common flaw on inferior cases.
- Adjustable strap with raised middle beads – the bracelet has micro‑adjustment and the correct raised bead profile, matching the genuine.
- Deep, three‑dimensional hallmarks – PPC, dog head, AU750, scales – hand‑chiseled or deep CNC, clear and accurate.
- Dial and hands – high‑quality aftermarket parts that closely match the genuine golden color and radial pattern.
- Authentication possible – genuine movement and parts can be verified by domestic authoritative agencies.
- Budget option – if the genuine movement is too expensive, a clone 240 movement that achieves all functions is available.
Weaknesses / Considerations:
- Dial, hands, moon phase are aftermarket (unless further upgraded to genuine). While top‑tier, they are not original Patek parts.
- Clone movement option – if choosing the budget path, the movement is not genuine and will not pass professional inspection.
- Still an unauthorized replica – the case, bracelet, and dial carry Patek trademarks without permission, even though the movement is genuine.
- High cost – a solid 18K gold case/bracelet plus a genuine Patek movement is not cheap. This is for serious collectors with substantial budgets.
Final verdict: For the discerning collector who demands the highest possible authenticity in a modified Nautilus 5712R, this build – real 18K gold case/bracelet + genuine Patek 240 movement + top‑tier aftermarket dial/hands – is arguably the best available. The visible movement is the hardest part to fake, and using a genuine movement eliminates that concern entirely. The case details (beak shape, crown height, thickness, brushing, hallmarks) and bracelet details (adjustability, raised beads) are all executed to a very high standard.
The video provides excellent practical checks for buyers: feel the weight (195g), examine the beak (sharp and 3D, not round), check the upper cover edges (not a pure circle), verify the thickness (8.3mm), and inspect the engravings (deep and clear). For those with a smaller budget, the clone 240 movement version offers a functional alternative, though it will not fool an expert. As always, independent verification of the gold purity (XRF) and the movement’s authenticity (if claimed as genuine) is strongly recommended. For the right buyer, this modified 5712R represents the pinnacle of what is achievable in the custom watch space – a genuine Patek movement inside a correctly crafted solid gold case.
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 all watch lovers can avoid pitfalls and find their own “Bole” (discerning patron).
Some fans later sent me private messages wanting to know about a PP 5712R gold strap style with a top‑modified configuration. They asked me to make a video to authenticate it. Well, today it’s here.
This watch is a PP 5712R in the gold bracelet style. It is upgraded with an original genuine 240 movement and made of solid 18K rose gold. This watch can truly be called a top configuration.
The secondary market price of the Nautilus 5712R has reached 1.6 to 1.7 million yuan – an extremely exaggerated price. Through modification and customization, customers can spend less money to enjoy and own it.
As usual, for this kind of gold watch, if we want to play it perfectly, we use real precious metal – AU750 18K rose gold – to achieve the same material, same weight, same color, and same texture as the original.
Let’s weigh it together. What is the weight of a watch like this? The 5712R is actually very heavy. You can see the entire watch weighs 195 grams – completely consistent with the genuine. This watch is customized with precious metal to achieve that weight. If you use any other material, you cannot reach this weight. So when customers choose gold‑bracelet watches, they must pay attention to the weight.
As I just mentioned, this watch is upgraded with an original genuine 240 movement. Because the 5712 is a multi‑function watch. If you upgrade with a genuine movement – especially with a transparent caseback – ordinary people will only check whether your movement matches the genuine. They can’t easily spot differences in the dial, hands, or moon phase from the front. So for a transparent‑caseback style, if you have enough budget, I actually recommend upgrading with an original movement.
This is an original genuine 240 movement – look at its craftsmanship details. It has a true free‑sprung (non‑caliber) structure. There are counterweights around the balance wheel. On its bridges, you see gold chatons, and the polishing is very, very delicate. The engravings – these are original movement engravings – very clear, in gilded lettering. The rotor is also 22K solid gold. The craftsmanship of these genuine movements all meet the highest standards.
For genuine accessories like these, or genuine movements used in custom watches, customers can send them to a more authoritative domestic appraisal agency to issue a professional inspection report.
Upgrading with this original 240 movement achieves all its functions:
- 10 o’clock – power reserve display
- 7 o’clock – moon phase
- Outer dial – calendar function
- 5 o’clock – small seconds hand
If your budget is tighter, you can also use our post‑production integrated 240 movement – it also achieves all functions.
For this watch, the surface accessories – dial, hands, moon phase – are all customized based on original data. The golden color of the dial is matched to the genuine – very accurate. Under different lighting conditions, the sunburst pattern is very nice. From the side, the central axis has been upgraded to reach the same level as the genuine. See?
Now, this is a gold watch. There are many factories making gold watches. When customers choose this kind of product, they must pay attention to the craftsmanship details of the gold case.
First, look at the front – the bezel is not a perfect circle. It has distinct corners with very sharp edges. The brushing on the bezel is very delicate. Look at the side – the curvature of the crown is just right, slightly protruding. All of this is developed based on original data.
Look at the side thickness – the Nautilus is 8.3 mm thick – consistent with the genuine. Pay attention to thickness when choosing.
Now look at the Nautilus beak on the side. A truly good case – when you choose, you can examine the side beak. If the beak is too round, without a clear bird‑like shape, then that case is not a standard case set. A really good case will have a very three‑dimensional, vivid Nautilus beak.
Now the bracelet – this style has a slightly movable head adjustment. It’s a press‑fit, adjustable strap. Pay close attention when examining the bracelet. Also, the engravings – you must carefully distinguish them. Choose ones with very clear and accurate lettering.
Look at the bracelet – the center beads of each link have a slight bulge. From the side, it’s even clearer – a raised center bead. Customers must pay attention to these details.
Second, the engravings on the caseback – such as the PP mark, the dog head, AU750, and the scale. A good gold case product will have very three‑dimensional engravings. Pay close attention to this aspect.
This is a PP 5712R Nautilus – modified and upgraded with an original genuine movement – a top‑notch product.
