Tudor’s New Black Bay 54 ‘Lagoon Blue’: A Summer-Ready Refresh

Tudor has just unveiled a bright new take on its 37mm dive watch: the Black Bay 54 ‘Lagoon Blue’. Mechanically, nothing has changed—it still runs on the MT5400 movement with 200 metres of water resistance—but the new dial, bezel and bracelet give it a distinctly different character.

Dial and Bezel: Subtle Changes, Big Impact

The dial sits somewhere between turquoise and pale ice blue, with a textured, sandy finish that adds depth without veering into gimmick territory. It’s paired with a mirror-polished aluminium bezel insert featuring recessed, grainy numerals and indices. Together, they make for a watch that’s clean, crisp and—yes—a little playful.

Personal take: I’d have preferred a brushed bezel. It would lean more tool-watch than dressy. But in fairness, the polished finish does create a sharp contrast that complements the dial well.

Now on a Five-Link Bracelet

This is the first time the Black Bay 54 has been offered on Tudor’s five-link bracelet—the same one seen on recent releases like the Black Bay Chrono Flamingo Blue, Chrono Pink, and METAS-certified Black Bays. The polished centre links offer a touch more flash, while the overall fit feels a bit more refined. The bracelet is equipped with Tudor’s T-Fit clasp for quick, tool-free adjustment.

Combined with the dial and bezel, this new bracelet gives the BB54 a fresh energy. It still holds serious dive specs, but now with a more relaxed, summer-ready feel.

Not a Limited Edition—But Possibly a Tougher Find

The ‘Lagoon Blue’ isn’t a numbered limited edition like the Black Bay Chrono Carbon 25, but it does fall under Tudor’s “Daring Watches” collection—home to both exclusive and low-production models. That’s no guarantee of rarity, but it’s likely this version won’t be as widely available as the standard black-dial BB54.

The UK retail price is £3,330, a touch higher than the standard BB54 on a bracelet (£3,200) or strap (£3,030).

Final Thoughts

I haven’t seen it in person yet, but judging by the official images and specs, this is the version of the BB54 I’d pick. The dial and bezel feel genuinely new—rather than recycled—and the five-link bracelet gives it a more polished daily-wear appeal. With the T-Fit clasp, it’s as practical as it is good-looking.

This isn’t just a seasonal colourway—it’s a subtle but meaningful evolution of the BB54. What do you think: would you choose the ‘Lagoon Blue’ over the black-dial original? And where do you stand on polished bezels for dive watches?
