Tudor "Lagoon Blue": New 2025 Release
Summer is in full swing, and with it comes Tudor’s boldest move yet: the Black Bay 54 “Lagoon Blue.”
This new release comes as a refreshing twist for Tudor, a brand typically known for its heritage-inspired, utilitarian divers. The Black Bay 54 “Lagoon Blue” builds on the success of last year’s Black Bay 54 introduction, but does so in a more playful fashion. It is not just a functional watch, but a seasonal piece designed to transport its wearer on a luxurious vacation—either imagined or real.
The watch (nicknamed “Blue Lagoon”) builds on the 37 mm Black Bay 54 model, which was originally launched in 2023 with a classic black dial. It won acclaim for its perfect proportions and faithful vintage styling. Now, Tudor has surprised enthusiasts with a summery look that retains the same retro dimensions and specs of the original, while injecting a bold shot of contemporary color and glamour.
From Vintage Grit to “Lagoon” Glitz
The design of the Black Bay 54 “Lagoon Blue” is a striking blend of old-school dive watch DNA and new-school flair. At first glance, your eyes are drawn to the dial – a cool aquamarine blue with a metallic sheen that Tudor likens to sunlit tropical waters.
Unlike the flat matte dials of many tool watches, this dial has a granular sand-textured finish that plays with the light, a detail rarely seen in Tudor’s catalog. The shade of blue itself is lighter and brighter than Tudor’s previous blues, a playful pastel that instantly channels summer fun.
It’s a daring move for a brand whose palette has historically stayed with blacks, burgundies, and darker tones.
Beyond the dial, the “Blue Lagoon’s” signature Tudor elements remind you that this is still a Black Bay. The iconic snowflake hands and the hour markers are applied and lumed, preserving the model’s functionality as a true dive watch. The Tudor shield logo sits at 12 o’clock. It also still features a unidirectional bezel made of stainless steel, with a mirror-polish.
Notably, though, the bezel lacks minute-marks—really solidifying it more as a fashion piece, while the model-exclusive jubilee-esque bracelet gives it a dressy feel.
Tudor M79000 Movement and Design
The case finish alternates between polished and satin-brushed surfaces, providing a quality feel in line with Tudor’s reputation. The watch features a sapphire crystal, offering scratch-resistance. Like any true dive watch, it has a screw-down crown and caseback to ensure water-tightness that is rated to 660 feet of depth resistance. This means not only is this piece fashionable, but functional for those deep diving or simply taking a dip in the pool.
At the heart of the Lagoon Blue 54 is the Manufacture Calibre MT5400, Tudor’s in-house automatic movement. The movement construction features a free-sprung balance and a silicon hairspring, which enhances its resistance to shocks and magnetism. All of this is hidden behind a solid steel caseback, but owners can trust that the finishing, while utilitarian, is top-notch for the price point.
Indeed, the craftsmanship and specs here are impressive for a watch retailing for $4,350 USD.
In terms of manufacturing pedigree, Tudor’s use of a manufacturing caliber at this price is still relatively uncommon in the industry. Many competitors in the ~$4k range use modified off-the-shelf movements, whereas Tudor (with Rolex’s backing) offers a high-grade in-house movement. The “Blue Lagoon” delivers a lot of watch for the money: chronometer precision, 600 feet robustness, a sophisticated micro-adjust clasp, and a unique design from a storied brand.
Tudor has essentially married tool-watch substance with fashion-forward style in this piece, and done so while maintaining fine Swiss craftsmanship. For buyers, that means you’re getting a watch that is both a conversation starter and a reliable daily companion.
In short, the Lagoon Blue may look like a leisure accessory, but it’s built to Tudor’s professional diving watch standards through and through – something the brand was careful not to compromise even as it experimented with aesthetics.
Tudor Black Bay 54 Lagoon Blue Price
This special edition isn’t a numbered limited-run. In fact, Tudor has confirmed the “Blue Lagoon” as a regular production model available at boutiques now. However, initial availability could be somewhat scarce due to high demand. The “Blue Lagoon” is already the talk of online forums and watch media, suggesting that this may be the next must-have piece of the year.
The Black Bay Fifty-Eight Blue, which was released in 2020, received similar hype and was also hard to get your hands on. We could see a similar short-term scarcity before Tudor ramps up supply. But the demand is no doubt largely thanks to the seasonal color.
It’s safe to say the “Blue Lagoon” will command strong interest on the secondary market initially. Early adopters who miss out at retail might be willing to pay a premium to get one immediately. This watch is likely to go for around $7,000 on the secondary market. However, this resale hype might be short-lived once the watch is more readily available on the market. So in the long term, one can expect prices to stabilize around retail, or only slightly above if the model remains super popular.
Unlike certain Rolex sports models that perpetually trade over list price, Tudors more often settle at or even a bit below MSRP once the hype settles.
In effect, the Blue edition carries a built-in exclusivity through its unique aesthetic. With that being said, there are already waitlists forming to get your hands on this piece!
Final Thoughts – Significance, Appeal, and the Legacy of the “Lagoon Blue”
Tudor’s Black Bay 54 “Lagoon Blue” is more than just a new color variant – it’s a statement about the shift of the luxury sports watch market (and Tudor itself). Culturally, this release is significant because it shows a major Swiss brand stepping slightly outside of its comfort zone to cater to a new clientele.
Traditionally, dive watches have been marketed in a very masculine, tool-oriented way. Here, Tudor flips the script: by making a petite 37 mm diver with a shiny bezel and a pastel dial that is explicitly marketed in a summery, lifestyle context. The brand is clearly extending an olive branch to style-conscious consumers, but especially women.
The 37 mm size was already inviting to anyone with a smaller wrist, now the color and sparkle adds a feminine flair. It’s not that men won’t wear this watch (many absolutely will), but it’s notable that a Swiss tool-watch icon like Tudor is primarily catering to a female audience—something practically unheard of for a dive watch until now.
This marks a shift in the industry’s thinking, an acknowledgment that the future of watch enthusiasm is broad and inclusive, and that women are not limited to watches explicitly made for ladies, that are stereotypically adorned with diamonds or quartz movements.
The “Blue Lagoon” is unisex in capability yet slightly feminine in flair, striking a fascinating balance that is likely to be a lasting hit—or even a cult classic that marks a shift in Tudor’s willingness to evolve.
In summary, Tudor’s Black Bay 54 “Blue Lagoon” moment combines substance and style in a way few releases do. It appeals to the dreamer (with its promise of hammocks and lagoons) and the pragmatist (with its solid specs and fair price) alike. Time will tell if it becomes a lasting icon but, for now, it certainly has made a splash.
