Owning its own foundry, Rolex possesses an exceptional capacity to produce the highest quality 18-karat gold alloys. Depending on the proportions of silver, copper, platinum, or palladium used, different types of 18-karat gold are obtained: yellow, rose, or white.

All alloys are made with the purest metals, which are carefully analyzed in a Rolex laboratory using state-of-the-art equipment, before the gold is shaped and molded according to rigorous quality criteria. Rolex's commitment to excellence is established from the creation phase.
