Rolex gold water ghost bag 18k real gold +904 steel. Equipped with a copy of the original cal.3135 mechanical movement, the stainless steel part is made of 904 steel, and each part of the strap has grains: each component of the first grain, the middle bead on the body, and the beer handle (the first section of the finger is down with beads on both sides) From the beginning to the dismantling of the raw strips), the stripping of the raw strips (referring to the screw holes and beads on both sides, which can be detached to adjust the length) are first made according to its shape through multiple processes to form a strip of about 2 meters in length. (Of course, there is a margin for processing and polishing), and then cut each grain to the required size by a high-precision automatic cutting CNC machine, and then the drilling process, such as drilling the holes on both sides of the body with the bead, the factory requires Round the orifice to make the steel residue from the orifice fall clean, so as to maintain the softness of the strap. The screw thread with the body is also used for the screw thread position with the original imported “tooth tap” car, so that each screw can be anastomosed and locked in smoothly. And each piece of watchband is polished in loose pieces and then assembled into finished products. After the assembly is completed, use precision fixtures to assist in grinding the slopes on both sides… Special mention is that the Rolex crown LOGO on the steel buckle is carved with high-speed precision CNC, which is consistent with the original version! It should also be noted that the multi-angular surface and the turning circle of the handle of this watch are all cut with a special “diamond knife” to keep the groove and surface smooth.
