The Rolex Submariner with a silver (likely stainless steel) case, blue rotating bezel, and date display is a highly sought-after model, often referred to as a "Bluesy" when paired with a matching blue dial. This configuration is popular for its blend of sporty functionality and luxurious aesthetic. The blue bezel, often ceramic (Cerachrom), provides a striking contrast against the silver case and offers excellent scratch resistance and colorfastness. The rotating bezel with 60-minute graduations is a key feature for divers, allowing them to track immersion time. The date function, usually magnified by a Cyclops lens on the sapphire crystal, adds to the watch's practicality.
