Development history of Replica 4130 movement – ​​BT Factory Rolex Daytona chocolate dial real shot photos

The Rolex Daytona model is produced by BT Factory with a solid 904L stainless steel case, 40 mm diameter and Dandong 4130 chronograph movement architecture. It is among the most successful 1:1 super clone watch reviews on the market, with its sapphire crystal AR coating glass, original case tolerances and detailed workmanship.

The replica of the skin was actually already at such a good point that there wasn't much room for upgrades; Therefore, being able to resolve the similarity on the mechanism side definitely means a very successful replica product. Last year the market was also quite bad, many watch lovers have heard this; Even large factories such as N, VS and V6 had to stop their operations. Thus, the Daytona with its fully integrated replica 4130 movement was eliminated; It was a shameful model. At that time, some dealers began to release Daytonas that converted the 7750 movement to a single stage and adjusted the thickness to around 12.6 mm, which is the N Factory thickness. Since the Daytona is a closed case back model, as I said before, the two differences between the 7750 movement and the original 4130 movement were the single step in the time setting and the thickness issue; Vendors have also taken care of these two points of difference. Some watch lovers who do not have such high expectations may prefer this modified version; As a result, the watch setting shape and thickness on the outside are at a level that can be confused with N Factory. Of course, some watch friends wait and do not settle for less; Also, at that time, some unscrupulous sellers were selling poor quality as high quality. Towards the end of last year, the N4130 Daytona started to appear on the market again in some color options; Several colors were in stock, including the Panda Daytona, black ceramic Daytona, gray rubber Daytona, ice blue Daytona, and Shawn Yue Daytona. These were actually leaked tracks from N Factory; Released after being exported and reassembled, it was not assembled using original factory workmanship. Since the original factory was closed, the thickness of the assembled model is also slightly larger than the original N Factory, approximately 12.8 mm; The original is 12.6 mm. So far this N4130 Daytona is always on the market; Additionally, a few more models have been added to the color options. There is also a Daytona with a carbon fiber 4130 movement, but its case is not the original factory case.

The above is for watch enthusiasts who produce by converting the 7750 movement into a single stage and reducing its thickness. I don't mean to say these versions are bad, they just aren't the best; If the budget is not enough, naturally it is necessary to settle for less, so this varies from person to person.

Last year, it was rumored that C would release a Daytona with a fully integrated replica 4130 movement, and at the end of the year, this rumor was confirmed; Clean, aka Clean, introduced the Daytona with the 4130 fully integrated replica movement. For now, there are only four color options: black-and-white ceramic Daytona and black-and-white steel Daytona. I also discussed its comparison with the N4130 Daytona as a product in a review article. In terms of parts, C clearly surpasses N; Because BUFF brand was used on the hour and minute hands, which is a manufacturer that deals especially with original hour and minute hands. Then AR Factory's steel bracelet was used in the steel bracelet; It is widely accepted that AR is the best in Rolex steel bracelet replicas. The reason why AR has been able to win the hearts of some people so far is; he uses only the best. Then comes the clean bezel, that is, the C bezel; Clean started with a scaled bezel in the beginning, so naturally it is much better than N and other manufacturers in scaled bezels. In addition, glass precipitation was applied to the glass, and the thickness reached the same level as the original. Recently, another Daytona with a fully integrated replica 4130 movement has appeared on the market; Its name is bETTER Factory, BT Factory for short, haha. Because it was better, it was abbreviated as 'BT', which means 'maniac'.

Joking aside, I went on a bit too much; Now let's get back to our main topic today: the review and evaluation of the BT Factory fully integrated replica 4130 movement Daytona. This is a sister model from the same lineage as the 3K Factory.

bETTER Factory Daytona specification list: Model: 116500, Dimensions: 40 mm × 12.2 mm, Functions: hours, minutes, seconds, chronograph display, Movement: 4130,

Power reserve: 72 hours, Glass: sapphire, Dial: white dial, black dial, Material: 904L steel, Strap: AR Factory steel bracelet, Bezel: platinum film coated ceramic bezel, Lume: Swiss lume paint, Water resistance: 100 meters, Weight: 148 grams

Nine important features of the BT Factory (bETTER Factory) Rolex Daytona:

1. The thickness of the BT Factory Daytona 4130 movement watch is 12.2 mm. Other versions on the market use the 7750 false bridge movement; They thin the movement thickness by pressing the hour-minute hand shaft. Its stability is extremely poor, it cannot reach the same level as the original.

2. 4130 mechanism (former N Dandong factory) is used; The engraved and electroplated inscriptions on the rear bridge are brighter.

3. Original AR Factory is used on the steel bracelet. Additionally, the proportions and dimensions of the buckle have been improved once again.

4. The case is processed by N factory, taking the 2022 newest version as an example; The polished shiny surface size of the case back and the curve of the serrated edge have been updated.

5. The hour and minute hands have been re-improved by Buff factory; three small seconds hands and a large seconds hand, each individually custom-made and with a solid needle barrel; The needle heads have rounded tips like mushrooms.

6. The ceramic bezel Cerachrom has been improved again; While the platinum film coated texts maintain their color, the text thickness has also been updated.

7. The dial is modeled after the 2022 newest version white dial; By blending and processing Swiss ink and Korean ceramics, a pure milky white appearance with a full texture, with no color difference with the original, was achieved. Say goodbye to the blackish 'dead white' color previously seen on the market.

8. Hour markers are engraved one by one with independent CNC, and the edges of each are processed by hand. Swiss lume powder is used for lume and there is no color difference with the original. As a result, the effect closest to the glow appearance of the original is achieved on the market.

9. Fully transparent sapphire is used in the glass, there is no edge appearance. The edges of the glasses currently on the market are rounded, curved and give a thick appearance. Only BT Factory's detail workmanship is the same as the original.

Above was BT Factory's detail teardown review compared to the original. We also reviewed Clean; Watch friends who haven't read it yet can contact me and ask for the link. According to the above comparison, BT Factory has done a really good job; Anyway, the movement is the same Dandong 4130 movement. Compared to C, only the external appearance can be compared. The only point of difference in appearance to me is that the solid center shaft is slightly different from the C; everything else is the same. If the price is the same, I think many watch lovers would want to choose the C; because C is specifically involved in the Rolex business. It is necessary to evaluate the future opinions of watch enthusiasts about this watch as a whole; But there is one point worth mentioning: BT Factory dismantled and made a replica based on the latest 2022 model Daytona, thus offering watch friends a more direct comparison with the newest version. For example, in the previous C, minor errors could occur, such as some watch friends saying 'The dial of the C is too white'; but they are all true to the original. If a replica watch does not even match its appearance, let alone the mechanism, it is not considered a replica anyway. Now let's look at the actual shooting details.

On the back there is a cartoon sticker modeled on Clean, a panda; This is a differentiating point of BT Factory. Now let me show the details of this watch to watch friends.

In replica watches, the work is in the details, they are not afraid to zoom in. Above was the development history of Daytona and the review of Daytona with BT Factory 4130 movement. This version is also a nice option and one of the top-of-the-line Daytonas. Because the 4130 fully integrated replica mechanism is used as the mechanism; There are currently only three manufacturers on the market: one N, one C, and one BT, which we are talking about today. The exterior parts and workmanship are also quite good; It's on the same level as C, after all, it comes from 3K Factory, which is also the top producer of Nautilus.

I hope this article will be useful to you. We will share more detailed disassembly, real shot review and real-replica comparison in the future.
