TUDOR Black Bay 54 Lagoon Blue: An Iconic Dive Watch with a Vintage Spirit

The TUDOR Black Bay 54 Lagoon Blue (reference M79000-0001) is much more than a watch. Inspired by the legendary Oyster Prince Submariner ref. 7922—TUDOR’s first dive watch, tested and adopted by the French and US Navies—this model pays tribute to the past while incorporating the best of contemporary watchmaking technology.

Design and Materials: Timeless Elegance in Stainless Steel

Featuring a 37 mm stainless steel case, the Black Bay 54 offers perfect proportions for the modern wrist. Its polished and satin finish, along with the mirror-polished steel unidirectional bezel, evokes the essence of classic dive watches. The domed and textured blue dial—known as Lagoon Blue—brings a fresh and evocative feel, reminiscent of the celestial tones of paradisiacal lagoons and white sand beaches.

Movement and Performance: Certified Precision

Inside, the Manufacture Calibre MT5400, with COSC certification, ensures high-precision performance. This self-winding mechanical movement features a bidirectional rotor system and a generous power reserve of approximately 70 hours, ideal for any adventure. The Black Bay 54 is water-resistant to 200 meters, making it a reliable companion both on land and underwater.

Comfort and Functionality

The five-link stainless steel bracelet, with a polished and satin finish, incorporates the TUDOR “T-fit” clasp, which allows for a precise and comfortable adjustment in any situation. The screw-down crown, featuring the TUDOR rose in relief, completes a design that balances tradition and modernity.
