Concluding Comment
This video covers the Rolex Day-Date 228398 T‑diamond black ice sugar – a full 18K gold watch with a T‑shaped diamond bezel and black sunburst dial. The modified version uses real 18K gold for the case and strap, achieving the correct weight of 205.8 grams. The bezel diamonds are CVD lab‑grown set with a borderless technique (no gaps). The dial, hands, and thick‑fill date are high‑quality aftermarket parts. Because the Day-Date has a solid caseback, the movement is not visible – it uses an original genuine Tudor 2834 movement (Rolex’s sub‑brand), which reliably delivers the day/date jump at midnight with ±5 sec/day accuracy. The case finishing (brushing, polishing, hand‑chiseled engravings), straight strap with ceramic tubes in each link, 3D crown, and clear hallmarks (AU750, dog head, scale) are executed to a high standard.
Strengths:
- Real 18K gold – correct weight (205.8g), material, and color.
- T‑diamond bezel – borderless CVD diamond setting, no gaps.
- Solid caseback advantage – movement hidden, eliminating that tell.
- Genuine Tudor 2834 movement – stable, accurate (±5 sec), correct day/date jump.
- High‑quality dial/hands/date – full sunburst, 3D hands, thick date.
- Detailed gold case finishing – ceramic tubes in strap, 3D crown, hand‑chiseled engravings.
Final verdict: The modified 228398 T‑diamond black ice sugar is an excellent choice for collectors who want a full gold Day-Date with a diamond bezel and the reliability of a genuine Swiss movement (Tudor 2834). The real gold weight, borderless diamond setting, and solid caseback make it very convincing. For those with the budget who understand the trade‑offs, this watch offers a “spend less, enjoy a top‑tier black ice” experience. As always, independent verification of gold purity (XRF) and movement authenticity is recommended. Bozwatch’s emphasis on weight, borderless setting, ceramic tubes, and hand‑chiseled engravings provides a solid quality checklist. This is a standout piece for Day‑Date enthusiasts.
Hello everyone, this is Bozwatch Reviews.
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 their own “Bole” (discerning patron).
Due to fan requests, they asked me to film a modified black ice watch. They wanted to know how to play with the black ice sugar. Well, today it’s here.
This watch is model 228398 – a T‑diamond bezel black ice sugar. It’s the top product in the black ice lineup. Black ice actually comes in three styles: fluted bezel, round diamonds, and T‑shaped diamonds. It mainly depends on personal preference. Of course, the T‑diamond black ice sugar has the highest secondary market price – the most expensive.
This watch is developed based on original CNC data and is a gold watch made of real precious metal. Its case, crown, caseback, strap, and buckle are all made of real precious metal – AU750 18K gold.
As usual, let’s weigh it together. How much does the entire watch weigh? You can see on the scale – 205.8 grams. This weight is exactly the same as the original. Gold watches customized with precious metal can perfectly restore the original weight, color, and texture – something watches made of other materials can never achieve. Some black ice watches on the market use electroplating or gold‑plating, but their colors always have some color difference compared to precious metal. If you have enough budget, I recommend using real precious metal to make this watch.
The surface accessories – dial, hands, bezel, date wheel, etc. – are all customized based on original data. For a good black ice product, the dial’s sunburst pattern under light is very full – a texture that other accessories cannot achieve.
The diamonds on the bezel echo the diamonds on the dial. These diamonds are CVD lab‑grown cultured diamonds, set using a borderless setting technique – no gaps at all. Each diamond is the same size and distinct. This craftsmanship compares to the original.
The hands are three‑dimensional with no burrs – very delicate. The date wheel is a thick‑fill date that fills the entire window. Its spacing and centering are all correct.
For this watch – because the black ice Day‑Date has a solid caseback – as long as we solve the material, weight, and surface accessory issues, without opening the caseback, the flaws are very, very small.
The movement used is also particular. It uses an original genuine Tudor 2834 movement. Why use a genuine Tudor 2834? As we all know, Tudor is a sub‑brand of Rolex. Using this movement achieves an important function: around 12 o’clock at night, the day and date jump simultaneously. That’s a key function. The movement is very stable, with a daily error within five seconds.
When choosing this kind of gold watch, pay attention to details and craftsmanship. First, check the delicacy of the brushing and polishing – the brushing, polished surfaces, and the tight fit between the strap and case head (no gaps). The caseback brushing and precious metal engravings are also very important. See? These engravings are all hand‑chiseled by our craftsmen – very precise.
When choosing a Day‑Date like the black ice, note that newer Day‑Date models have very straight straps – not loose at all – because each link is equipped with a ceramic tube.
Look at the crown – its craftsmanship is very three‑dimensional and vivid, consistent with the original. Including the buckle and the engraved precious metal lettering – the Rolex engraving, English letters, AU750, dog head, and scale – all hand‑chiseled, very clear and accurate.
At this level of modification, as long as you can wear it out, this real precious metal black ice sugar will help you spend less money to achieve big results.
