| Crown | Very 3D; two dots below; oval bottom; five points separated on top – correct for Day‑Date |
| Bracelet links | Each link exactly the same size; each link equipped with ceramic tubes (like genuine) – prevents loosening over time (old DD without ceramic tubes becomes loose and not straight) – this is an important quality standard for gold cases |

| Finishing | Brushed areas very delicate; polished surfaces properly treated |

- Performance: Very stable, daily error within ±5 seconds
- With this movement, unless you open the case back or send to a professional lab, no flaws will be detected when wearing
7. Overall Quality Statement
- Custom‑made with 18K solid gold, CVD diamonds, and genuine Tudor movement
- Case, bracelet, and finishing all based on original data
- Represents the current best modified 2839869 Ruby on the market
This modified 2839869 Ruby is arguably the most sophisticated replica reviewed so far – not because of the gold or diamonds, but because of the genuine Tudor movement. For collectors who want the look of a full‑gold ruby‑marker Day‑Date with reliable Swiss movement performance, this build offers an unusual value proposition: real gold + real Swiss movement + high‑quality diamond setting. The inclusion of ceramic tubes in the bracelet addresses a long‑standing weakness of vintage‑style Day‑Date bracelets. Bozhong’s checklist – case curvature, crown 3D, borderless inlay, ceramic tubes, hallmarks – is excellent guidance for anyone evaluating high‑end gold replicas. However, transparency remains key: this is a custom build using real precious metals and a genuine Tudor movement, assembled into a non‑genuine Rolex case and dial. For the right buyer (who understands and accepts these terms), it represents the peak of the modified watch category.
Hello everyone, this is Bozwatch Reviews.
Every watch is a work of art, a testament to time, and I am a fanatic believer in 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 know the best modified watch currently on the market – the 28398 6&9 Ruby. They asked me to make a video with them to authenticate it. Well, today it’s here.
This watch is the 28398 6&9 Ruby – a top‑of‑the‑line modified configuration. It is custom‑made from 18K gold. Everything you see in gold color – its bezel, its middle case, its crown, its strap and buckle – are all made of real precious metal, AU750 18K solid gold.
For custom precious metal products like this, they can achieve the same weight as the original. Let’s weigh it and see how much the entire watch weighs. You can see on the scale that this watch is 206.8 grams. This weight is exactly the same as the genuine article.
What makes this watch very famous is the 6 o’clock and 9 o’clock positions – they use red gemstones (rubies) as hour markers. All other markers are diamonds, with diamonds used as indices. This watch is really, really shiny, and its appearance is truly superb.
This watch is a diamond‑set watch. Our accessories – such as the dial, the bezel, and the diamonds on them – are made using laboratory‑grown CVD diamonds. When set like this, to the naked eye they are almost the same as natural diamonds. However, you would need to go to a professional institution to distinguish them, mainly due to the price difference between lab‑grown and natural diamonds.
The diamond setting on our watch – you can see that on the dial, the diamonds are set very, very tightly. Their arrangement is hand‑set one by one. Including the baton markers, the diamond setting is very good. The diamond setting on the outer ring is even better – it uses a borderless setting technique with no gaps between the diamonds. This is the standard for high‑quality diamond setting. A good diamond setting can reach the same level as the genuine.
This watch was customized after being developed with CNC original data. Like this watch – the maker found a genuine original watch, placed it in a 3D CNC machine, scanned its data, then through machine grinding, and later master craftsmen performed manual polishing, brushing, sanding, and finishing.
You can see that the brushed areas are very delicate, including the polished surface treatment. You can see that a Day‑Date watch is not completely flat – see? It has a slight curvature. This slight curvature can be made completely consistent with the original.
Now look at the crown – the crown treatment is very three‑dimensional. See? It has two dots below, and the top is oval. The top is divided into five points. The crown craftsmanship is also completely consistent with the genuine.
For this type of watch, you can see that the size of each link is the same. And every link is equipped with a ceramic tube exactly like the original. It is said that after installing the ceramic tube, your watch will be very sturdy and straight. On older style Day‑Date watches without ceramic tubes, after a period of use the bracelet becomes loose – very loose and not straight. This is an important standard for distinguishing good gold case products from bad ones.
Another point – for these gold watches, the three‑dimensionality of the crowns and these details are very important. The crown is oval at the bottom with five points on top – very three‑dimensional. Also, look at the precious metal engravings inside. Let me show you the engravings – they are very, very clear. You won’t see this level of craftsmanship in other stores. Including the dog head, scales, and AU750 – see? This is what a good gold product should have. The details of the craftsmanship, including the engravings on the caseback – like the AU750, the scales, the crown, and the dog head here – all the precious metal engravings can be made to the same level as the original. The brushed and polished finishes are treated very, very well.
This Day‑Date watch has both day and date functions. The day and date will jump forward at 12 o’clock at night. Currently, this watch is equipped with an original Tudor 2834 movement for the upgrade. So why use a Tudor movement? As everyone knows, Tudor is Rolex’s sister brand. Using this movement, it can achieve the same calendar function as the original, including the smooth jump feature around midnight. It runs very stably, with a daily error within five seconds.
As long as you don’t open the caseback or send it to a professional agency for testing, you can wear it out – there will be no flaws.
This is the 28398 6&9 Ruby – custom‑made with 18K solid gold and set with lab‑grown diamonds. This is a watch sharing of this piece.
