When thinking about Tudor watches, most often than not, the one model that usually comes to mind is the emblematic Tudor Black Bay.

One particular Black Bay piece that has been gaining the attention of many enthusiasts and collectors is the Tudor Black Bay 58 Blue. With its vintage design and compact structure, the Tudor Black Bay 58 Blue pays tribute to the brand’s first-ever dive watch, the Tudor Submariner. In this article, we will be taking a closer look at this modern interpretation of the classic Tudor dive watch, along with its detailed specifications, its price, and some possible alternatives.

Stainless Steel Case

Starting with its case dimensions, the Tudor Black Bay 58 Blue has a case diameter of 39mm and a case height of 12.1mm, making it slimmer than most Black Bay models, which tend to come in 41mm and 43mm cases. With its toned-down size, wearers can easily and inconspicuously slide this watch under their cuffs, so it is not too bulky and obtrusive to wear. In addition, the Tudor Black Bay 58 Blue has a standard lug-to-lug measurement of 47.8mm and a lug width of 20mm, which makes it very convenient for wearers to swap out the Tudor Black Bay 58 Blue’s strap for some alternative options that better fit their tastes.

The case of the Tudor Black Bay 58 Blue is made out of high-quality stainless steel. It showcases finely polished sides and satin-finished lug hoods, providing an attractive combination of both duller and gleaming surfaces. Fixed on the right side of the watch is a screw-down crown bearing a raised image of the brand’s iconic rose emblem, which serves to enhance the watch’s aura of prestige.

On the underside of the Black Bay 58 Blue is a solid steel rear case that is also securely screwed down, preventing any moisture or dust from leaking in and damaging the watch’s inner mechanisms. With its screw-down crown and rear case, this timepiece has a total depth rating of 200m. As such, you can easily bring the Tudor Black Bay 58 with you into the shower, to the pool, or even to the beach.

Plan to go scuba diving with the Tudor Black Bay 58 Blue? You are sure to find its stainless steel unidirectional rotating bezel useful, in that case. Fitted on top of the bezel is a matte blue anodized aluminum insert, with silver gilded numerals and markers for the elapsed time scale. A luminescent pearl is positioned at the 12 o’clock marker, providing better legibility in deep waters.

The micro-knurling of this bezel is also quite nice, as it has fine tooth-like edges that provide wearers with a better grip compared to the Rolex Submariner. As such, you can easily pinch and turn the bezel, even if you are wearing a diving suit. When rotated, the bezel rings out with loud and chunky click noises, giving the timepiece more of a mechanical feel and ensuring that you will never lose track of the elapsed time.

Matte Blue Dial

As the source of the Tudor Black Bay 58 Blue’s name, the dial of this watch shows off a handsome matte blue surface with a silver-white chapter ring. The layout of this dial is both elegant and straightforward, with applique markers that take the form of large geometric shapes and the Black Bay collection’s signature snowflake hands. Much like the other Black Bay 58 models, the lume quality of the Tudor Black Bay 58 Blue is excellent. Its hour markers and handset are all generously applied with lume that allows it to glow bright green in the darkest environments, ensuring optimal legibility.

The Tudor signature, along with its depth rating and the COSC-certification of its movement, is also labeled on this dial in a neat white typeface that contrasts satisfyingly against the blue backdrop. When viewed in its entirety, this watch face evokes a memory of the similar-looking dials on the classic Tudor Submariner timepieces.

Domed Sapphire Crystal

Fitted on top of the Tudor Black Bay 58 Blue’s dial is a layer of domed sapphire glass. Known for its luxurious feel and unparalleled scratch resistance, the sapphire crystal is the most sought-after watch crystal for high-end timepieces. For context, sapphire crystals measure a “9” on the Mohs scale of mineral hardness. It is virtually impossible to scratch this watch glass and the only thing that could possibly damage it is diamond.

That said, there are some downsides to the use of sapphire crystal as well. Although sapphire crystal is incredibly scratch-resistant, it is more vulnerable to shocks and can be shattered by hard impacts, so be careful not to go knocking your Tudor Black Bay 58 Blue around. Sapphire crystal is also highly reflective, which could cause visual distortions when looking at the timepiece from certain angles. Unfortunately, much like Rolex, Tudor does not treat their watch crystals with anti-reflective coatings, so you might have some trouble reading your watch under very bright daylight.

