70 hours of battery life! Comprehensive review of the upgraded version of C Factory Blue Surface Log. Is it worth buying?

In the field of replica watches, Factory C (Clean Factory) has always been famous for its exquisite workmanship. Recently, its Rolex Datejust series has undergone a major upgrade. The new 3235 movement has increased the power reserve to 70 hours, solving the previous biggest performance shortcoming in one fell swoop. Today, we will fully analyze this “graduate-level” replica masterpiece!

The upgraded version of Factory C’s blue-faced log continues the classic aesthetics of the Rolex log series. The dial is designed with a dark blue radial pattern. No matter what angle it is viewed from, it will not appear purple or dark, and it highly restores the color performance of the genuine product. The platinum-plated ring is finely polished and will not oxidize or darken after long-term wear, ensuring durability. The sapphire mirror has extremely high transparency, rounded and smooth edges, and can present clear visual effects at any angle.

1. Core upgrade: new movement with 70 hours power reserve

This watch is equipped with a newly upgraded 3235 integrated movement, which can store up to about 70 hours of energy, which is comparable to the performance of genuine products. Different from the previous Shanghai 3235 movement, this movement is not a simple improvement, but adopts a new architectural design, which avoids the “hiding the ears and stealing the bell” type of card-free problem of the speed and slow piles, and greatly improves the stability. The gear set has a precise structure and all parts can operate realistically, showing excellent mechanical beauty. Whether it is the calendar instant jump function or the reverse calendar operation, they are completely aligned, and the use experience is extremely smooth.

The biggest highlights of this upgrade are:

  • Dynamic storage time doubled: Increased from 40 hours to 70 hours, comparable to VS factory Dandong 3235 movement
  • Bottom bracket workmanship upgrade: The new version of the movement makes the center axis of the pointer more refined and the “little hat” shape more three-dimensional.
  • instant calendar: Calendar font thickness is completely matched

2. Strive for perfection in appearance details

Factory C still maintains a very high degree of restoration. The five-bead chain strap fits the wrist and is extremely comfortable to wear. It is the soul of this watch. The dragon and phoenix logos, anti-counterfeiting dots and ORV codes on the inside of the Oyster buckle are all clearly visible, further enhancing the overall sense of sophistication. The small hat shape design on the central axis is also more compact, the cavity is smaller, and the overall look and feel is more natural. Thanks to the newly upgraded 3235 movement, the hands run more smoothly and stably.

  • Classic blue dial: Using a special coloring process to eliminate the purple cast problem and present deep radial patterns from multiple angles
  • Platinum plated bezel: Durable and non-oxidizing, bid farewell to the trouble of blackening and darkening
  • five bead chain design: Excellent fit and comfort, perfectly restoring the original soul

3. How to identify the real C factory?

  • Dynamic storage test: It takes about 70 hours under full chain status
  • Movement characteristics: Non-Shanghai movement modification, the card-free design is closer to the original version
  • Detail identification: Anti-counterfeiting features such as ORV code, dragon and phoenix logo on the inside of the buckle

4. Market positioning analysis

Compared with VS factory, C factory has more obvious advantages after this upgrade. Although the Dandong 3235 movement of the VS factory also has 70 hours of energy storage, the C factory is obviously better in terms of appearance details and overall workmanship. Especially in terms of the pointer center axis and dial color, Factory C’s performance is almost impeccable, perfectly meeting consumers’ stringent requirements for high imitation watches.

Previously, the VS factory had an advantage with the Dandong 3235 movement, but after the upgrade of the C factory:
✔ Superior appearance and workmanship
✔ Movement performance remains the same
✔ The five-bead chain is extremely comfortable
It has become the well-deserved first choice version of the Datejust replica!

Buying advice:
For watch friends who pursue perfection, this upgraded version of the Datejust can be called a “one-stop” choice. Whether it is for daily wear or collection, it can meet the most discerning requirements. It is recommended to give priority to the five-bead chain version to experience the most authentic Rolex classic design.
