Hello, I’m CN Watch. I am passionate about sharing my in-depth knowledge on replica watches, comparing authentic and replica models, disassembling movement, and providing honest evaluations.Clean Factory GMT Master 2 Rolex – 126711.
Let’s now talk about the key features of the Sarsaparilla Bezel. Also known as the Black & Brown bezel. This bezel is made using the same advanced technology as the Coke and Inter Milan versions. The color transition between black and brown is seamless — giving a spliced-but-not-spliced visual effect that’s impressively close to the original. The black section is with zero color deviation while the brown segment achieves a 95%+ match from all angles.
This bezel was developed independently by Clean Factory and is unlike any version on the market. Soon, we’ll get into more detail about color comparisons.

Overview of Strap Craftsmanship This strap is made up of three sections and has been PVD-plated in 18K gold. The process is laborious and intricate because each section of the belt is individually plated. The sides of the strap are finished carefully to prevent any steel color from showing.
Clean Factory’s two-tone gold Submariner, made two years ago using the same technique, may be familiar to those who are familiar with the brand. Clean Factory considered abandoning this three-piece design due to its complexity. This led to a shortage of 40mm gold Submariners for a full year.
Clean Factory, in order to match the quality of the Sarsaparilla Bezel, brought back the craftsmanship — and added some hidden upgrades that were slowly revealed at the beginning of 2023.
Clean Factory maintains its high standards by using original molds to produce the dial, hands and crystal. Clean Factory adheres to the “no development, no original; no standard, not release” principle. It doesn’t try to be first, but rather strives to get it right.

Hour Markers (Nail part) The hour marks feature rounded corners that are in line with Clean Factory’s standards, and are perfectly aligned to the original Rolex specifications. It’s Chromalight that is used, but it is essentially Swiss-made luminous material. The price is around $400 RMB per kilogram. This is almost on par with the international gold price. The material is extremely hard to get, and requires corporate level procurement.
This lume has a fine, frosted texture and a crystalline finish. It emits an signature ice blue glow . Even many genuine Rolex watches have tiny dark spots on the lume. This is a result from the Chromalight compound.
This is a fun fact, which might seem unbelievable but it’s true.
When your markers are clean and free of black spots, you may want to consider buying a lottery ticket. These tiny imperfections are one of the telltale marks of authenticity. Yes, really.
Look at the close-ups of the cases. Clean Factory’s dedication to original development isn’t just words, it’s evident in the details.Clean Factory GMT Master 2 Rolex – 126711.

The image shows that the dark section has no color variation. Even the brown area maintains a consistent tone. does not show any signs of digital or post-adjustment. You can also compare the font and depth of the numerals with the original. The rose gold electroplated is also very similar.
Attention to the bottom-right image. Where brown and black meet on the bezel the ceramic insert from Clean Factory shows that it was formed as a single piece. Not two sections. The seamless transition from black to brown creates a patina effect just like the original.
To achieve the perfect bezel, we performed numerous tests in order to reproduce the exact boundary between two colors. We purchased 2 genuine watches to use as reference when opening the mold. We were surprised that the original bezel has a slightly curving boundary line, but this is part of Rolex’s actual manufacturing process.
This is a key point of identification: If the brown crosses the number “8”, without touching either the top or the bottom of the zero curves then this alignment meets the standard for the authentic version. It is because the two-tone ceramic bezels must account for shrinkage of ceramic during firing. This makes accuracy extremely difficult .

Three Segment End Link Design Clean Factory is the first to introduce this three segment end link structure. The process is so labor-intensive and complex that at one point, production was almost stopped due to its difficulty. This method has the biggest advantage that the interior of the links still displays rose gold when they are disassembled.
This process includes high loss polishing and precision assembly. The entire surface is finished with vacuum electroplating to ensure excellent durability and resistant to fading. The previous Gold Submariner from Clean Factory, which was sold two years ago, has been subjected to long-term use and returned products. The gold tone remained constant without any major discoloration. This is a testament to durability over time.
End link Section
The end link section also has the 3-segment splicing just like the original Rolex. Clean Factory recreates the original CNC-cut structure by splitting an end link into precisely three components, and then reassembling. The structure must perfectly match the case and be aligned in size and curve for a realistic look.

Buckle Section The buckle was fine-tuned on multiple levels, including engraving precision, tightness and feedback, as well as the locking strength of safety buckle. What is the result? The result? A “magnetic”-like closure that is smooth and secure, just like electrical suction. If you have never felt this smooth buckle before, will be able to show you what means.
Clean Factory reproduces the original hidden carving craftsmanship in the subtle areas where the strap meets case. We insist on these small details, not because they are trivial but because we put ourselves in our customer’s shoes. We believe that these details should be included, even if they are not noticed. This is our way to show respect to quality and a devotion to detail. No empty promises, just steady and honest work.

Dial section The overall dial has a high gloss enamel finish. As can be seen in the photos, the English fonts and crown are printed with a close alignment to the original. The print on an authentic GMT-MASTER is slightly rough. That’s because it is. Clean Factory adheres to the philosophy of retaining the essence and improving flaws . Therefore, some minor details have been refined instead of being blindly copied. We hope that watch enthusiasts will understand our choice. Our goal is to improve quality, not copy every flaw.
Handset The hands were designed strictly on the original model. The proportions and dimensions of Rolex watches may be similar, but they vary from model to model. Clean Factory purchases at least two pieces. One is disassembled to collect precise data for development and the other one is left intact for reference.

Yes, you read that right — the inner crown engraving on a genuine Rolex is not always perfectly aligned with the 12 o’clock marker. This isn’t a rare defect; many authentic pieces are like this. It’s not due to poor quality control, but rather because the 2.5x magnified date window at 3 o’clock needs to be precisely centered. To achieve this, the movement is often rotated slightly, meaning manufacturers must choose between perfect crown alignment or perfect date alignment.
In fact, even genuine Rolex watches sometimes have slightly off-center date windows. As shown in the image, it’s extremely rare to find a genuine piece where the crown logo lines up exactly with the 12 o’clock marker. So if you’re checking your watch, don’t treat crown alignment as a strict quality standard.Clean Factory GMT Master 2 Rolex – 126711.
