Is there a noticeable color difference between the Clean Factory Rolex GMT Master II Coke​ and the Dandong 3285″ movement?

Hi everyone, I’m CN Watch. I love to share my knowledge about replica watches, whether it’s through detailed disassemblies or hands-on evaluations. I want to be your guide through the world of collecting watches, helping you find your way without getting lost.Rolex GMT Master II Coke​.

The focus of today’s review is the Clean Factory Rolex GMT “Coke” bezel, upgraded with the exclusive Dandong 3285″ movement. Rolex GMT Master II M126710BLRO-0101 (Coke bezel) is the official reference. Clean Factory released the 3186 model before, so the focus of this update is the 3285 movement. For those who are interested, I have already provided a detailed breakdown of the Dandong 3185. In this review, however, we will focus on one key question: Does the new 3285 version Clean Factory Coke bezel show a color difference from the original? Let’s see.

In 2018, Rolex launched the “Pepsi”, a steel GMT-Master II, with a Cerachrom ceramic bezel in red and blue. It was the first time that the Jubilee Oystersteel (five-links) bracelet had been paired with the GMT-Master II. The new Oyster bracelet was designed to differentiate the steel model from the platinum one. Rolex only offered the “Coke’ bezel in Platinum, and never in Steel.

Rolex added the five-link Jubilee band to the steel version and changed the case lugs so that it could not be replaced with an Oyster. The platinum model now has a blue dial to further differentiate it from the steel version. The new red and steel GMT-Master II is also a major upgrade. The new Caliber 3285 Rolex movement (Ref. 126710) increases the power reserve of the watch from 48 to 70 hours. The tiny crown logo is a visual clue for this upgrade. It’s located just below the 6 o’clock marker on dial.Rolex GMT Master II Coke​.

Clean Factory and C+ Factory currently produce the best replicas on the market of the Rolex Coke Bezel. Clean Factory released the first-generation model, which was powered by the 3186 movement. They corrected bezel alignment problems found in earlier N Factory versions. C+ Factory then released an improved version that had more refined details. C+’s model was equipped with a 3285 re-coded movement but the power reserve could not reach 72 hours.

Clean Factory now offers a replica Rolex Coke bezel featuring the Dandong 32855 movement. The movement was tested and found to have a 72-hour reserve. It also corrects a problem with the 3186, which saw the hour hand move in the opposite way to the original model when setting time. The Dandong 3185 not only has enhanced performance, but it also aligns perfectly with the original version when it comes to hour and minute hands, date adjustment and crown rotation.

Before we get into the review, it’s important to note that there is a difference between Ref. The 126710 was released in early 2018, and the same model will be launched in 2019 or 2020. The ceramic bezel of the early 2018 model features a pinkish red and bright blue color scheme. This is commonly known as MK1. The later versions, also known as MK2, adopt a dark blue and burgundy tone.

At first, some enthusiasts thought this was a minor difference caused by Rolex’s ceramic firing process. Since the MK1 color combination of the bezel never re-appeared, it is now recognized as batch-specific.

The MK1 color was not quite the intended red tone of Rolex. However, the MK2 color became the standard color for all subsequent models. It also set the benchmark for replicas. The MK2’s red is a true, burgundy color, while the blue has a deeper tone with a hint purple, creating a refined, balanced appearance.

Clean Factory is truly unique in this respect. The bezel is the most accurate version on the market, as it accurately captures MK2’s color tone. Clean has been developing replacement bezels for years, so it’s not surprising that they have maintained their leadership position with consistent quality and expertise.

At first glance, the bezel color holds up impressively well. Clean Factory’s bezel not only features a smooth and seamless transition between the red and blue sections, but it also appears more refined and natural overall. Additionally, the alignment of the 18 and 6 numeral markers is precise, and the matte finish of the platinum numerals on the bezel is particularly well-executed. The texture is fine, evenly distributed, and clean—showing no signs of roughness or inconsistency.

When it comes to finer details–particularly the crown engraving on the inner bezel and the alignment of the triangle marker on the dial–it’s clear that everything lines up perfectly along a central axis. This alignment can be judged by the angle in the picture below. Clean Factory did a fantastic job with this, and the images speak for themselves.

You can choose between a three-link or five-link bracelet depending on your preference. The strap is extremely comfortable and feels smooth.

The case sides are polished to a smooth, rounded finish. This gives the watch an elegant appearance. The time-setting crown on the right features a sharp, precise engraving. The back of the case is a solid, classic design. Clean Factory upgraded the movement from the 3186 caliber to an authentic 3285-style movement. This is not just a 3186 movement with re-engraving but a fully-functional and properly implemented 3285-style movement.

This time, the integrated 3285 movement developed by Dandong delivers an impressive 72-hour power reserve. It not only corrects the rotation direction of the hour and minute hands when adjusting the date and time, but also stands out for its extended energy storage. After precise calibration, the movement offers excellent stability. With these advantages, Clean Factory’s Rolex GMT Master II Coke​ bezel is clearly one of the top-tier versions available on the market today!
