Tudor Black Bay 54 "Blue Lagoon" - 37mm 79000-0001

Overview 

The new Tudor Black Bay 54 reference 79000-0001, affectionately nicknamed the "Blue Lagoon," is a highly anticipated timepiece that perfectly captures the essence of summer and the brand's deep diving heritage. Directly paying homage to Tudor’s first dive watch, the 1954 Reference 7922, this latest model offers a modern tool watch in an appealing, versatile proportion.

The watch is defined by its compact, historically accurate 37mm stainless steel case, which provides superb wearability on a wide range of wrists. The case features a polished and satin-brushed finish, and is topped with a smooth, polished steel bezel—a key aesthetic departure that adds a sophisticated gleam and maximizes its dress-watch versatility.

The defining feature of this edition is its captivating light blue textured dial. This vibrant, serene surface subtly evokes the crystal-clear waters of a pristine lagoon, playing beautifully with light to create a dynamic and inviting aesthetic. The dial retains quintessential Black Bay elements: the applied markers and the iconic "snowflake" hands, all filled with bold white Super-LumiNova for exceptional legibility. The thoughtful omission of a date window keeps the dial symmetrical and faithful to its pure, mid-century tool-watch inspiration.

Inside, the watch is powered by Tudor’s robust in-house Calibre MT5400, a COSC-certified automatic movement. This caliber features an anti-magnetic silicon balance spring and delivers an impressive 70-hour power reserve, making it "weekend-proof." The screw-down crown and 200-meter water resistance further emphasize its capabilities as a serious dive watch.

This "Blue Lagoon" model is expertly fitted with a refined five-link stainless steel bracelet which provides an exceptionally fluid and comfortable drape on the wrist. Equipped with Tudor’s highly functional T-Fit clasp system for instant micro-adjustments, the bracelet ensures a perfect fit. By merging retro aesthetics with cutting-edge technology and a refreshing, unique colorway, Tudor has created a highly desirable watch destined to become a staple for enthusiasts who value both heritage and modern style.
