The New Tudor Black Bay 54 Blue

Tudor’s Black Bay line has grown steadily over the years, moving from the larger early models to more compact and more wearable formats. After the original Black Bay and the Black Bay 58, as well as the oversized Black Bay 68, the Black Bay 54 came in as the smallest of the lot, not to mention one that is most closely inspired by the early Submariner-style watches. Part of its success is about its 37mm case and a time-only display that makes it a clean, no-frills dive watch in the collection. Now at Watches and Wonders Geneva 2026, Tudor added another version with the Black Bay 54 Blue 79000B. Nothing drastic here, just a new colour, but sometimes that is all you need to change the mood of a watch.

The Black Bay 54 has always stayed quite close to the Oyster Prince Submariner reference 7922, Tudor’s first dive watch from the early 1950s. You still get the same size, the same clean bezel, and the same straightforward layout. What changes this time is the tone of the watch. The new model introduces a blue dial and matching bezel in what Tudor calls Tudor blue, while keeping everything else intact. It is not a redesign per se, but rather another take on a format that already works. The colour itself is rather saturated and vivid, and the brushed surface offers a lot of shifts in tone, the dial sometimes appearing almost purple.

With satin radial brushing, the dial’s surface is lightly domed. The layout stays familiar, with applied markers, snowflake hands, and a lollipop seconds hand, all filled with Super-LumiNova. Measuring 37mm, the case of the Black Bay 54 Blue 79000B has a thickness of 11.2mm and a 46mm lug-to-lug. For some contrast on the steel case, Tudor shows polished and satin finishes. 

The 60-minute unidirectional bezel in steel comes with a blue aluminium insert and stays clean as well, with no small minute markings, the kind you see on watches like the Submariner or even other Black Bay models. Here though, those markings are gone, which slightly changes how the watch looks, as we have already seen on the Black Bay 54 in black. With this design decision, the Black Bay 54 Blue 79000B also comes across as a bit less like a full-blown tool watch and a bit more relaxed overall. Water resistance remains at 200 metres, so even with its cleaner look, it still holds on to its dive watch credentials.

The Black Bay 54 Blue is powered by Tudor’s Manufacture Calibre MT5400, a movement produced by Kenissi that has already proven itself across the brand’s lineup. Running at 28,800 vibrations/hour and offering a 70-hour power reserve, this automatic movement is COSC-certified and uses a silicon balance spring, so it is built to be stable and reliable in everyday use. It also features stop-seconds for precise time setting. You can have it either on a three-link stainless steel bracelet or a rubber strap, both fitted with Tudor’s T-fit clasp.

The Tudor Black Bay 54 Blue 79000B is priced at CHF 3,650 or EUR 4,090 on rubber strap, and CHF 3,850 or EUR 4,320 on steel bracelet. It is now available and is part of the permanent collection. For more information, please visit tudorwatch.com.
