As one of Rolex’s most classic chronographs, Shawn Yue’s Daytona has always been a popular style in the replica watch market. Today we are going to review the latest upgraded version of Yuwen Le Daytona launched by Factory C. What are the highlights of this new product equipped with Dandong 4131 movement?

Appearance design: details determine success or failure
Factory C Yuwen Le Daytona adopts the classic size of 40 mm diameter and 12.2 mm thickness. The overall proportion is coordinated and comfortable to wear. Although the official mark is 40 mm, the actual visual effect is closer to 38.5 mm. This design makes it appear more delicate and compact compared to other series such as Submariner. The disc surface is made of champagne gold tone, with radial patterns, and the slightly gray and black texture highly restores the color expression of the genuine product. Compared with the yellowish color palette of other brands (such as APS or VS), the color of the disk surface of Factory C is closer to the genuine product and is highly recognizable.

Factory C’s Yu Wen Le Daytona has put a lot of effort into the details:
- Dial color: Unique champagne gold tone, slightly gray and black radial pattern, very similar to the original product
- Ceramic ring: Newly added edge treatment to effectively protect fragile ceramic materials
- Mirror process: Fully transparent sapphire mirror with finely polished edges
- Case material: 904 fine steel with three-layer PVD vacuum plating, outstanding texture
Special reminder: The actual size is 38.5mm, which is smaller than the official 40mm. This is a feature that also exists in genuine products.

The mirror is made of sapphire and has been treated with fully transparent I0. It is clear and translucent from both the front and edge viewing angles, without any blurring. The edge of the ceramic ring has been wrapped, which not only improves the aesthetics, but also enhances durability and avoids knock damage caused by the fragile ceramic material. The golden scales on the bezel are delicate and neat, further demonstrating Factory C’s ultimate pursuit of details.
Movement performance: the strong performance of Dandong 4131
Factory C upgraded the original Shanghai 4131 movement to the Dandong 4131 movement, and its performance was greatly improved. The new movement can store up to 70 hours of energy, far exceeding the 38 hours of the 7750 movement, and its operating stability has also been significantly improved. The movement is exquisitely polished, the automatic rotor winds in two directions, the red wheel rotates smoothly, and the overall performance is comparable to the genuine product.


The upgraded version of Dandong 4131 movement is the biggest highlight this time:
- Power reserve increased to 70 hours (7750 movement only 38 hours)
- Stability far exceeds Shanghai 4131 version
- The movement is polished more finely
- Timing function operates smoothly
Through actual testing, the daily error of this movement is controlled within ±5 seconds, fully meeting the needs of daily wear.

This watch is equipped with a classic chronograph function layout: a chronograph minute hand dial at 3 o’clock, an independent small seconds hand at 6 o’clock, and a chronograph hand dial at 9 o’clock. It should be noted that the longest and thinnest hand is the chronograph seconds hand, which needs to be started and paused through the side button. This design is both practical and in line with the original logic, fully meeting the needs of timing enthusiasts.
Wearing experience: the perfect combination of comfort and practicality

Strap design:
The strap is made of fluororubber, and the embedded steel sheet has a buffering and memory function, which is not easy to deform and feels soft to the touch. The surface has a furry texture, and the slightly “dirty” effect is closer to the authentic characteristics, rather than ordinary rubber straps that are too smooth and shiny. The back cover of the dense bottom design is engraved with the AU750 precious metal logo and the dog head logo. The font is deep and three-dimensional. The anti-counterfeiting laser logo is extremely hidden and can only be observed at a specific angle. This detail perfectly restores the original design concept.
- Rubber strap with built-in steel plate with cushioning function
- The surface has a furry texture and is extremely durable.
- The clasp adopts a convenient fine-adjustment system that can be adjusted without tools.


Operation experience:
- The timing function operates smoothly: press the upper button to start, press again to pause, and lower button to reset.
- Crown operation feels smooth
- Dense bottom design ensures 100-meter waterproof performance
