Clean Factory GMT-Master II Replica Introduction
Clean Factory is renowned for its attention to detail, especially when it comes to the ceramic bezel inlay and case finishing. Their latest GMT-Master II replica, model M126713GRNR-0001, attempts to replicate the iconic Rolex design in a Rolesor (steel and gold) configuration, with a black dial and a gray-black Cerachrom ceramic bezel. The watch has a 40mm case, made of 904L stainless steel (to authentic Rolex specifications), and 18K gold-plated center links on the Jubilee bracelet.
What sets Clean Factory apart is that it is committed not only to replicating the look of authentic Rolex watches, but also the functionality. Their version uses a modified automatic movement that mimics the workings of the Rolex caliber 3285, including independent GMT hand adjustment and jump hour function for quickly switching time zones.
Case and bezel comparison
Case material and finish
Authentic Rolex: Made of 904L stainless steel (Oyster steel), with 18K pure gold center links. The brushed and polished surface of the case is perfectly balanced, with sharp and consistent edges.
Factory replica: Also made of 904L stainless steel, a significant upgrade over the 316L steel used by many other replica watch factories. The gold plating on the center links is wrapped in real gold, rather than simply electroplated, making it more durable.
Bezel assembly (gray and black Cerachrom bezel)
Authentic Rolex: Cerachrom (ceramic) bezel has clear and sharp numbers and platinum-filled scales. The color transition between gray and black is seamless, and the bezel rotates smoothly with 24 precise clicks.
Clean Factory Replica: The ceramic bezel matches the original’s color scheme perfectly. However, under a loupe, the platinum-filled numerals may appear slightly less vivid, and the filling depth is slightly different. The bezel rotation is improved over previous versions, but may not be as silky smooth as the original.
Case Dimensions
Both watches are 40mm in diameter and approximately 12.5mm thick, and the Clean Factory Replica has successfully replicated the proportions of both.
Dial and Hand Inspection
Dial Details
Original Rolex: The printing is beautiful, and the hour markers are clear and sharp. The black lacquered dial has a subtle sunburst effect in direct light.
Clean Factory Replica: The dial printing is excellent at normal viewing distance, but under high magnification, the edges of the text and hour markers lose a little clarity. Luminous coating (genuine Chromalight) is very close in color and brightness, but may fade slightly faster.
Hands and GMT Function
Authentic Rolex: GMT hand moves smoothly in one-hour increments when adjusted, and all hands are perfectly synchronized.
Pure Factory Replica: The improved 3285 replica movement achieves similar GMT hand adjustment functions. However, some users have reported slight inconsistencies in hand calibration when switching time zones quickly.
Jubilee Strap and Buckle Analysis
Jubilee Strap (Two-tone Steel and Gold)
Authentic Rolex: Five-link bracelet is flexible and strong, with a perfect transition from gold to steel at the center link.
Factory Replica: The strap structure is very tight, the links are the right size and the connection is good.The gold edging on the center link is well-made, but may wear over time.
Clasp mechanism
Original Rolex: Oyster clasp with Crown clasp extension system, fine-tunable and exquisitely crafted.
Factory replica: The clasp looks highly restored, but may not be as good when opening and closing. Easylink extension system works fine, but feels slightly worse.
Movement and functions
Original Rolex 3285 movement
Equipped with Rolex's proprietary Chronergy escapement, and
70 hours power reserve, ±2 seconds daily accuracy.
Local hour hand can be fully adjusted independently, in one-hour increments.
Clean Factory replica movement
Uses modified automatic movement (probably based on Shanghai or Dandong 3285 movement), emulating the functions of the original movement.
Power reserve is approximately 65 hours, slightly shorter than the original.
GMT hand can be adjusted similarly, but the incremental accuracy may be slightly lower.
