What is the quality level of the Clean Factory Daytona movement with the Shanghai 4131?

I am CN Watch. I share watch knowledge with you, compare authenticity, disassemble and evaluate, and guide you through the world to avoid getting lost. Let’s take a look at the new Rolex Daytona, which features the 4131 movement developed by Clean Factory and the Shanghai Movement. The high-quality replica of the 4131 movement was jointly developed by Clean Factory and the Shanghai Factory. Clean Factory, according to the most recent information, is the exclusive manufacturer for the Shanghai 4131 movements, which means it has the sole right to use these movements. It is confirmed that the Dandong movement, which watch enthusiasts had speculated about, has no relation to Clean Factory. Let’s not delve into the potential issues between Clean Factory and Dandong. Instead, let’s look at the latest updates on the movement.Daytona watch Rolex.

Comparing the new Daytona, which is equipped with the Shanghai movement 4131, to the original 4131:

When we look at the genuine original products, it is clear that the new Daytona models, which were officially launched by Rolex in the 1265 Series, are a major upgrade from the 1165 Series. The most significant upgrade is the movement, despite the changes to the exterior. The move from the old 4130 to the new movement 4131 is a significant step forward. The new 4131 has a hollow-scale rotor and an improved shock-absorbing system. Two key features are evident when examining the 4131 original movement. The 4131 movement is a better foundation than the 4130. Second, both the power reserve of the 4131 and its functionality are the same as those in the 4130. This ensures consistent performance.

How is the quality of the new Daytona from Clean Factory, equipped with the Shanghai 4131 movement?

Previously, Clean Factory’s high-quality Daytona models from the 1165 series used the Dandong 4130 movement, which became a major selling point. Now, the new Daytona is equipped with the Shanghai 4131 movement. Some watch enthusiasts may question the quality of this high-imitation Shanghai 4131 movement, especially considering the issues with the previous Shanghai 4130 movement. The earlier 4130 movement had several shortcomings, including 1) instability compared to the original, 2) inability to reset the timing function to zero, 3) a rough movement rotor, 4) a winding feel that didn’t match the original, and 5) a noisy automatic rotor, among other problems. The question is whether the new Shanghai 4131 movement has addressed these issues.

Currently, the manufacturers using the Shanghai 4130 movement include APS Factory, ZF Factory, and several others who lack the rights to use the Dandong 4130 movement. Most watch enthusiasts who purchase high-end imitation Daytonas typically choose the Clean Factory, which uses the Dandong 4130 movement. From the N factory to its closure and now to the new Clean Factory-BT factory-N factory, Clean Factory has become the preferred choice. The key advantage of choosing Clean Factory lies in its movement and detail processing. The highly anticipated Clean Factory Daytona 4131 movement is produced in collaboration with the Shanghai factory, but in reality, the production process is largely handled by Clean Factory itself. This includes the grinding, electroplating, scaling, polishing, and assembly of both large and small parts, all of which are carried out independently by Clean Factory.Daytona watch Rolex.

Clean Factory demands a higher level of quality. This is why the replicas of old Daytona models are the most popular on the market. They aim to keep their reputation intact and avoid making any mistakes. The Shanghai 4131 movement is said to have a power reserve of 75 hours, which is more than the 72-hours reserve in the original. To verify the 75-hour claim requires actual testing, since it is unrealistic to expect every movement to achieve a 75-hour power reserve. It is normal to expect small variations in duration, but they can be documented. Both the Dandong 4130 and Shanghai 4130 movements provide a power reserves of around 68-72 hours. This is impressive for a replica high-end movement.Daytona watch Rolex.

From the actual images, we can observe that on the left side is the original Rolex 4131 movement, while the right side shows the Shanghai 4131 movement. When compared, it is clear that the overall structure is restored to about 98%. The rotor’s grinding and the polishing angles on the bottom plate and core bearing are particularly refined, with the details closely matching the original movement. We won’t dive too deeply into the small and intricate components, as they are complex and tiny. For comparison, we focus on the position of the balance wheel on the surface and the scale of the hollow rotor. The “Daytona” engraving on the rotor’s axis is clear and neatly done, whereas the scales on the “CHRONOMETER” and “PERPETUAL” areas are slightly less sharp. It’s worth noting that while most of the 1265 series Daytonas feature a solid caseback design,

The movement could be upgraded with a new rotor if it has a transparent back. The entire movement of the transparent case-back model M126506 in ice blue can be seen by the lens. This restoration is considered to be of the highest quality in the market for high-end Daytona copies. In many cases, the level of detail and precision plays a major role in a purchaser’s decision. The replica movement is a great choice when it comes to its integrity. It is the replica of the movement that poses the greatest challenge in the high-end market. This is because mainland factories are still unable to match Swiss movements’ quality, and manufacturers need time to perfect their designs. The Clean Factory 4131 movement is a good choice for now.
