⚡ Quick Verdict (TL;DR)
If you don’t have time to read the full 2,000-word review:
The Clean Factory (CF) GMT Master II “Wayne” (Black & Grey) is currently the most sophisticated GMT Master II replica on the market. It mimics the subtle “ghost” transition of the genuine ceramic bezel perfectly.
- The Bezel: The Black/Grey transition is seamless and smoky, exactly like the genuine Rolex GMT Master II.
- The Movement: Powered by the Dandong 3285 Super Clone (70+ hours power reserve).
- Realism: 9.8/10. It is even harder to “call out” than the Pepsi because the colors are more muted and precise.
Score: 9.8/10. Highly recommended for daily wear.

1. Introduction: The Rise of the “Bruce Wayne” GMT Master II
When Rolex released the GMT Master II 126710GRNR (Black & Grey) in 2023, the watch world was divided. Some called it boring; others called it the ultimate stealth luxury watch. It quickly earned the nickname “Bruce Wayne” (or just “Wayne”) for its dark, monochromatic look.
In the replica world, this GMT Master II model has become a massive hit for one reason: It is easier to replicate perfectly than the Pepsi.
Unlike the Pepsi (Red/Blue), which requires complex color mixing, the Black/Grey bezel relies on subtle gradation. Clean Factory mastered this immediately. While other factories struggled with the grey tone (making it too light or too dark), Clean Factory produced a version that is terrifyingly close to the genuine Rolex GMT Master II.
In this review, we dissect the Clean Factory GMT Master II Black & Grey. Is it really flawless? Or are there hidden tells?

2. The Ceramic Bezel: Mastering the Grey Tone
The bezel is the defining feature of any GMT Master II, and this one is special.
The Grey Half (The Hard Part)
The bottom half of the bezel is not just “grey.” It is a specific shade of gunmetal grey that changes under different lighting.
- Indoors: It looks subtle, almost blending with the black half.
- Outdoors: Under sunlight, it turns into a distinct, metallic grey.
- Clean Factory Execution: Clean has nailed this chameleon effect. Older or cheaper GMT Master II replicas use a flat, light grey that looks like plastic. Clean uses a high-density ceramic that mimics the genuine depth perfectly.
The Transition
The line where Black meets Grey (at 6 and 18) is flawless.
- It is not a sharp, printed line. It is a seamless fusion of two ceramic colors.
- Under a loupe, you cannot see a jagged edge. This is high-level manufacturing.
The Platinum Markers
The numbers are engraved deeply and filled with Platinum PVD. This ensures they sparkle silver-white under light and won’t turn yellow over time, a common issue on cheap GMT Master II replicas.
3. Case & Finishing: The 904L Experience
A luxury watch must feel like a luxury watch. The GMT Master II is famous for its balance of sport and elegance.
Real 904L Steel
Clean Factory uses genuine 904L stainless steel.
- The Shine: It has a brighter, whiter luster than standard 316L steel.
- Polishing: The sides of the case are mirror-polished with zero distortion. The top of the lugs features fine, directional satin brushing, matching the genuine GMT Master II finish.
Case Dimensions
- Diameter: 40.2mm (Genuine is 40mm, the 0.2mm difference is invisible).
- Thickness: 12.1mm (Exact match to genuine GMT Master II).
- Lug Shape: Clean Factory V3 case has corrected the lug taper. It is now slimmer and curves naturally around the wrist.
4. Dial Analysis: Green Hands & Crisp Fonts
The “Wayne” GMT Master II uses the classic black dial but with a distinct green GMT hand.
The Green GMT Hand
The 24-hour hand is painted in Rolex green.
- Color Accuracy: Clean Factory matches the vibrant, forest green shade perfectly. It provides the only pop of color on the entire watch.
- Stack: The hand stack (Hour-GMT-Minute-Second) is correct, thanks to the 3285 clone movement inside this GMT Master II.
The Printing
- Font: The “GMT-Master II” text is printed in white (unlike older models which were green). The font is crisp, slightly raised (3D effect), and has sharp serifs.
