replica audemars piguet Audemars Piguet (Audemars Piguet), Switzerland's top watchmaking brand, caused a sensation in the watch industry when it launched the Royal Oak series. Before it, the watch industry has never seen a luxury watch with a steel case. The launch of the Royal Oak series also announced the birth of the first stainless steel luxury watch. The price is not lower than the precious metal watch, creating a steel watch. As expensive as the gold watch. As we all know, the basic material of stainless steel is steel, and steel is obtained from iron. The iron ore is smelted in an elevated temperature furnace by an electric furnace steelmaking process or an electric arc steelmaking process. The pig iron obtained by these methods has a high carbon content and a large amount of impurities, is very brittle, cannot be used, and is subjected to further processing. The pig iron will be further processed by techniques such as alkaline oxygen blowing. The liquid pig iron water at a high temperature is filled into the converter vessel, and then oxygen is blown into the molten iron with a high pressure, and the mixture is heated to 1,650 degrees Celsius.
In this fake watches for sale process, impurities in the pig iron are oxidized and the gas or slag is removed. After the impurities are removed, different types of steel are made according to the composition and use. Among them, only steel of a certain purity can be called stainless steel. Don't underestimate the steel used in the watch, it is very difficult to handle, these steels of a certain purity can only be treated with particularly tough tools. After complicated pretreatment and fine grinding, the watch can be provided with suitable construction materials.
The high-quality case must be manufactured and post-processed to a perfect appearance. First, the metal strips for the case are stamped out of the basic shape by means of an abrasive tool, and these tools are separately produced according to the shape and size of each case. After the first stamping, the final shape of the case cannot be obtained, and a very complicated multiple stamping process is required. Only the bottom of the case requires up to 10 to 15 punches to be completed. Then, the blank case is further processed by casting, turning, and the like. In order to solve the internal stress generated thereby, heat treatment must be performed after each process to heat the metal to about 1,000 degrees Celsius. After the heat treatment, the case must be cleaned, the burrs removed, and the edges polished with a sanding stone.
After the replica swiss watches case is formed, the polisher will use its superb skills to eliminate the processing marks of the case and restore the bright luster of the metal surface. Add a lubricant to the round grinding wheel or sanding belt for sanding. From the first grinding process to the next grinding process, the lubricant used is getting finer and finer. After two or three fine grinding, polishing, brushing, matt, etc. according to the needs, showing the final look of the case.
Audemars Piguet's Royal Oak series stainless steel watches have more unique shapes and more cutting surfaces. They need to overcome more technical challenges than ordinary steel watches. The iconic stainless steel octagonal bezel requires 70 hand-finishing processes to polish and polish the eight bevels after cutting. Eight white gold screws also require polished finishes. The single-piece case still requires 44 steps to complete the sanding after the stamping best swiss replica watches process.
