These three models share the same aesthetic DNA, but are primarily distinguished by their diameter, proportions, and historical inspiration.
The Black Bay 54 has a 37mm case directly inspired by Tudor's first diving watch from 1954. Compact and elegant, it is particularly suitable for slender wrists or vintage watch enthusiasts.
The Black Bay 58 features a 39mm diameter inspired by a 1958 Tudor model. It offers an excellent balance between comfort, wrist presence, and versatility.
The Black Bay is generally offered in 41mm. More contemporary, it offers a wider variety of dial, bracelet, and complication options.
