The Rolex Datejust strap material is a combination of gold steel, Oyster steel and 18ct gold.

18ct gold is cast by Rolex’s own foundry and then sent to the factory for processing. The shaping, machining and polishing processes receive even more careful care, allowing 18ct gold to exude its unique sparkling brilliance.

Rolex registered Rolesor (gold steel) as a trademark in 1933. Since then, the combination of gold and steel has become one of the iconic features of Rolex watches. Rolesor combines these two metals: gold, which is noble, precious, lustrous and stable, so it is very attractive; steel, which is unbreakable, strong and trustworthy.
