Tudor Black Bay 58 Blue: The Summer’s Biggest Release
The rumors have swirled for months, circulating through every enthusiast forum and Instagram feed, but the wait is finally over. Today, we can officially confirm that the Tudor BB58 Blue has arrived, and it is every bit the "Blue Sub" successor we have been dreaming of. As we step into the heat of June 2020, the horological world has been searching for a spark of excitement, and Tudor has delivered a lightning bolt. This isn't just a color change; it is the refinement of a modern icon that solidifies the Black Bay 58’s position as the most relevant dive watch on the market today.
When the original Black Bay 58 launched in 2018 with its black dial and gilt accents, it recalibrated our expectations for what a vintage-inspired diver could be. It was the "Goldilocks" watch—not too big, not too thick, and dripping with 1950s charm. However, for a vocal segment of the community, the "fauxtina" (artificial patina) was a polarizing choice. The new Tudor BB58 Blue addresses this by stripping away the warmth of the gilt for a cold, clinical, and stunningly sharp "Navy Blue" aesthetic that feels both contemporary and historically significant.
The Aesthetics of Navy Blue
At first glance, the Tudor BB58 Blue is a masterclass in color theory. Tudor refers to this shade as "Navy Blue," and it is a distinct departure from the "Midnight Blue" seen on the larger 41mm Black Bay models. While the Midnight Blue often appears almost black in low light, this navy remains resolutely blue. It features a matte finish that absorbs light, preventing distracting reflections and ensuring that the focus remains on the legibility of those iconic snowflake hands.
Unlike its predecessor, the Tudor BB58 Blue ditches the cream-colored lume in favor of crisp, white Super-LumiNova. This change completely transforms the character of the watch. Where the black version felt like a heritage piece found in a dusty drawer, the blue version feels like a modern tool watch that just happens to have perfect proportions. The silver-toned printing on the dial and the silver-colored scale on the anodized aluminum bezel insert create a monochromatic harmony that makes the watch incredibly versatile. Whether you are wearing it as a high-end beater for a weekend at the coast or as a desk diver under a linen shirt, the blue hue fits the summer vibe perfectly.
Perfect Proportions: The 39mm Case
The magic of the Tudor BB58 Blue lies in its case dimensions. In an era where many dive watches have bloated to 43mm or 44mm, Tudor’s decision to stick with the 39mm diameter is a win for enthusiasts. With a thickness of just 11.9mm and a lug-to-lug measurement of approximately 47mm, it sits low and tight on the wrist. It offers that elusive "vintage feel" without the fragility of an actual vintage timepiece.
The finishing remains top-tier for this price bracket. You’ll find high-polished flanks contrasted against satin-brushed lug tops, with a sharp, polished bevel (or chamfer) running the length of the case. This is a nod to the big-crown Tudor Submariners of the late 1950s, specifically the reference 7924. On the wrist, the Tudor BB58 Blue feels balanced and substantial without being cumbersome—a rare feat for a watch rated to 200 meters of water resistance.
Technical Specifications
Behind the stunning blue dial beats a powerhouse of modern engineering. The Tudor BB58 Blue is powered by the Manufacture Calibre MT5402. This movement was designed specifically for the medium-sized Black Bay range, ensuring that the proportions of the watch weren't compromised by a movement that was too large or too thick.

Performance and the MT5402 Movement
The MT5402 is a "weekend-proof" movement, boasting a 70-hour power reserve. This means you could take the watch off on Friday evening and pick it up on Monday morning without needing to reset the time. It features a non-magnetic silicon hairspring and is COSC-certified, though Tudor is known for regulating these movements to even tighter tolerances than the official -4/+6 seconds per day.
For the purists, the lack of a date window is a blessing. It preserves the symmetry of the dial and ensures that the Tudor BB58 Blue remains a dedicated tool watch. The winding action of the crown is smooth and tactile, lacking the "grittiness" often found in entry-level luxury divers. When you unscrew the crown to set the time, there is a reassuring solidity to the stem that inspires confidence.
Bracelet and Strap Options
Tudor is offering the Tudor BB58 Blue on three distinct mounting options. The most popular will undoubtedly be the "rivet" stainless steel bracelet. While some collectors find the faux-rivets on the sides of the links a bit unnecessary, there is no denying the comfort and quality of the construction. It tapers elegantly to the clasp, which features the ceramic ball bearings that make the Tudor "click" so satisfying.
For those looking for a more casual look, the blue fabric strap—woven on 19th-century Jacquard looms by the Julien Faure company in France—is a fantastic choice. It is widely considered the best fabric strap in the industry. Finally, there is a new "soft touch" material that feels like a mix of flannel and rubber, providing a modern, sporty alternative for those who find steel too heavy for the summer heat.
Is This Your Next Grail?
In the context of the current market, the Tudor BB58 Blue occupies a unique space. It offers the heritage and prestige of the Rolex family tree but with a design language that feels more adventurous and accessible. For many, this will be a grail watch—an attainable piece of high-end watchmaking that can be worn every single day without fear.
The blue dial is not just a trend; it is a tribute to the "Tudor Blue" watches used by the French Marine Nationale in the 1970s. By combining that historical DNA with the modern MT5402 movement, Tudor has created a watch that appeals to both the vintage nerd and the first-time luxury buyer. If you’ve been waiting for a sign to add a blue diver to your collection, this is it.
Final Thoughts on the Tudor BB58 Blue
The Tudor BB58 Blue is a triumphant release that perfectly captures the mood of Summer 2020. It takes the best-selling silhouette in the Tudor catalog and refreshes it with a colorway that feels timeless rather than trendy. By opting for a clean, white-lume aesthetic and a rich navy blue, Tudor has moved away from the "vintage reissue" niche and into the realm of the modern classic.
Whether you are capturing a wristshot against the ocean or simply enjoying the way the light hits the domed sapphire crystal at your desk, the Black Bay 58 Blue delivers an experience that punches far above its price point. It is balanced, technically impressive, and aesthetically flawless. Tudor has once again proven that they aren't just Rolex's younger sibling—they are a powerhouse in their own right, defining the current era of the luxury sports watch.
