Here are the essential features of this top‑tier modified Patek Philippe Aquanaut :
1. Model & Nickname
- Model: Patek Philippe 5167R – rose gold Aquanaut
- Commonly called the “Rose Gold Aquanaut” or “Grenade” (due to case shape)
2. Material & Weight
- Case and buckle custom‑made from 18K rose gold (real precious metal)
- Total weight: 116.8 grams – exactly matches the genuine
- Developed using original CNC data – finely carved by a 5‑axis machine, then hand‑finished by master craftsmen
3. Case Shape – Critical Detail
- The Aquanaut case is not purely round – it has a specific “grenade” shape with distinct edges and corners
- Correct version: Edges and corners are preserved, sharp and defined
- Incorrect version (many factories): Edges are smoothed out / rounded off – this is wrong
- This edge/corner detail is a key quality differentiator
4. Dial, Hands & Calendar (Top‑tier Aftermarket)
- Dial color: Very full, matches genuine exactly
- Radial pattern effect: Correct
- Scale (hour markers): Three‑dimensional feeling, very good
- Hands: Three‑dimensional hands (not flat “paper hands”) – strong 3D effect under light
- Calendar: Thick calendar – fills the entire calendar window (not shallow)
- These are described as the best aftermarket parts available
- Option: Can also be upgraded with genuine original accessories (dial, hands, calendar) for even higher authenticity
5. Movement
- Currently uses a domestic 324 integrated movement (clone of Patek’s calibre 324)
- Modified to be non‑regulated (unregulated) structure
- Bridge engravings: Has Oxford (Geneva stripe) engravings – these are genuinely engraved, not printed (many market versions have printed fonts, which lack depth)
- Automatic rotor: Custom 18K gold rotor (matches genuine material and color) – market versions often use copper rotors
- Movement similarity claim: ~98% close to genuine – ordinary people can hardly tell the difference
- Upgrade option: Can install a genuine 324 movement (more expensive)
6. Caseback & Hallmarks
- Four precious metal hallmarks on the caseback:
- AU750 mark
- Dog head mark
- PBC (or similar) mark
- Scales mark
- These engravings are developed from original data – font and pattern are very finely engraved and perfect
- Inferior versions have poor, blurry hallmarks
7. Buckle (Butterfly Clasp)
- Latest style – butterfly buckle
- New Patek logo is clearly engraved
- Precious metal marks also present on the back of the buckle (AU750, dog head, scales)
- Calatrava cross logo on the back of the buckle – done very perfectly
8. Overall Philosophy
- Modified watch purpose: Spend less money to achieve more – closer to original, less embarrassment when wearing
- Every detail (case shape, hallmarks, movement engraving, rotor material) developed to match genuine

This modified PP 5167R represents the state‑of‑the‑art for Aquanaut replicas – combining real 18K rose gold, a correctly shaped case (with sharp grenade edges), an engraved‑bridge clone 324 movement, and an 18K gold rotor. The attention to hallmarks, buckle details, and calendar thickness sets it apart from lower‑tier products. For collectors who desire the look and feel of a rose gold Aquanaut – a watch that costs a fortune and is nearly impossible to buy at retail – this custom build offers a realistic alternative with significant intrinsic gold value.
However, as with all such products, transparency is essential. The buyer is paying for real gold, skilled case finishing, and a high‑quality clone movement – not a genuine Patek Philippe. Bozhong’s emphasis on the grenade case edges (sharp vs. rounded) and engraved vs. printed movement bridges provides two excellent, practical quality checks that are often overlooked. For the informed enthusiast who accepts the legal and ethical gray area, this modified Aquanaut is arguably one of the most impressive replicas on the market today.
Hello everyone, this is Bozwatch.
Every watch is a work of art, a testament to time, and I am a fanatic of them. I also hope that all watch enthusiasts can avoid pitfalls and find their own “Bole” (a discerning patron).
Later, some fans sent me private messages wanting to buy the best modified and upgraded PP 5167R rose gold Aquanaut. They asked me to make a video to help authenticate it. So today, Bozwatch spent his own money to buy such a watch from a merchant – a 5167R rose gold Nautilus.
This rose gold Aquanaut is developed and customized using original data – an 18K gold case and buckle. Its material is completely consistent with the genuine, so its weight is exactly the same. Let’s weigh it together. See how much this watch weighs. You can see it weighs 116.8 grams – close to 117 grams. This weight is completely consistent with the genuine.
Because it uses 18K solid gold to customize the case, and such a solid gold case is made using original CNC data, finely carved by a five‑axis machine. Its case shape, the brushing, and the polishing are all made 1:1 with the original, executed by hand by master craftsmen.
You can see that the brushed finish on the case is very delicate. Look at the treatment of its edges and corners. You can see that it has a grenade‑like shape – it’s not purely round. It has distinct facets. See this edge? That’s the grenade shape. Many other factories will smooth out the edges and corners – that’s completely wrong. That case shape is incorrect. A case with defined edges and corners like this – that’s the correct version.
Now look at the internal accessories. The dial color is very rich and full – completely consistent with genuine parts. Such accessories are developed with original data, using the highest‑level aftermarket parts. Its dial color, sunburst radial pattern, and the three‑dimensionality of the hour markers are all very good. Its hands are aftermarket three‑dimensional hands – not flat paper‑thin hands. See? The three‑dimensional effect is very strong under light.
Then the date wheel. This is a replacement thick‑fill date wheel that fills the entire date window. Such accessories are the best – custom parts for later upgrades. However, if some customers pursue perfection, you can also upgrade with genuine accessories – original dial, hands, or date wheel – there’s no problem.
Third, the movement. This watch currently uses a domestic 324 integrated movement, modified to be free‑sprung (non‑caliber). The engraving on the bridge has a Geneva stripe (Côtes de Genève) pattern. Many 324 movements on the market have printed engravings – not real engravings. The depth difference is very large. Also, the rotor on the back is an 18K gold automatic rotor. Most automatic rotors on the market are made of copper. An 18K gold rotor is exactly the same as the genuine – same material, same color.
So a modified watch is developed to look exactly like the genuine. Its main purpose is to be as close as possible to the original, so you can wear it without feeling awkward.
The accessories of this watch are the best available on the market – the highest‑level aftermarket parts, including the dial, hands, date wheel, and the movement. The movement can also be upgraded with a genuine 324 movement, but of course that would be more expensive. In fact, the current movement already achieves about 98% similarity – very good. Ordinary people can hardly tell the difference.
Now, the case. You can see the caseback has four‑corner precious metal hallmarks – the AU750 mark, the dog head, the scale, and the crown. These four precious metal marks are very important. Such engravings are developed based on original data. Their fonts and patterns are very finely engraved and perfect. Ordinary ones are relatively poor. Customers must carefully distinguish these details during selection.
Now the clasp. The clasp is the latest style – a butterfly buckle. The new logo is very clearly engraved. On the inside, there are also precious metal marks – AU750, dog head, scale, and crown. The engravings are very well done. Look at the back of the clasp when closed – the Calatrava cross logo – perfectly executed.
If it’s a good gold case, its details will be very close to the original, making you feel less embarrassed when wearing it. This is also the purpose and meaning of modified watches – to let you spend less money and achieve more.
This is the PP 5167R rose gold grenade Aquanaut – customized with 18K gold, developed and upgraded with top‑tier aftermarket parts.
