How do you distinguish between the N Factory 4130 Daytona movement and the 7750 movement?

The Rolex Daytona model is produced by Noob Factory with a solid 904L stainless steel case, 40 mm diameter and 7750 automatic 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.

Movement and Caliber Performance

This didn't change radically until N Factory introduced the brand new Rolex Daytona (a product specially developed together with the movement factory); With this step, they widened the gap between themselves and other factories. First, they overcame the following challenges: A slimmer structure than any 4130 replica produced in the past, fully synchronized with the Cal.4130 movement of the original. So the Daytona replica is finally on par with the original in terms of thickness. It also has exactly the same functions as the original (the converted 7750 can also have all the functions, but it is too thick and does not work stable after conversion; AR's copy Cal.4130 mechanism is not bad in terms of stability, but it cannot fully meet the functions). This time, the specially designed mechanism of the N Factory factory is truly perfect.

Currently, the N Factory Daytona is available in both 7750 and 4130 caliber versions. I definitely do not recommend the 7750 movement; Its stability is very poor, it breaks down frequently and is even much less stable than the JF Factory Daytona's 7750 chronograph movement. On the other hand, I highly recommend the N Factory Daytona 4130 movement; It's definitely worth buying, it has essentially no flaws, and the price is reasonable. Most importantly, its quality and stability are extremely good, its power is high and its failure rate is very low. Currently, among the Daytona options with the 4130 movement, there are models such as panda Daytona, steel Daytona, rose gold Daytona, gray Daytona; They all use 904L steel and have both steel bracelet and rubber strap options.

N Rolex Daytona's special 4130 movement is 40 mm in diameter. The old N Daytona and JF Daytona were 1mm thicker than the original factory size; The new N Rolex Daytona is the same thickness as the original, that is, 12.6 mm.

Dial and Hand Details

In terms of the movement, there are no longer any visible flaws in terms of thickness or chronograph function; They did the job very well in terms of quality. According to sellers, only 3 of the N Factory Daytonas sold in more than a year since their launch have come in for repair; It can be said that a miracle has been created in chronograph watches.

KIF shock absorbers are generally not used in specially produced 4130 movements due to cost. However, this is the first time that N has used a special version KIF, a high-end shock absorber of this kind, in a replica movement. The three-layer base plate is completely machined to the original factory standard, from chamfers to sun pattern, and is very close to the original in appearance. So how do you easily distinguish them? Change the pitch and listen to the sound of the rotor! It uses the old Daytona 7750 chronograph movement, and the 7750 is wound unidirectionally; All you have to do is hold the watch in your hand and shake it slightly. If you hear the rotor spinning rapidly and making a clicking sound, it is the 7750 version. In the N Factory 4130 version, there is almost no sound since it is a bi-directional installation. Secondly, look at the crown stages: the old Daytona 7750 has a chronograph movement and the 7750 has three stages; The first stage is for winding, the second stage is for date setting, the third stage is for time setting. In other words, if you pull the crown slightly out of the crown and it lands on an empty slot, it is the 7750 version. The N Factory 4130 chronograph movement has only two stages: the first stage is winding, the second stage is time setting. Therefore, when you gently pull the crown out of the crown, you will go directly to the time setting, with no empty steps in between.

N Factory's Daytona models cover 90% of the range in official stores; In short, all new models released from the official store are available. Because there are so many photos, I can't post them all one by one. The mechanisms are common; In terms of durability, I would recommend you to choose models with silver cases.
