Clean Daytona Shanghai 4131 Mechanical Case and Dial Workmanship

The Rolex Daytona 4131 model is produced by Clean Factory with a solid stainless steel case, standard case 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.

Comparison of the Shanghai 4131 movement used in the Clean new Daytona and the original 4131 movement:

First of all, we can learn this from the original product: At this stage, the models starting with the newest Daytona-1265 series that Rolex has officially launched are the renewed Daytona models. These are improvements made over the models starting with the 1165 series. Apart from the changes and adjustments in appearance, the main thing is the upgrade on the mechanism side. By upgrading the 4130 mechanism (rotor with hollowed out markings in 4131, added escapement system, added shock absorber mechanism) the 4131 mechanism was created. Based on the original mechanism, we can understand two things. First: the conversion of caliber 4130 into a new movement proves that the basis of the old caliber 4130 is extremely flawless. Second: There is no change in the power reserve and functions of the caliber 4131 and the caliber 4130.

How is the quality of the Clean new Daytona fully equipped with the Shanghai 4131 movement?

In the old 1165 series high quality replica Daytona models, Clean official site always used the Dandong 4130 movement, and this turned out to be a great sales advantage. Currently, all new Daytona models use the Shanghai 4131 movement; Some watch-friendly people question what the quality of the high-quality replica Shanghai 4131 movement really is like. The root of this problem lies in the previous Shanghai 4130 movement. The old Shanghai 4130 movement had the following problems: 1: The stability could not reach the effect of the original. 2: Chronograph function could not return to zero. 3: The rotor workmanship of the mechanism was rough. 4: The installation feeling could not match the original. 5: The automatic rotor was noisy. Negative problems like these were coming one after another. So, does this Shanghai 4131 movement also have the above problems?

Factories currently using the Shanghai 4130 movement: APS Factory-ZF Factory and some factories that do not have the right to use the Dandong 4130 movement. The majority of watch friends who buy a replica Daytona prefer Clean; These use the Dandong 4130 movement. This continuity continued from N Factory to the closure of N Factory and from there to today's Clean-BT Factory-new N Factory. The biggest advantage of choosing Clean is the mechanism and detail workmanship. It is inevitable that the Clean Daytona 4131 movement, which everyone is curious about, is a Shanghai factory product. Looking at the real situation, we can understand this: Currently, this movement under the name Shanghai 4131 seems to have been completed as a result of joint production. But it's not like that; The processing, plating, markings, polishing, and all parts of the mechanism, large and small, were completed independently by Clean.

Clean is even more meticulous about quality; After all, since Clean is the best seller of old Daytona models in the entire replica market, of course he won't shoot himself in the foot. It was also announced that this Shanghai 4131 movement has a power reserve of 75 hours; whereas the original product still stores 72 hours of power. However, watch lovers, take the 72-hour power reserve as basis; We need to base the 75-hour test issue on actual evidence. In fact, no mechanism can keep 75 hours with 100% accuracy; Even though there is a difference of a few hours, there is still a basis to prove it. Current 4130 movements, whether Dandong or Shanghai, are also around 68 to 72 hours; It is extremely good that a high-quality replica mechanism can even reach this data.

As can be seen from the real shot photos, the part on the left is the Rolex original 4131 movement, and the part on the right is the Shanghai 4131 movement. By comparison, the entire structure is approximately 98 percent reproduced; The workmanship of the rotor and the polishing angles of the lower bridge have all been done with precision, and the visible detail work has more or less reproduced the original mechanism. Since the large and small parts are very small and complex, we will not dwell on them. We will only compare the balance wheel position on the surface with the marked dial surface of the hollowed-out rotor as reference. The Daytona lettering on the rotor shaft is clear and neat. The signs in the CHRONOMETER and PERPETUAL sections are not that clear; In fairness, this is despite the fact that most of the 1265 series Daytona models have a closed-back design.

If there was a transparent back mechanism, a modification upgrade could be made if an equivalent level rotor became available in the future; As a matter of fact, in the new transparent backed ice blue dial m126506 model, the entire mechanism can be observed through the glass. This requires the highest, ceiling-level reproduction precision in replica Daytona replica craftsmanship. As meticulousness increases, this often determines whether watch friends will buy it or not. Still, it is an extremely flawless mechanism in terms of the integrity of the mechanism replica; Ultimately, the most difficult technique to overcome in the replica market is the mechanism replica issue. Mainland movement factories have long been unable to achieve the same quality as Swiss movements; This requires giving factories time. As of now, buying the Clean 4131 movement is not a wrong choice.

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