Summary of Key Points about the Modified Patek Philippe Aquanaut (Model 5261R “Smiley Face” – Multi‑Function Rose Gold)
Based on the latest video transcript (focusing on the Patek Philippe Aquanaut 5261R Rose Gold “Smiley Face”), here are the essential features of this top‑tier modified multi‑function watch.
1. Model & Nickname
- Model: Patek Philippe Aquanaut 5261R – rose gold, commonly called the “Smiley Face”
- A multi‑function grenade (Aquanaut) with several complications
2. Material & Weight
- Case and buckle made from real 18K rose gold (precious metal) using CNC original data
- Total weight: 129.4 grams (approx. 130g) – exactly matches the genuine
- Market products are mostly steel cases with electroplating, weighing only 80‑90g – incorrect. Using real precious metal avoids the weight tell.
3. Movement & Functions
- Uses a 330 movement that achieves all multi‑functions:
- 6 o’clock – date function
- 9 o’clock – month function
- 3 o’clock – day‑of‑week function
- 12 o’clock – moon phase function
- All functions can be synchronized with the original and are fully realized; adjusted via side buttons – completely consistent with genuine
4. Dial, Hands & Strap
- Surface accessories (dial, hands, strap) customized based on original data
- Dial color: “Smog blue” – high‑fidelity reproduction of genuine blue dial (color, sunburst radial pattern, fonts) – very close
- Flaws are very, very small as long as not sent to professional testing
5. Thickness
- The Aquanaut is relatively thin; the 330 movement perfectly achieves the same thickness as the original
6. Back of Movement – Rotor
- Automatic rotor is a custom‑made genuine 18K gold rotor (real precious metal)
- Restores material, color, weight, and winding efficiency – superior to market movements that use copper rotors
7. Gold Case Craftsmanship – Critical Details
When playing with a gold watch, these details are very important:
- Brushing – delicate?
- Case shape – correct?
- Edges and corners – properly treated?
- Crown length – correct?
- Chamfer grinding – well executed?
- Buyers must carefully distinguish good from bad during selection
8. Buckle & Engravings
- Calatrava logo – engraved very, very deep
- Inside the buckle – full Patek Philippe spelling – very, very fine
- Back of buckle – dog head, scale, AU750 mark, PP mark – all very delicate
- Caseback – precious metal engravings (dog head, AU750, scale, PP mark) – must be properly executed
- These are the craftsmanship details a good gold case product needs

Concluding Comment
This video focuses on the Patek Philippe Aquanaut 5261R “Smiley Face” – a rose gold, multi‑function Aquanaut with date, month, day, and moon phase complications. The genuine secondary market price is very high. The modified version uses real 18K rose gold (129.4g, matching genuine) and a functional 330 clone movement that correctly delivers all four complications, adjustable via side buttons exactly like the original.
Strengths:
- Real 18K rose gold – correct weight (129.4g) vs. cheap steel electroplated versions (80‑90g). Weight is a critical tell.
- Full multi‑function movement – date, month, day, moon phase all work and are synchronized with the original. The 330 movement achieves the correct thickness (thin, like the genuine Aquanaut).
- High‑quality dial – “smog blue” with correct sunburst radial pattern and fonts, developed from original data.
- 18K gold rotor – restores correct material, color, weight, and winding efficiency (unlike copper rotors).
- Gold case craftsmanship – attention to brushing, case shape, edges/corners, crown length, chamfer grinding.
- Deep, clear engravings – Calatrava logo, inside buckle spelling, caseback and buckle hallmarks (dog head, AU750, scale, PP mark) – all signs of a good gold case.
Final verdict: The modified PP 5261R “Smiley Face” is for collectors who want a rose gold Aquanaut with full multi‑function complications – a watch that in genuine form is rare and expensive. The use of real 18K rose gold ensures correct weight (129.4g), avoiding the “steel electroplate” tell. The functional 330 clone movement delivers date, month, day, and moon phase with correct thickness. The dial color and finishing are high‑quality reproductions. The gold case and buckle details (brushing, chamfering, deep engravings, 18K rotor) meet high standards. While the movement is not genuine, it is a significant step up from basic clones. For the buyer with a substantial budget who wants a convincing, functional multi‑function Aquanaut, this is a strong contender. As always, independent verification of gold purity (XRF) and movement functionality is recommended. Bozwatch’s emphasis on weight, case finishing details, and the 18K rotor provides a useful checklist. This is the “spend less, wear a full‑function rose gold Aquanaut” proposition.
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 watch enthusiasts can avoid pitfalls and find my own “Bole” (discerning patron).
According to fans’ requests, they wanted to know about the best modified and upgraded Patek Philippe multi‑function grenade currently on the market. They asked me to share how to play with the PP multi‑function grenade. Well, today it’s here.
This watch is the Patek Philippe Aquanaut 5261R Rose Gold Grenade – we commonly call it the “Smiley Face.” This watch is a gold watch made of 18K precious metal.
As always, before we play with this precious metal gold watch, we must first solve the issues of material, color, and weight. This watch is made using CNC original data and real precious metal – 18K rose gold – for its case and buckle. Using 18K rose gold faithfully restores the original material, weight, and color.
Let’s weigh it together, as usual. How much does the entire watch weigh? You can see on the scale – 129.4 grams (about 130 grams). Most products like this on the market are steel cases with electroplating – weighing only 80‑90 grams. If you don’t use real precious metal and instead play with steel and electroplated materials, someone might weigh your watch and realize it’s not correct.
This watch is a multi‑function grenade. It uses a 330 movement that achieves all its functions. What functions?
- 6 o’clock – date function
- 9 o’clock – month function
- 3 o’clock – day‑of‑week function
- 12 o’clock – moon phase function
All these functions can be synchronized with the original and are fully realized. They are adjusted through the side buttons – completely consistent with the original.
The surface accessories – dial, hands, and strap – are all customized based on original data. This blue is called “smog blue.” It is a high‑fidelity reproduction of the genuine blue dial – the color, sunburst radial pattern, and fonts. It’s very close. That is to say, as long as you don’t send it to a professional agency for testing, the flaws are very, very small.
The Aquanaut is actually relatively thin. Our watch uses a 330 movement, which perfectly achieves the same thickness as the original.
Look at the back of the movement. The automatic rotor on the back is a custom‑made genuine 18K gold rotor. Compared to movements on the market where the rotor is made of copper, our watch uses real precious metal – restoring its material, color, weight, and winding efficiency.
When we play with this gold watch, the craftsmanship of its gold case is very, very important. Is the brushing delicate? Is the case shape correct? The treatment of edges and corners, the length of the crown, the chamfer grinding – during selection, you must carefully distinguish.
The buckle is very finely made. The Calatrava logo is engraved very, very deep. Open the buckle – the engraving inside, like the full Patek Philippe spelling, is also very, very fine. On the back – whether it’s the dog head, the scale, the AU750 mark, or the PP mark – all are very, very delicate. That’s the craftsmanship a good gold case product needs to have. There are many gold case factories on the market – when choosing, you must carefully distinguish.
Including the caseback – the precious metal engravings – dog head, AU750, scale, and PP mark – all need to be properly executed.
This is a simple watch sharing of the PP 5261R multi‑function grenade. Before customers choose this watch, they must first understand it. Once you understand it clearly, then you can enjoy it.
