Tudor has unveiled a fresh take on its beloved Black Bay 54 – meet the new Black Bay 54 “Lagoon Blue”. 
This latest release keeps the compact and classic proportions of the original but takes a bold step away from the vintage military aesthetic, embracing a modern and breezy summer vibe.
Housed in a 37mm stainless steel case with a thickness of 11.2mm, the new model retains the original’s wearable form factor. The standout feature here is the new grain-textured pale blue dial, paired with a mirror-polished steel bezel insert that replaces the more utilitarian black aluminum version on the original
. This aesthetic shift pushes the BB54 into lifestyle territory, offering a more versatile and fashionable take that still performs like a true diver.
The dial features dark blue printing and mirror-polished “Snowflake” hands and indices, all filled with Grade A Super-LumiNova for visibility. This refined finish aligns with the polished center links of the upgraded five-link bracelet, which adds to the overall elegance of the piece. 
The watch is water resistant to 200 meters and fitted with a domed sapphire crystal and solid screw-down caseback for durability.
Inside ticks Tudor’s MT5400 automatic movement, offering COSC certification, a 70-hour power reserve, and the brand’s stricter -2/+4 seconds per day tolerance. While it doesn’t carry METAS Master Chronometer status, its performance is still impressive and reliable.
The BB54 “Lagoon Blue” isn’t just a color swap-it’s a design statement. From the polished bezel to the updated bracelet, every change is geared toward making this watch more modern and accessible
. It’s no surprise Tudor is marketing this model as gender-neutral and vacation-ready rather than purely vintage-inspired. And although some purists may grumble at the continued use of Tiffany-adjacent hues, the popularity of light blue dials remains high across the industry.
Retailing at $4,350 USD, the new Lagoon Blue is just slightly more expensive than the black-dial BB54 on bracelet. For many, the aesthetic upgrade and elevated finishing justify the small price bump.
Whether you’re heading to the beach or just want something fresh for the summer, the Tudor Black Bay 54 “Lagoon Blue” delivers casual sophistication in a familiar but elevated package.
