By mixing different amounts of silver, copper, platinum or palladium, different types of 18ct gold can be extracted: gold, pink gold or white gold. All raw materials are smelted with high-purity metals. Before gold is formed, it must be carefully tested by advanced equipment in its own laboratory, and each process is meticulous. Rolex has always insisted on the unremitting pursuit of excellence since the source of production.
