As we all know, the basic material of steel is steel, the steel is taken from the iron smelting. By EAF steelmaking process or electric arc smelting iron taken from, and also in a high temperature furnace for iron ore for smelting. Pig iron obtained by these methods, because of its high carbon content and impurities, very brittle, and can not be used to go through the treatment process again.
Pig iron will be further processed by the basic oxygen technology. The liquid pig iron at a high temperature to the converter up the water container, and then use high-pressure oxygen is blown into the molten iron, and the mixture was heated to 1,650 degrees Celsius. In this process, the iron impurities through oxidation, into a gas or slag are excluded. Exclude impurities and then made into different types according to the composition and use of steel in these, only reach a certain purity of the steel before it can be called stainless steel.

Do not underestimate the steel used in watches among these, very difficult to deal with them, they can only reach a certain purity steel using special tools for tough treatment. Even after pretreatment complicated and fine grinding in order to provide a suitable construction materials for the Swiss Audemars Piguet copy watch.
High quality of the case, must be a high level of production and post-processing to render the perfect look. First of all to the case for a metal strip punched out basic shapes with abrasive, and these abrasive according to each individual case to make the shape and size. After the first punch and the case can not be the final appearance, but also a very complex multiple stamping process, only the bottom of the case will take up to 10 to 15 times the press to complete.

Then after casting pressure, turning the case and so the blank further molding process. In order to solve the resulting internal stress must also be subjected to heat treatment after each process, the metal is heated to about 1,000 degrees Celsius. After the heat treatment, in the same manner, the case must be cleaned, deburred and polished with a grinding stone edges.

In case after molding, polishing division will eliminate traces of case processing with its superb artistry, reducing bright shiny metal surface. In a circular grinding wheel or belt, adding a lubricant for grinding. From the first step to the next one grinding or polishing, a lubricant used in more and more sophisticated. After two to three fine grinding, polishing according to demand, drawing, matte and other processes, and presents the final appearance of the case.

The Audemars Piguet Royal Oak stainless steel watch because of its unique shape, the cutting surface more than the general steel watch more processes need to overcome challenges. Iconic steel octagonal bezel after the cut type, we need 70 steps to manually retouch eight bevel grinding and polishing, eight platinum screws also need to be polished shiny polished. Case monocoque after the stamping process still needs to complete 44 step frosted.

Integrated strap process is more complex, varied lengths of strap links require a total of 138 hand-polished edges, so that each link reach completely symmetrical bevel effects, and visual beauty polished and matte staggered. These spend endless effort and ingenuity craftsmanship so that each one Royal Oak stainless steel watch presents a distinctive color, gentle but memorable, with lighting angle more a reflection of the light of wisdom and mystery, worthy of the steel sheet s King”.
