Reference: M79000-0001 A Faithful Revival of Tudor’s Earliest Diving Heritage The Tudor Black Bay 54 is a masterful return to the brand’s origins, inspired by the historic Tudor Submariner reference 7922 from 1954. Compact, elegant and purpose-built, this watch celebrates understated tool-watch design with modern Swiss engineering. Its clean proportions and vintage-correct details make it one of the most talked-about Tudor releases in recent years. Crafted in stainless steel with a refined 37mm case, the Black Bay 54 offers exceptional comfort while retaining the robustness expected of a professional dive watch. Key Features at a Glance 37mm stainless steel case – faithful vintage proportions Unidirectional stainless steel bezel with mirror-polished insert Black domed dial with gilt accents and iconic Snowflake hands Manufacture Calibre MT5400 – COSC-certified chronometer 70-hour power reserve 200m (660ft) water resistance Stainless steel bracelet with Tudor “T-fit” clasp Sapphire crystal Swiss Made Design & Craftsmanship The Black Bay 54 stands out for its purity of design. The absence of crown guards, combined with gilt dial printing and softly domed crystal, delivers a distinctly vintage aesthetic without sacrificing modern performance. The polished steel bezel is a particularly striking detail — a nod to early dive watches before aluminium inserts became standard. Paired with the slim profile and classic lug width, the watch wears effortlessly on a wide range of wrists. Manufacture Movement: Calibre MT5400 At the heart of the Black Bay 54 is the Tudor Manufacture Calibre MT5400, a self-winding mechanical movement engineered for reliability and precision. Certified by the Official Swiss Chronometer Testing Institute (COSC), it exceeds industry standards for accuracy and durability, offering peace of mind for everyday wear. Collectors’ Notes The Tudor Black Bay 54 has quickly become a standout piece among collectors due to its historically accurate sizing, no-date symmetry, and faithful homage to Tudor’s very first dive watch. In an era dominated by oversized sports watches, the return to a true vintage 37mm case has been widely praised by enthusiasts and purists alike. Its restrained production feel, coupled with strong demand, positions the Black Bay 54 as one of the most desirable modern Tudor references — a future classic in the making.