- Lume: The markers are filled with blue Chromalight. The application is neat, with no spillover on the white gold surrounds.
5. Crystal & Cyclops: The “Black Hole” Effect
One of the biggest “tells” of a fake Rolex used to be the date window.
- Black Hole Effect: Clean Factory uses a high-quality sapphire crystal with blue AR coating under the cyclops. This cuts the glare and makes the date wheel look “black” and readable from any angle—a hallmark of the Rolex GMT Master II.
- Crystal Height: On the V3 version, Clean has lowered the crystal gasket height. It no longer sits too high above the bezel, fixing a common complaint from V2 owners.
- Laser Etched Crown: The tiny Rolex crown at 6 o’clock is present but nearly invisible—just like the genuine.
6. The Engine: Dandong 3285 Super Clone
This is the heart of the beast. To be a top-tier GMT Master II replica, the movement must be perfect.
Why “Dandong” Matters
There are two main movements for GMT Master II replicas: Shanghai 3285 and Dandong 3285.
- Shanghai: Cheaper, reliable, but winding feels gritty and power reserve is ~40 hours.
- Dandong (Clean uses this): Premium, buttery smooth winding, and 70+ hours power reserve.
True GMT Function
This is a “Traveller’s GMT.”
- Jumping Hour: You set the local time by jumping the hour hand in 1-hour clicks. The watch keeps running.
- Date Setting: You set the date by cycling the hour hand.
- Accuracy: Our test unit ran at +4 seconds/day, which is COSC-level performance.
7. Bracelet: Jubilee vs. Oyster
The GMT Master II 126710GRNR is sold on both bracelets. Clean Factory makes both flawlessly.
The Jubilee (Five-Link)
- The Vibe: Dressier, hides scratches, feels silky on the wrist.
- Build: Solid End Links (SEL) fit tight against the case. No gaps.
The Oyster (Three-Link)
- The Vibe: Sportier, simpler.
- Build: Polished Center Links (PCL) add a touch of flash.
The Clasp
Both use the Oysterlock safety clasp with Easylink (5mm extension). The “beak” of the clasp feels solid when snapping shut. The internal engravings are clean and deep.
8. Real Comparison: Clean vs. Genuine GMT Master II
Can you spot the difference in real life?
What is Identical?
- Case Feel: The weight and balance are spot on.
- Bezel Action: The bi-directional bezel rotation feels smooth and dampened, not clicky and cheap.
- Dial: To the naked eye, it is 1:1 with the genuine GMT Master II.
The Tiny “Tells” (Expert Level)
- Crystal Clarity: The genuine Rolex crystal is still 5% clearer than Clean’s. It’s subtle, but side-by-side, the Gen pops a bit more.
- Date Wheel Font: The genuine date font has slightly sharper serifs on numbers like “1” and “7”.
- Winding Feel: While Dandong is smooth, the genuine 3285 is totally silent and effortless.
Verdict: On the wrist, even a seasoned GMT Master II collector would struggle to call this out without holding it.
9. Pros & Cons
✅ The Pros
- Best Grey Bezel: No other factory captures the “Wayne” grey tone this well.
- Top-Tier Movement: Dandong 3285 is the industry standard for GMT Master II reliability.
- Stealth Wealth: It’s less flashy than the Pepsi, making it a great daily wearer.
- Build Quality: 904L steel and ceramic ensure it lasts for years.
❌ The Cons
- Crystal Height: Still a tiny bit higher than genuine (microscopic issue).
- Rotor Noise: Faint noise in a silent room (common for clones).
10. Final Verdict: The Best Daily Wearer?
If the “Pepsi” is the loud, iconic rockstar, the Clean Factory GMT Master II “Wayne” is the sophisticated secret agent.
It is arguably better than the Pepsi replica for one reason: The colors are easier to get right. The risk of someone spotting a “fake color” on the Pepsi is low; on this Black/Grey GMT Master II, it is practically zero.
