Bokey TimeHello everyone, this is Bokey Watch Industry. It goes without saying how popular the Rolex Daytona is. Ever since the N factory, in collaboration with the Dandong movement factory, developed the 4130 movement in earlier years, the Daytona has not only improved in terms of simulation accuracy but also taken a step up in price. After the N factory ran into trouble, factories like C, BT, and King continued to launch various models of the Daytona equipped with the Dandong 4130 movement.
Nowadays, seeing how popular the 4130 movement is, other movement factories have also started planning to launch their own versions of the 4130 movement. For example, the newly released Shanghai 4130 movement this year is used in the Daytona models from factories such as APS, ZF, and QF. So, which one is better: the Shanghai 4130 movement or the Dandong 4130 movement?
First of all, in terms of details such as the craftsmanship and materials of the Daytona, the differences between major factories are basically very small, so we will not discuss them in too much detail. It is not meaningful to use macro lenses to shoot and magnify dozens of times to make overly critical evaluations of the Daytona. The imitation difficulty of parts like the case, strap, and dial is not high. As long as one is willing to spend more money, it is completely feasible to find good accessory factories for customization.
First, let’s take a look at the appearance of the Dandong 4130 and Shanghai 4130 movements. Overall, the differences are not significant. Both are replicated by referring to the genuine 4130 movement, with the same structure, jewel positions, and gear positions. The main difference lies in the position of the regulator (hairspring position). The Shanghai 4130 has added a fake regulator-free stud at the bottom to make it closer to the appearance of the original. The regulator of the Dandong 4130 movement is located on the right side as shown in the picture. It can be seen that the Shanghai 4130 is mainly designed to meet the psychological needs of some watch enthusiasts with obsessive-compulsive disorder. Since the Daytona has a closed-back design, the presence or absence of this fake stud doesn’t really matter. On the contrary, the Dandong 4130 movement is more convenient to operate when adjusting the timekeeping error.
In addition, in terms of stability, the Dandong 4130 movement has withstood years of market testing, and its quality and stability are indeed commendable. The Shanghai 4130 movement was released this year, and its stability needs further observation.
Finally, the Shanghai 4130 movement has an advantage in its 72-hour power reserve, which is on par with the genuine product. Watch enthusiasts who like the Daytona can make a comprehensive comparison and choice based on their own needs. Now, more and more factories are producing the 4130 Daytona, and it is believed that with the intensifying competition, the price will become more affordable in the future.
