Even a closer look reveals the excellent finish, such as the color transition on the bezel. 
The second problem was achieving the desired red color for the blue-red Pepsi bezel, as there were no mineral-based pigments capable of producing a rich red color. After years of research, Rolex replica came to rely on a ceramic-based ceramic with the addition of chromium oxide, magnesium oxide, and rare earth oxides to produce the red portion of the ceramic bezel. To obtain the blue color, half of the bezel was again saturated with a metallic salt solution before being sintered.
The bezels of Batman and Pepsi are based on different ceramic substances, namely zirconium oxide and aluminum oxide, which explains why the blue color of the two bezels looks so different. On our test fake watch, the blue color looks much brighter than on the new Pepsi model. However, incident light plays a major role in our perception of color and, as usual, there are subtle differences between the Pepsi bezels.
Both materials used to form the track condense and shrink during the sintering process and must be worked to exact dimensions using diamond tools. To ensure that the numerals remain perfectly clear, the entire ring is coated with platinum using a PVD process and then carefully polished to leave the precious metal in the recessed dots and numerals. Both processes are proprietary to Rolex. In addition to being scratch-resistant, ceramic bezels have the added advantage of being UV-resistant and will not fade.
Rolex GMT-Master II “Batman”&”Pepsi” watches – flat
The shades of blue on the bezels of Batman and Pepsi are distinctly different. And it’s no wonder: they are based on different ceramics.
Extended Power Reserve
Like Pepsi, the updated Batman features the new time zone Caliber 3285. All Rolex self-winding replica watches, with the exception of the chronograph, are powered by either the Caliber 31xx (the old version) or the new Caliber 32xx, which has a 70-hour power reserve instead of 48 hours. Unlike the Caliber 3186, the new movement has a ball-bearing rotor. The proprietary Paraflex shock absorber is designed to improve performance in the event of a shock. But the biggest benefit for the wearer is the increased power reserve – instead of two days, the watch now offers almost three full days of power, largely due to the more efficient Chronergy escapement. The geometry of the pallet fork and escapement wheel has been optimized, and through the LIGA plating process, copy Rolex was able to create cut parts that are lighter in weight. The escapement is made of nickel-phosphorus alloy and is not affected by magnetic fields.
The well-known features of a Rolex movement remain unchanged: the extremely robust balance cock (instead of a unilateral balance chuck), the free spring with an overcoil made of paramagnetic niobium-zirconium alloy, and the fine regulator with a Microstella weight on the balance. The movement can be adjusted using a special tool without removing the movement from the case.
Rolex has improved the movement in terms of its core virtues of accuracy, longevity, and robustness. The decoration includes a sunburst motif. Hand engraving is not present and does not have the desired effect. The new movement can be easily identified by a small detail on the dial: a small Rolex crown has been inserted between the words “Swiss Made”.
