Here are the essential features of this high‑end modified Patek Philippe Nautilus:
1. Model & Configuration
- Model: Patek Philippe 5711/1A (Nautilus)
- This is a top‑configuration modified watch
- Uses an original genuine Patek Philippe 324 movement and an original genuine calendar for upgrading
2. Why Use a Genuine Movement?
- Most Nautilus watches have a transparent caseback – the movement is visible
- Using a genuine movement achieves a more perfect effect with no visible tells
- Recommended for those with sufficient budget who pursue perfection
3. Genuine Movement Features (Calibre 324)
- Truly unregulated (non‑regulated) structure – balance wheel has counterweights
- Bridge engravings: SOP and PP marks – all engraved with gilded font (not printed)
- Movement workmanship is very delicate and nice
- Automatic rotor: Real 18K gold rotor
4. Alternative Movement Option (Lower Budget)
- On the right in the comparison: A custom‑made PP 324 integrated movement (clone)
- Has a real Calatrava structure – almost no big difference from genuine
- Suitable for those with lower requirements or budget
5. Dial & Hands – “Daimler Accessories” (Top‑tier Aftermarket)
- Dial color, radial pattern effect, and font are highly restored based on genuine colors and fonts – very close
- Calendar is original genuine (mentioned)
- For higher budget: Dial and hands can also be upgraded with original genuine accessories
- Genuine accessories and movements can be sent to domestic authoritative testing agencies for professional inspection reports (they are expensive)
6. Case Craftsmanship – Critical “Beak Shape” Detail
- A good Nautilus case has a “beak shape” on the middle case (side profile)
- This case is CNC original data – developed with a sharp, three‑dimensional beak
- Incorrect version: Beak is round, has no beak shape at all – that watch has problems
- Quality check: If a friend wears a Nautilus with a rounded beak, their watch is problematic
7. Strap & Buckle
- Strap developed with CNC original data
- Calatrava logo and raised beads in the strap – both consistent with genuine
- Buckle engravings: Clear; brushed finish on back of buckle matches genuine
8. Overall Philosophy
- These high‑end Nautilus models have very high prices in the secondary market
- Through customization, you can spend less money to enjoy and own such a watch
9. Key Quality Checklist for PP 5711/1A (Genuine Movement Version)
| Component | What to Look For |
|---|---|
| Movement | Genuine Patek 324 (or high‑quality clone as alternative) – unregulated balance with counterweights; gilded engraved bridges; 18K gold rotor |
| Calendar | Original genuine |
| Dial & hands | Original genuine (high budget) or top‑tier aftermarket (“Daimler”) with correct color, radial lines, font |
| Case – “beak shape” | Middle case side must have a sharp, 3D beak – not rounded (rounded = wrong/fake) |
| Strap | CNC original data; correct Calatrava logo; raised beads match genuine |
| Buckle | Clear engravings; proper brushed finish on back |
| Caseback | Transparent – shows movement (reason for genuine movement) |
For the discerning collector who wants a Nautilus that will pass close inspection – even with the caseback open – this genuine‑movement build is the best possible replica/modification. The visible movement is the hardest part to fake, and using a real Patek 324 solves that completely. The “beak shape” quality check (sharp vs. rounded) is a brilliant, simple indicator of case quality that applies even to lower‑tier builds. Bozhong’s tiered approach – genuine movement vs. clone, genuine parts vs. aftermarket – allows buyers to choose according to budget. This video serves as both a showcase and a buyer’s guide. As always, transparency and due diligence (independent authentication of the movement) are essential. For those who can afford it, this is the closest thing to a genuine Nautilus without paying the astronomical secondary market price.
Hello everyone, this is Bozwatch Reviews.
Every watch is a work of art, a testament to time, and I am a fanatic who is obsessed with them. I also hope that all watch enthusiasts can avoid pitfalls – I am your own “Bole” (discerning patron).
Today, I bring you a PP 5711/1A with the top configuration in stainless steel (Inox). This watch uses an original genuine double‑P 324 movement and an original calendar for the upgrade.
So why use an original genuine movement? Because the Nautilus watch most often has a transparent caseback – the movement can be seen from the back. If you have sufficient budget and pursue perfection, you can use this original genuine movement. Using a genuine movement achieves a more perfect result.
Look at this – this is the structure of an original genuine movement. It is a true free‑sprung (non‑caliber) structure. Around the balance wheel, there are counterweights. The bridges include the PP mark and other engravings – all are executed in gilded lettering. The movement is very delicate, and the craftsmanship is excellent. The rotor is a real 18K gold automatic rotor.
If you don’t have such high requirements for the movement, you can use our later‑made aftermarket integrated movement. On the right is a double‑P custom‑made 324 integrated movement – it has a true free‑sprung structure. There is almost no big difference.
In fact, for this kind of modified and customized watch, everything is made according to your budget and needs. If your budget is high, you can directly choose the upgraded original movement.
The dial and hands are customized based on original data – these are aftermarket accessories. What does “aftermarket accessories” mean? It means our dial – the color, the sunburst pattern effect, and the fonts – are highly faithful to the genuine, based on the original colors, fonts, and radial lines. In fact, it’s very close.
The calendar – as just mentioned – is an original genuine calendar. If your budget is higher, for the dial and hands we can also use original genuine accessories. That’s all fine.
For watches built with genuine accessories and genuine movements, you can send them to a domestic authoritative testing agency to issue a professional inspection report. Because such genuine accessories and genuine movements are actually quite expensive.
Now, for a Nautilus watch, the case is critical. A good Nautilus case – its bezel, polishing, and brushing are very delicate. You can see that – including the polished surface treatment.
When playing with a Nautilus watch like this, you must pay attention to one thing: the middle case on the side has a beak shape. Our case is CNC original data – we developed a beak case. The beak is very sharp and three‑dimensional. This is the case that matches the original version. When you are choosing, you must carefully distinguish. If you have a friend who wears a Nautilus and his watch has a relatively round beak – no beak shape at all – then there may be some problems with his watch.
For this watch, the strap is also developed by us with CNC original data – customized. Look, this is the unopened strap. Whether it’s the Calatrava logo or the raised beads in the strap, everything is consistent with the original. Including the engraving on the buckle, the brushed finish on the back of the buckle, and the engraving on top. See? This is what a good product needs to have – such craftsmanship.
In fact, these highly sought‑after watch models have very high prices on the secondary market. Through our customization, we help you understand and let you spend less money to enjoy and own such a watch.
This is a PP 5711/1A – equipped with an original genuine movement, original calendar, and a case developed with CNC original data, along with dial and hands.
