Rolex Explorer Replica Watches Hot Sale Watches
Most Swiss Replica Rolex Explorer II Watches companies use 316L steel for their cases, which is five times more durable than standard steel. But Rolex is the only one to use 904L steel, which is corrosion resistant, virtually scratch proof, and far more expensive than 316L.
904L contains chromium, which when mixed with oxygen, forms a thin, virtually impregnable barrier on the surface of the case. This alloy combination is so hard that Rolex had to develop a special 250-ton press capable of stamping a Rolex Explorer Replica Watches Hot Sale Watches case from a block of 904L.
