BT Factory (better) Rolex Daytona detail review
BT Factory (better) Rolex Daytona's bezel opening width is 38.5 mm; same as original. Thickness with Doraemon sticker attached is 12.4mm, 12.3mm with sticker removed; This thickness is the same as the original. Therefore, there is no need to do additional glass precipitation; The glass is already collapsed when leaving the factory and this height is the same as the original. Thus, the total thickness of the watch is 12.3 mm, which is exactly the same.


There is no need to say much about the chronograph function of the BT Factory (better) Rolex Daytona; It has the same 4130 movement inside as Clean and N Factory. In terms of all functions, the Rolex Daytona is the same. The mechanism is single stage; When you pull the crown, you directly set the time, and when you turn it clockwise, the hour and minute hands move clockwise. As for the 7750 movement, it can be made single-stage in the market, but it is turned in the opposite direction. In other words, you can distinguish whether it is a 4130 movement or not in terms of its setting; Also, the feeling in your hand while setting it up is a little lighter.
The movement inside is the self-made caliber 4130, which we all know very well. These come from the same factory as N Factory's and are the same in terms of stability. There is only one difference; where? There is a slight difference in the engraved inscriptions on the mechanism. The N factory prints the Rolex logo on the movement before it leaves the factory, and this text is a little shallower. BT Factory, on the other hand, uses the post-carving method; The mechanism is taken blank with no inscriptions on it, and BT Factory engraves these inscriptions later. That's why his writings appear deeper and a little thicker. This is where it becomes the same as Clean, but slightly different from N Factory; everything else is the same. This mechanism is extremely stable and durable. N introduced this three years ago and the return to service rate is really low; It can compete with the current ETA 7750. Timekeeping is stable and the margin of error is small; really good!

As for the BT Factory Rolex dial, there is no color difference on this white dial; The size of the three small secondary dials on it is also the same as the original. The lume filling on the dial surface matches the original, and the central axis is also filled. It doesn't have a gap in the middle; The tips of the hour and minute hands are also more pointed and a little fuller, in line with the original. It is not like the piece of tin (i.e. thinner, with very rough edges and lots of burrs) like in the N factory. There are no such burrs in BT. Therefore, it is much better than N Factory in terms of quality control across the dial. The edge of the glass is also more transparent; There is no longer a ring-shaped white edge like before.


He also carefully compared all the details: the brushed and polished workmanship of the bracelet, the large opening of the clasp, the chamfering on the Rolex Daytona and the buckle coding. BT Factory has actually found the manufacturing factory of AR in all these details; Therefore, this bracelet is the same as that of the AR and there is no need to further upgrade that AR steel bracelet anymore.


Which of the BT Factory, Clean and N Factory Rolex Daytonas is worth buying?
Summary: The BT Factory (better) Rolex Daytona deserves recognition. Compared to N Factory and Clean, his opinion is that on the Daytona with a black dial and ceramic bezel, the silver-gray color on the outer ring of BT Factory's three sub-dials is better done and does not reflect light. But Clean is more successful on the white dial; Clean is also better in terms of quality control. There is no other difference except that the glass cutting angle is different and BT Factory is slightly better in transparency. The choice between these three factories is up to you. As of now, though, Clean panda likes Daytona better; After all, it is a factory that tries to specialize in depth in Rolex replicas. The downside is that it constantly runs out of stock; So much so that some sellers do not like to sell it. Also, the product options are not as many as N Factory. Currently the order is as follows: If Clean is available, choose C, otherwise choose N or BT. I hope this article will be useful to you. We will share more detailed parts disassembly, real shot review and real-replica comparison in the future.
