Unveiling the new Tudor Black Bay Fifty-Eight “NAVY BLUE’ Diver

Unveiling the new Tudor Black Bay Fifty-Eight ‘Navy Blue’ 79030B

Since the introduction of the wildly popular vintage-sized Black Bay Fifty-Eight diver in 2018 at Baselworld, the Tudor brand has been wanting to explore the new, more compact iteration of the modern classic Black Bay Fifty-Eight diver in more variations.

The new Tudor Black Bay Fifty-Eight “Navy Blue”, reference 79030B, is a 39mm stainless steel case that maintains the compact and balanced proportions of its black dial sibling.  With a classic slab-sided diver shape and large unguarded screw-down crown, the Black Bay Fifty-Eight displays its brand DNA front and center, with just enough changes to the original design to create a modern classic in its own right.  Where the “Navy Blue” sets its own course, naturally, is the matte blue aluminum bezel.  Keeping the same unmistakable Submariner-style diver insert as previous models, the new color helps to soften a design that can at times veer too sharply angular while tying back to the classic “Blue Snowflake” Tudor Submariner.

THE INSPIRATION

Tudor’s involvement with the French Navy (Marine Nationale) not only helped shape the development of their Submariner as a true military-issued dive watch, but legit signed examples of references like the late-60s 7016/0 and the mid-70s 9041/0 are seriously collectible and thus offer an ideal reference for a vintage-inspired watch like the Black Bay Fifty-Eight. The entire range of the brand’s iconic “Snowflake” Submariner is commonly referred to as the “MN.” While MN Tudors came in both black and blue, Tudor picked the blue variant as inspiration for this 2020 model

THE MOVEMENT

This new Black Bay Fifty-Eight with a lovely, rich blue used for both the dial and the bezel is powered by the in-house manufacture Calibre MT5402 automatic movement. This COSC chronometer-certified powerplant offers a handful of impressive technical innovations, including a variable inertia balance with a silicon balance spring, Rolex Microstella-style free-sprung, and adjustable mass balance – very much a Rolex technology movement. These come together to provide not just chronometer grade accuracy, but a 70-hour power reserve at a relatively high 28,800 bph beat rate.

THE BRACELET

The most classical choice is the stainless steel rivet oyster bracelet, with some of the best fit and finish in its price class, but our only complaint here would be that they still haven’t included the “Quick adjustment” on the clasp. For those of you looking to accentuate the new blue colorway, there are two alternatives. The first is a single pass fabric strap in jacquard woven navy blue, featuring an eye-catching complementary central stripe in silver. The more unorthodox option looks at first balance to be medium blue suede. On closer inspection, however, this strap is made from a synthetic “soft touch” material with a consistency not unlike flannel.

While it’s far from an unexpected addition to the brand’s lineup, the Tudor Black Bay Fifty-Eight “Navy Blue” helps to extend one of its hottest lines in a new and undoubtedly popular direction.  The Tudor Black Bay Fifty-Eight “Navy Blue” is available now through authorized dealers.
