Gem-setting craftsmen, like sculptors, carefully craft the setting for each gemstone by hand using precious metals. The craftsman sets the gemstones with extremely precise skills. Each gemstone is precisely arranged and calibrated in its position to ensure that it is firmly decorated on the gold or platinum setting. In addition to paying attention to the quality of gemstones, Rolex also has other strict requirements on gemstone setting, including the height and precise arrangement, direction and position of gemstones, the regularity, firmness and proportion of setting, and the exquisiteness of metal setting. Surface Modification. The watch brings a dazzling embellishment to the wearer's wrist.

gold
Rolex has its own foundry, which casts high-quality 18K gold alloys. By mixing different amounts of silver, copper, platinum or palladium, different types of 18K gold can be extracted: gold, pink gold or white gold. All raw materials are made of high-purity metals. Before the gold is formed, it must pass the careful inspection of advanced equipment in the self-operated laboratory. Every process is meticulous. The relentless pursuit of excellence from the source of production is the consistent persistence of Rolex.
