Tudor’s best-selling timepiece is back with another update in 2018. Despite their varied releases it seems the market was seeking a smaller option. Introducing the “Tudor Black Bay Fifty-Eight” in a 39mm sized case.

Since its introduction in 2012 the “Black Bay“ by Tudor has in a way redefined the brand. Beginning with that burgundy bezel model unveiled at Baselworld, which managed to encapsulate a modern-sized but historically-inspired dive watch in one piece. Crafted with contemporary specifications and a vintage design dating back to 1954. And now in recent history their “Black Bay” model has been by far the brands best-seller. It has served to reinvigorate and recast Tudor as a viable and desirable option when it comes to horology needs.

The 39mm case is made of stainless-steel with a polished and satin solid case back. Mounted to the watch is a rotatable steel bezel with a black insert that features a 60-minute scale.

The red triangle we see on it is a direct reference to the first generation of Tudor diver watches, which also included that subtle highlight.

Equipped with a satin-brushed steel screw-down crown that features the Tudor rose logo engraved to it. Finally this timepiece is topped by a domed sapphire crystal that assists with water-resistance on this watch reaching up to 200 meters (660 feet).

This is a slightly smaller case diameter compared to the previous “Black Bay” releases, such as the updated 2016 model line that oscillated from 41 to 43mm sized versions, as you can read about and take a better look at here.

Or, even the more recently launched “Tudor Black Bay GMT” (Ref#: 79830RB) with an almost “Pepsi bezel” measured in at 41mm, as you can closer observe by visiting the Baselworld 2018 release review we wrote up here.


So Tudor also had to develop a smaller version of the existing MT5602 movement, which has powered the majority of the three-hand watches on the “Black Bay” model line. But, despite reducing the diameter the MT5402 movement was able to retain all its key features, it was modeled off of including: a variable inertia balance wheel, traversing two-point balance bridge and a silicon non-magnetic balance spring.

Time is exhibited on a black domed dial with a triangular, some rectangular and round hour index markers; followed by a railroad-motif of gold colored minute index markers circling the dial.

Comes equipped with the angular central hands known as “snowflake” hands, just like the one’s seen on the brand’s 1969 catalog model. And the central hands along with all the hour index markers have been given a luminescent coating, for an enhanced legibility.
