Tudor · Family: Black Bay
The Tudor Black Bay 54 (ref. M79000N-0001) is a 37mm steel dive watch, with a black dial, a black aluminum unidirectional bezel devoid of minute graduations, and a design directly inspired by the 1954 Oyster Prince Submariner ref. 7922, Tudor's first dive watch. It runs the in-house Caliber MT5400, COSC-certified, with ~70 hours of power reserve and 200m water resistance. Cazador has no verified price observations yet for this reference. Its differential: it's the smallest-diameter Black Bay model in Tudor's current catalog, introduced in 2023 as a direct tribute to the brand's founding dive watch.

In 1954, Tudor introduced its first dive watch, the Oyster Prince Submariner ref. 7922, a model that was tested and adopted by the French and US navies and widely used by diving professionals of the era. That reference is the historical starting point for the entire Black Bay family, which Tudor relaunched in 2012 as a dive-watch line with an aesthetic inherited from its models of the 1950s through 70s.
The Black Bay 54, introduced in 2023, revives the proportions of that original 7922 reference more directly than any other model in the family: a 37mm case, notably more compact than the classic Black Bay's usual 41mm, and a bezel devoid of minute graduations, just as the 1954 model carried.
Beneath the black dial, with dot and baton indexes and no date, sits the in-house Caliber MT5400, an automatic movement with COSC certification and roughly 70 hours of power reserve, which Tudor has designed and manufactured internally since it began transitioning to in-house movements starting in 2015.
With 200 meters of water resistance, a domed sapphire crystal, and a steel bracelet with a quick-adjust 'T-fit' clasp, the Black Bay 54 keeps the original model's dive-tool vocation, in a case format that steps away from the trend toward larger diameters and revives the brand's historical proportions.
This is the fifth Tudor reference Cazador adds, alongside the Black Bay executions already in the catalog, extending coverage to this smaller-diameter execution.
