Here are the essential features of this custom modified Modified Patek Philippe Aquanaut 5167R:
1. Model & Customization
- Model: Patek Philippe 5167R rose gold Aquanaut (“Grenade”)
- Unique feature: The bezel is inlaid with diamonds – this is not from the original (genuine PP 5167R does not have diamond bezels). This is a DIY customization for a more luxurious look.
2. Material & Weight
- Case and buckle made from real precious metal AU750 18K rose gold
- Total weight: 122.9 grams – matches the genuine weight
- Developed using CNC original data to achieve correct material, color, and weight
3. Dial, Hands & Calendar – “Wearing Accessories”
- Developed with original data, customized after order
- Key differences from ordinary market dials:
- Lume filling: Correct version is white – market versions often have yellow lume (incorrect)
- Scale (hour marker) 3D effect: Very full
- Hands: Three‑dimensional; central axis matches genuine; no burrs from side view
- Calendar: Ink is very three‑dimensional (matches genuine printing process). Market calendars are very thin, flat, lacking 3D effect.
4. Thickness & Movement
- The 5167R is a three‑hand, very thin watch – thickness only 8.1 mm, matching genuine
- Movement: Moulded integrated calibre 324 (clone)
- Truly non‑regulated (no card) structure – balance wheel has counterweights around it (no additional speed adjuster). Most market 324 movements have a card regulator – this one does not.
- This “non‑regulated balance wheel with counterweights” process normally only appears in genuine watches.
- Bridge engravings: Gilded inscription – double P logo, Patek Philippe logo, full spelling – all very, very clear
- Automatic rotor: Upgraded to 18K gold automatic rotor – matches genuine material and color
- Claim: This modified 324 movement is currently the closest on the market to the genuine 324 movement
5. Case & Bezel Craftsmanship
- Case developed from CNC original data
- Bezel edges and corners: Very delicate treatment. The Aquanaut bezel is not a pure circle – it has a specific corner. Some factories make the “head” (lug area) too long – incorrect.
- Polishing & chamfering: Side polishing and chamfering match the genuine
- Brushed finish: Very delicate feeling
6. Caseback & Precious Metal Hallmarks
- Engravings on bottom cover: Scales, dog head, PVC (or similar), 750 mark – all chiseled by craftsmen (hand‑engraved)
7. Buckle / Clasp
- Calatrava cross mark on the button/buckle – very, very clearly engraved
- This craftsmanship is comparable to genuine gold case finishing
8. Upgrade Options (If Budget Allows)
- Can use genuine original dial, hands, calendar
- Can use genuine original 324 movement
- Recommended for those with sufficient budget who pursue perfection

This modified PP 5167R with diamond bezel targets buyers who want the prestige of a Patek Aquanaut but with added diamond luxury – a combination not offered by Patek itself. The underlying craftsmanship (real gold, correct weight, non‑regulated clone movement, 3D calendar, white lume, engraved bridges, gold rotor) is at the very top of the replica market. The diamond bezel is a matter of personal taste.
Bozwatch’s emphasis on the non‑regulated balance wheel is particularly noteworthy – this is a technical marker that separates high‑end clone movements from ordinary ones. The white vs. yellow lume comparison is another simple but effective quality check. For collectors who accept that this is a custom replica (not a genuine Patek) and who want both the Nautilus design and diamond sparkle, this watch represents a well‑executed option. As always, buyers should verify gold purity, understand that plating is not used here (solid gold), and be prepared for the legal and ethical gray area of modified watches.
Hello everyone, this is Bozwatch.
Every watch is a work of art, and I’m a fan of them. I also hope that all watch lovers can avoid pitfalls and find their own “Bole” (a discerning patron).
According to the requests of fans, they wanted to know about the best modified and upgraded Patek Philippe 5167R rose gold grenade on the market, and they asked me to make a video to authenticate it. Today, I paid out of my own pocket to buy such a watch from a merchant.
This watch is developed with CNC original data to make a PP 5167R gold grenade. But this gold grenade is different from the common grenade on the market – its bezel is set with diamonds. In fact, the original PP gold grenade doesn’t have diamond inlays. But modified watches can be customized and DIYed. Of course, through modification, upgrading, and customization, you can achieve a very nice and perfect effect.
When it comes to gold watches, like this one, its case and buckle are made of real precious metal – AU750 18K rose gold. It restores the original weight, color, and material. As usual, let’s weigh it together. Let’s see how much the entire watch weighs. The scale reads 122.9 grams. This weight is the same as the original. That is to say, through CNC original data development, we can achieve the correct weight and the exact same material.
For this watch, its surface accessories are developed with original data and customized after the order. Some of you may not understand – what does “aftermarket accessories” mean? Aftermarket accessories are highly faithful replicas based on the original dial – the dial color, the sunburst radial lines under light, and the fonts. For example, the luminous fill on the hour markers should be white. But many dials on the market have yellowish luminous fill – that is clearly incorrect.
From the side, you can see that the three‑dimensionality of the hour markers is very full. The central axis of the hands is completely consistent with the genuine. Looking at the hands from the side, there are no burrs at all. See? These are three‑dimensional hands.
Now look at the date wheel. The ink is very three‑dimensional – this is completely comparable to the original printing process. The original has such three‑dimensional ink. But most date wheels on the market are very thin, very flat, and cannot achieve this level of depth.
This watch is a three‑hand watch – very thin. It is also a sporty style from Patek Philippe. You can see its thickness is only 8.1 mm. How do we achieve the same thickness as the original? We use a molded, one‑piece integrated Caliber 324 movement.
Let me show you the structure of this movement. Before we play with this product, we need to know its movement model and its functions. This is a true free‑sprung (non‑caliber) movement. Most 324 movements on the market have a regulator (a traditional index adjustment). But this one doesn’t. The balance wheel has counterweights around it. This free‑sprung, weightless balance wheel process only appears in genuine watches. But through our modification, customization, and upgrade, we can achieve a movement with the exact same structure.
On the movement’s bridges, there are gilded engravings – whether it’s the double‑P logo, the Patek Philippe logo, or the full spelling. You can see that the engravings are very, very clear. The rotor has also been upgraded to an 18K gold automatic rotor, which restores the original material and color.
It is said that this modified 324 movement is currently the closest on the market to the genuine 324 movement. The workmanship of this modified movement is very nice – excellent.
If you have special needs – for this gold Nautilus, if you want to pursue perfection – you can also use a genuine original dial, hands, date wheel, and even a genuine 324 movement. There’s no problem. Of course, if your budget is sufficient – very sufficient – then I suggest you choose that path.
Now, the case. This grenade case is made by us based on CNC original data. Look at the bezel – you can see its edges and corners. This treatment is very, very delicate. The bezel is not a perfect circle – the original has distinct facets here. The shape is just right. Some gold case factories make the case too long or too rounded – that’s completely different from the original. The polished sides and chamfered edges match the genuine. The brushing on the sides is also very fine.
Including the precious metal engravings on the caseback – the scale, the dog head, the crown, and the 750 mark – all are hand‑chiseled by our craftsmen. Also the clasp craftsmanship – the Calatrava cross on the clasp is very, very clearly engraved. This level of craftsmanship can compare to the original gold case process.
There are many gold case factories on the market. Before you choose a product like this, you must first understand it. Once you have a clear understanding, then you can enjoy it.
