Summary of Key Points about the Modified Patek Philippe Nautilus (Model 5712A – Steel Case, Top‑Tier Aftermarket)
Based on the latest video transcript (focusing on the PP 5712A Nautilus steel case), here are the essential features of this top‑tier modified watch.
1. Model & Case Material
- Model: Patek Philippe 5712A Nautilus (steel case, not precious metal)
- Case developed using CNC original data
2. How to Identify a Genuine CNC Case – Two Key Checks
- Side opening arc: The opening arc of the two “beaks” is higher than on ordinary market cases. Ordinary cases have a lower bend.
- Caseback removal: A genuine CNC case cannot be removed with a rubber ball – it is fixed with screws from the inside. Market cases can often be unscrewed easily with a rubber ball.
3. Dial, Hands, Calendar & Moon Phase – Top‑Level Aftermarket
- Developed with original data
- Dial: Color and sunburst radial lines are very full – “look great”
- Hands: Three‑dimensional (3D), not paper hands; proper central axis effect; strong texture under light
- Calendar: Outer ring with 31 numbers (date)
- Moon phase: Top‑tier aftermarket moon phase
- Special detail: Polished rivets on hour markers – ordinary watches do not have these
4. Case Brushing / Finishing
- The brushing on the front of the case is very delicate – what a top‑level modified 5712A should have
5. Movement – Free‑Sprung 240 Clone
- Non‑regulated (non‑caliber) 240 integrated open‑mold movement – best on the market
- Bridge engravings: Deeply engraved
- Rotor: 22K solid gold automatic rotor
- Claim: The back is over 90% close to the genuine – hard to tell without a genuine movement beside it for comparison
6. Strap / Bracelet
- Polishing and brushing are quite good – very delicate
- The raised center links are just right (not too high, not too low)
7. Clasp Options
- Old style: Two‑section safety buckle – press down, then close two safety clasps
- New style: Butterfly buckle – pops open directly when pressed (more convenient)
- Choice depends on personal preference
8. Overall Assessment
- This is the top‑level aftermarket version – the best modified 5712A available
- Question posed to viewers: Is it worth buying, or a waste of money?

Concluding Comment
This video focuses on the PP 5712A steel Nautilus – a steel‑case version (unlike precious metal builds). The emphasis is on CNC case accuracy and movement quality. The case identification methods (higher side opening arc and screw‑fixed caseback) are practical, actionable checks. The top‑tier aftermarket dial, hands, moon phase, and 3D hands with polished rivet details are high quality. The movement is a non‑regulated 240 clone with a 22K gold rotor and deep bridge engravings, claimed to be over 90% similar to genuine. The strap finishing and choice of clasp (old safety or new butterfly) are good. For collectors who want a high‑end steel Nautilus 5712A without paying the genuine price (which is still very expensive), this represents a top‑tier option. However, it is still an unauthorized replica. The video’s honest question – “Is it a waste of money?” – leaves the answer to the buyer’s perspective. For those who appreciate the craftsmanship and can accept the legal gray area, this modified 5712A offers excellent value compared to the genuine. As always, independent verification of the movement and case is recommended.
Hello everyone, this is Bozwatch.
Every watch is a work of art, a testament to time, and I am a fan of them. I also hope that watch enthusiasts can avoid pitfalls and find their own “Bole” (discerning patron).
Some fans have messaged me privately, wanting to buy the current market’s modified and upgraded PP 5712A Nautilus. They asked me to take a look and help them decide – is such a modified watch worth buying? Or is it a waste of money?
So I spent my own money to buy such a 5712A – a top‑level aftermarket version – to make a video for everyone, to show you what the best modified 5712A looks like.
First, you can see that this watch is a steel case watch. The case is developed using CNC original data. Let me teach you how to identify a real CNC case.
Look at the side – the arc of the opening. You can see the side opening arc of these two “beaks” is higher. On ordinary market cases, the curvature is not as high. Without this curved opening, the bend would be the same as the regular one – but then the bend would be too high.
Another thing is the caseback. On ordinary market cases, you can remove the caseback directly with a rubber ball. But on this CNC case, you can’t – it’s fixed with screws from the inside. That’s one way to identify a genuine CNC case.
Now let me show you the movement inside and the dial. These accessories are developed with original data – they are top‑tier aftermarket parts.
First, look at the dial. The color and sunburst radial lines – don’t they look great? Very full. Then the hands – they have a proper central axis effect. The hands are all three‑dimensional, not paper‑thin. Under light, you can see the texture is quite strong.
Now the calendar. The calendar is on the outer ring – see? The 31 numbers on the outer ring are the date. The moon phase is inside – it is also a top‑level aftermarket moon phase. The front accessories are all developed with original data.
Look at the details – for example, the polished rivets on the hour markers – ordinary market watches don’t have these. See? It’s really good.
Now look at the front of the case – the brushing is very delicate, isn’t it? This is what a top‑level modified watch should have. The details are truly perfect. The front is already very impressive.
Now let’s look at the movement on the back. This is also the best on the market – a free‑sprung (non‑caliber) 240 integrated open‑mold movement. You can see it’s non‑calibrated – you can see the free‑sprung structure. The bridges have deep engravings. And the rotor is a 22K solid gold automatic rotor. The back is very close to the genuine – I can say it reaches over 90% similarity. If you don’t have a genuine movement right next to it for comparison, it’s hard to tell at a glance.
Now the strap. You can see the polishing and brushing on the strap – quite good, very delicate. The raised center links are just right – not too high, not too low.
Now the clasp. There are two types of clasps. One is the old‑style two‑section safety buckle – you press it down and then close the two safety clasps. The other is the new butterfly buckle – it pops open directly when pressed. The butterfly buckle is more convenient. It mainly depends on your preference – you can choose the old style or the new style.
This is the PP 5712A – a top‑level aftermarket version. A simple watch sharing. This is the best modified 5712A available.
