Rolex has a dedicated foundry to develop high quality 18ct gold alloy. Different types of 18ct gold can be extracted by mixing different amounts of silver, copper, platinum or palladium: gold, pink gold or white gold. All raw materials are made of highly pure metal. Before the gold is formed, it must be carefully tested by the advanced equipment in the self-operated laboratory, and each process is meticulous. Since the beginning of the production, the pursuit of perfection is the consistent insistence of Rolex replica watches.
The unique Rolex watch dial makes the watch easier to identify and easier to read. The hour markers are made of 18 ct gold that lasts for a long time. Rolex designs and manufactures each Rolex dial in its own factory. Most of the processes are carried out by hand and are perfect.
The design, development and production of the Rolex straps and buckles, as well as the rigorous testing required to pass, are fully applied to advanced technology. Like other components of the watch, the strap and the buckle will also be checked by a person to ensure that the product is beautiful. The headgear strap is equipped with three rows of semi-circular links, specially designed for the ?-type perpetual motion calendar type watch introduced in 1956. This strap is crafted from carefully selected precious metals for an elegant and comfortable fit.
Week Calendar Type 36 The 3155 self-winding mechanical movement, fully developed by Rolex, is equipped with a day and date dial unit. Like all Rolex constant-core cores, the 3155 calibre is also certified by the Swiss Official Accreditation Timepiece, which is awarded to precision watches that have passed the Swiss Precision Timepiece Test Center (COSC). This movement is constructed in the same way as all ?-type movements with unmatched reliability.
The week-old calendar watch, which was introduced in 1956, achieved a remarkable innovation: it was the world's first watch with a calendar window and a full-write week on the dial. The calendar of the week is widely favored by multinational leaders, and the week is available in a variety of languages.
