About This Watch
The Tudor Black Bay Blue pays homage to the Tudor Submariner "Snowflake" references of the 1970s that featured blue bezels and dials. The rich blue aluminum bezel insert paired with a matching blue sunburst dial creates a striking nautical aesthetic that is instantly recognizable across a room. This particular shade of blue — deeper and more saturated than many competitors — has become something of a Tudor signature, earning the watch the affectionate nickname "Big Blue" among collectors. The 41mm case provides commanding wrist presence while the riveted bracelet adds a vintage character that modern alternatives from other brands simply cannot match at this price. The MT5602 caliber inside is the same proven manufacture movement that powers the black version, delivering COSC-certified accuracy and a robust 70-hour power reserve with a silicon balance spring for enhanced magnetic resistance. The date window at 3 o'clock adds daily practicality without cluttering the dial, and the snowflake hands provide distinctive character while ensuring excellent legibility in low-light conditions thanks to generous luminous material. The Blue Black Bay has developed a passionate collector following and remains one of the strongest sellers in Tudor's lineup. It offers an alternative to the ubiquitous black dive watch that is sophisticated rather than flashy, nautical rather than dressy. For blue dial dive watch enthusiasts, this is a benchmark reference at its price point.
