The Rolex Submariner Date 126613LB, widely known as the “Bluesy,” is one of the most recognizable luxury dive watches in the world. Its 41mm case combines stainless steel with yellow gold color, creating a bold and refined two-tone aesthetic. The vivid blue Cerachrom bezel features a unidirectional 60-minute scale designed for precise dive timing and exceptional durability. The striking blue sunburst dial shifts elegantly under changing light, complemented by Chromalight-filled hour markers and hands for enhanced visibility—even in deep underwater conditions. A date window at 3 o’clock, magnified by the iconic Cyclops lens, adds everyday practicality. With robust performance and timeless design, the 126613LB remains a standout piece in the Submariner collection.