Tudor Manufacture Caliber MT5402

The Tudor Black Bay 58 Blue is powered by the brand’s in-house Caliber MT5402. This is a self-winding mechanical movement with a bidirectional rotor system, allowing it to re-energize its own power supply as the wearer walks through kinetic energy. Held by 27 jewels, this Tudor caliber has a beat frequency of 28,800 vibrations per hour (4Hz) and a lengthy power reserve that can last up to 70 hours when fully wound. The Tudor MT5402 is also COSC-certified, providing an excellent accuracy rate of -4/+6 seconds per day. As long as this movement is kept in good condition, rest assured that you will not be having any reliability issues with the Tudor Caliber MT5402.

Stainless Steel Bracelet

Coupled with the Tudor Black Bay 58 Blue is a three-link stainless steel bracelet with beautifully polished sides and a satin-finished top surface. Its design replicates the riveted stainless steel bracelets seen on vintage Rolex and Tudor models. This bracelet is also equipped with a folding clasp and safety catch, along with removable links that allow wearers to size the bracelet to their preferred fit, so it will rest more comfortably and securely on their wrists. From a quality standpoint, the strap of the Tudor Black Bay 58 Blue is expertly done and easily matches the stainless steel bracelets used in Rolex timepieces.


As Rolex’s little sister, Tudor is known for offering timepieces with Rolex-level quality and aesthetics at much more affordable prices, and the same goes for the Tudor Black Bay 58 Blue. Typically, a brand-new Tudor Black Bay 58 Blue will cost you around $4,000 USD. A pre-owned version can be slightly cheaper, ranging between $2,800 USD to $3,800 USD in price depending on the seller and the condition of the watch.

First up is the limited edition Seiko Prospex Sumo (SBDC113) from the brand’s Japan Collection of 2020. Although it is much more affordable than the Tudor Black Bay 58 Blue, the design and quality of this Seiko diver does not deviate too far from it. 

This Seiko Prospex watch comes in a sturdy 45mm stainless steel case, which makes it a lot larger than the 39mm Tudor Black Bay 58 Blue. As you examine the timepiece from its sides, you will notice that its case has a nicely executed three-dimensional build. With its mirror-polished surfaces, this watch almost mimics the lustrous Zaratsu finishing that can be seen on Grand Seiko models. The screw-down crown positioned at 4 o’clock is also relatively large, with grooved edges so wearers will have an easier time turning and winding the crown.

Like the Tudor Black Bay 58 Blue, this watch has a stainless steel unidirectional bezel fitted with a glossy blue elapsed time scale insert that will come in handy when diving. This timepiece is also water-resistant up to depths of 200m, making it an excellent watch to use for anything from swimming to leisure diving activities. Turning the Seiko Prospex Sumo (SBDC113) around, you can find a solid steel caseback that is engraved with the Seiko Japan Collection 2020 logo.

Protected by a layer of sapphire glass, the dial of this Seiko watch boasts a gorgeous sunburst blue surface with a metallic finish. It is adorned with geometric hour markers and broad sword-shaped hands. In addition, the seconds hand is painted a bright yellow-green, which symbolizes the vitality of the ocean and adds a touch of vibrancy to this watch. Taking the place of the 3 o’clock marker is a rectangular date complication that is outlined with silver. Both the hands and markers of this dial are coated with Seiko LumiBrite. As many watch enthusiasts know, the lume quality of LumiBrite is impressive, even matching the grade of luminescence found in higher-end Swiss timepieces.

Underneath the blue Seiko dial is the brand’s automatic Caliber 6R35. Held together by 24 jewels, the 6R35 runs at a beat frequency of 21,600 vibrations per hour (3Hz), which is notably slower than the 28,800 vibrations per hour on the Tudor Black Bay 58 Blue’s MT5402. Fully wound, this Seiko movement can last for approximately 70 hours.
