By operating its own foundry, Rolex has the ability to cast the highest quality gold alloys, melting the noblest of metals at over 1000 °C. By varying their proportions, yellow, white or Everose gold is created according to jealously guarded formulas, to ensure the exceptional durability and extraordinary sheen of Rolex gold watches. http://on.rolex.com/YcWgyk
