The TUDOR Black Bay 54 “Lagoon Blue” is one of the most exciting additions to the Black Bay collection, blending vintage-inspired design with a vibrant aesthetic. Drawing inspiration from TUDOR’s first divers’ watch, the Oyster Prince Submariner reference 7922 released in 1954, the “Lagoon Blue” model combines proportions that enthusiasts love with a distinctive dial that feels perfectly suited to modern lifestyles.

Designed around a compact 37mm case, the model delivers exceptional versatility on the wrist. Its size stays true to the original proportions of the 1954 dive watch whilst appealing to those seeking a more wearable, balanced sports watch. Finished with a combination of polished and satin-brushed surfaces, the case offers a refined appearance without losing the robust character that defines the Black Bay collection.
The watch’s standout feature is undoubtedly its “Lagoon Blue” dial, described by TUDOR as evoking azure waters, bright sunshine and white sand beaches, creating a strong sense of escapism and adventure. Unlike traditional models, the dial also features a unique sand-textured finish that catches the light beautifully, adding depth and visual interest from every angle.

This fresh colourway gives the Black Bay 54 an entirely new personality. While retaining the iconic “Snowflake” hands and highly legible hour markets that have become signatures of TUDOR dive watches, the “Lagoon Blue” dial feels lighter, more playful, and distinctly contemporary.
As impressive as the exterior may be, the Black Bay 54 “Lagoon Blue” is every bit as capable technically. Powered by TUDOR’s Manufacture Calibre MT5400, a COSC-certified self-winding mechanical movement developed to deliver excellent reliability and precision, the model offers a “weekend-proof” 70-hour power reserve. For everyday wear, this means that the watch can be comfortably set aside on Friday and still be running when picked up again on Monday.
Presented on a five-link stainless steel bracelet with TUDOR’s practical “T-fit” clasp, allowing the wearer to quickly and easily adjust the fit without the need for tools, the Black Bay 54’s screw-down crown, domed sapphire crystal and 200m water resistance provide the functionality and robustness you’d expect from a professional-grade sports watch.
For those looking for a luxury dive watch that offers versatility, character and proven performance, the Black Bay 54 “Lagoon Blue” is an exceptional choice, capturing the spirit of summer while delivering the quality and craftsmanship TUDOR has become renowned for worldwide.
