Recently, many friends have been asking me about the differences between the two movements in the Rolex Daytona replica watch: the 7750 and the 4130. Their prices differ by several hundred USD. On our website, scgearwatch.com, we sell versions of these watches with both the 7750 and 4130 movements. So, what exactly are the differences between them? Today, I will analyze the differences between these two movements in Rolex replica watches.
Daytona 7750 vs. 4130 Movements
The fake Rolex Daytona is one of the best-selling replica watches on the market. Before 2018, the high-quality replica Daytona watches manufactured by Chinese factories used the 7750 movement. Due to the thickness of the movement itself, these replica Daytona watches were about 1.5mm thicker than the genuine ones. After 2018, following years of development and refinement, many replica factories introduced the 4130 movement. The upgraded 4130 movement has the same thickness as the genuine one, resulting in a 1:1 replica Daytona watch that perfectly matches the original.
Due to market and price considerations, the original 7750 movement was not discontinued. Because the 4130 movement is more expensive, many replica factories have upgraded the 7750 movement, especially the Citizen company in Japan, which has improved the 7750 movement to make the watch’s thickness almost identical to the genuine one.
How to Distinguish Between Rolex Replica Watches with 4130 and 7750 Movements
Measure the Watch’s Thickness
Generally speaking, a fake Rolex Daytona watch with a 4130 movement will have the same thickness as the genuine one. Our measurements show it to be 12.6mm, which is very accurate.
A Daytona with a 7750 movement is about 1.5mm thicker than the genuine one. If you happen to have a caliper, this method is a good way to distinguish them!
Open the Watch to Inspect the Movement
This method is rarely used because it involves opening a new watch. The latest 4130 movement has been significantly upgraded in terms of mimicry, with the font engraving on the plate also matching the genuine one.
Additionally, the 4130 movement uses a custom KIF shock absorber, which is a high-end movement shock absorber that offers more stable timekeeping. However, it is also more expensive.
Pull Out the Crown to Adjust the Time
This is the simplest and most practical method. If you unscrew the crown of a Daytona by turning it counterclockwise and pull it out to one position (there is only one position), and it allows you to adjust the hour and minute hands, then it is the 4130 movement. If you pull it out to the first position and it is empty, and then pull it out to the second position to adjust the hour and minute hands, it is the 7750 movement. This is because the 7750 movement originally had a date function, but the Rolex Daytona does not display the date, so the factory removed the date function. However, the date adjustment function cannot be modified. The 4130 movement was custom-developed by the factory and does not have a date function, so adjusting the time is the same as the genuine one, with only one position.
These are the differences between the 4130 and 7750 movements. At scgearwatch.com, we sell replica Daytonas with both the Japanese 7750 movement and the top-tier 4130 movement.
