Hello everyone, this is the official blog editor from Clean Factory. Today, we’re taking a detailed look at the Clean Factory GMT-Master II with the black and grey dual-tone bezel, popularly known as the “Century Egg”. This model is a fairly new release, having been on the market for only about two months. Several factories are producing this reference, but the leading contenders are ARF, C+, and Clean Factory.
Shared Components, Different Cores
When it comes to the external parts like the case, bezel, dial, and hands, all three factories—ARF, C+, and Clean—source them from the same high-level OEM supplier. That means in terms of exterior appearance, there’s virtually no difference. The steel bracelet, ceramic bezel insert, and case profile are indistinguishable across these brands.
Why Clean Factory Leads
So what makes Clean Factory stand out? The answer lies in the movement. Clean Factory uses the Dandong 3285 automatic movement, which is currently considered the most stable clone of Rolex’s original caliber 3285. While both ARF and C+ factories also utilize 3285 movements, Clean Factory’s version tends to show superior consistency and reliability in power reserve and timekeeping.
If you’re purely chasing the best value-for-money replica, ARF and C+ still offer great alternatives. But for those seeking the most faithful replica both inside and out, Clean Factory remains the top recommendation.
Movement Comparison and Color Variants
There’s also an older all-black bezel version that uses the older 3186 movement. The main differences lie in the movement type and bezel color. The black-grey model (Century Egg) comes with the newer 3285 movement, which provides enhanced stability and accuracy.
This dual-tone aesthetic is very attractive and has a modern, sporty feel. The watch is available with both Jubilee (five-link) and Oyster (three-link) bracelets. In this review, we’re showcasing the Jubilee variant, which is more popular for its youthful appearance.
Fine Details and Finishing
The bracelet and clasp feature deep, laser-engraved markings with a fully integrated, brushed clasp mechanism. These bracelets are produced by AR’s OEM supplier and are renowned for their comfort and robust construction.
Some users have asked why the bezel on this GMT doesn’t make a clicking sound like the Submariner. That’s completely normal—GMT bezels rotate differently. One full click equals 2.5 minutes, so turning the bezel twice moves the time by 5 minutes. This is a design trait of all GMT-Master II models and not a defect.
Conclusion
In summary, Clean Factory’s GMT-Master II “Century Egg” with the Dandong 3285 movement stands as the best full-package replica currently available. It combines an ultra-faithful external build with one of the most reliable cloned Rolex movements. Whether you’re a first-time buyer or a seasoned collector, this model offers exceptional quality, function, and aesthetics.
