Hello everyone, I am Bokey Watch Industry. This authenticity comparison brings a review of the VS factory’s weighted gray rubber Daytona compared to the original genuine product. The official model is: Rolex Cosmograph Daytona series m126519ln-0006 watch. This genuine product is made of 18K white gold, while the VS factory uses a weighting method of 904L steel wrapped with tungsten steel to achieve the same weight as the original watch head. At the same time, gold plating can be added later, and there will be no problems of peeling or chipping. Now let’s see what is the gap between the VS factory’s weighted Daytona Dandong 4131 and the original?

The left side of the above picture is the original version, and the right side is the weighted version of VS factory. The embroidery of the two is almost indistinguishable. The picture below is a comparison of their weights. It can be seen that the VS factory is only 1 gram lighter than the original. This is also very important. For other versions on the market, patches are added to the bottom cover just to make up the gram number, resulting in an overweight watch head. It is very uncomfortable to be top-heavy. Another kind is to make weights, and it feels light and not in line with the original version when worn.

The weight difference between the two watches mainly lies in the buckle. The material of the original buckle is platinum, while VS factory uses 904L stainless steel, so it is 26 grams lighter than the original. However, compared to other factories that lengthen the strap and thicken the very thin memory metal sheet of the original version to make up the weight, resulting in a non-soft strap. VS factory does not adopt this speculative way of sacrificing the original wearing experience for small gains at the expense of big ones. After all, the whole watch already weighs about 136 grams. When worn on the hand, there is still a certain sense of pressure. There will be no problem of being recognized. After all, he will not weigh your watch with an electronic scale!

In terms of size, let’s first talk about the thickness. The difference between the two is only 0.28 millimeters, a gap that is almost imperceptible. As for the dial diameter, they are the same.

Dial comparison. The color temperature of the two is basically the same. In terms of details in all aspects, whether it is the round polishing of the central axis or the bar nail scale, or the delicate radial pattern of the dial, the VS factory has restored them all.

The engraving on the bezel and the glass have no difference at all.

In terms of movement, the VS factory’s weighted gray rubber Daytona uses the Dandong 4131 movement with higher cost and better stability. 95% of the structural parts of this movement can be interchanged with the original. Including its power reserve, it also has 72 hours like the original. The chronograph function is also synchronized with the original and truly usable.

Comparison of case and buckle details. The overall case shape of the weighted version of VS factory is the same as the original. There is no problem of bloated case body like other weighted versions on the market. It completely follows the original design.


Overall, this VS factory weighted version 4131 grey rubber Daytona is relatively high in detail restoration except that its buckle is 20 grams lighter than the original. Moreover, its price is much lower than other weighted versions on the market. If you are also looking for the ceiling version of the Rolex cement grey rubber Daytona 126519 replica watch, then this VS factory weighted version must be the first choice.
