Silver Treasure: Testing the Tudor Black Bay Fifty Eight 925 (1)

Tudor is one of the few brands whose demand has increased significantly in recent years. This is mainly due to the attractiveness of their models, which certainly include the Black Bay and the smaller version released in 2018, the Black Bay Fifty-Eight. The version tested here was launched in 2021 in a silver box with a taupe-colored bezel.

The name Fifty-Eight refers to 1958, the year Tudor launched its first diving watch. Divers in the French Navy approached the brand to create an ideal diving watch designed specifically for their needs and as a result, Tudor became the preferred supplier for French combat divers. The case size of 39 mm corresponds to its historical predecessor. The rotating bezel and smaller dial give the watch an understated look that's in line with current trends.

The vintage look is enhanced with a scratch-resistant domed sapphire crystal replacing the original acrylic crystal. The dial also has a slight retro-style curvature. Narrow shoulder straps and typography on the rotating bezel also hint at the Tudor history. Even the date has been omitted for a more historically accurate print. Traditional "snowflake" hands have been used at Tudor since the late 1960's.

Unlike previous models, the 2021 Black Bay Fifty-Eight 925 has a taupe bezel and dial. The color, which can also be seen as a faded black, goes well with the vintage design. On the other hand, the greyish shade of brown is also a modern trend color, especially in today's interior design.

A secret silver league
The taupe color harmonises well with the warm tones of the 925 silver case. The designation "925" means that the case is made of 92.5% silver and 7.5% other materials. Ordinary sterling silver also contains this amount of pure silver, with the remainder being mostly copper, giving the metal a reddish hue. However, sterling silver tends to tarnish, as anyone who owns sterling silver cutlery can attest. It is the result of a chemical reaction between the silver and sulphur-containing substances in the air, which causes the silver to darken over time. To avoid this, Tudor used a different alloy touted as non-staining. Although Tudor didn't reveal the other materials, there are known alloys containing palladium and germanium that prevent tarnishing and can even be hardened. The hardness of this material is even more comparable to gold than to steel. The Tudor case shines with a brilliant shine and is warmer in color than stainless steel or platinum.

While the aluminum dial on the scuba bezel isn't as scratch-resistant as a ceramic alternative, its matte finish better suits the watch's vintage look. Overall, our test watch convinces with an attractive design and very harmonious colors.

Thankfully, functionality hasn't been sacrificed for design here. Large luminous markers and a generous application of luminous material on the hands ensure excellent legibility day and night. The screw-down crown feels good in the hand; decoupled from the winding mechanism to reduce wear. The inclusion of a hack mechanism as well as no date display and no pulled-out crown position for this function make time setting easy. The unidirectional rotating bezel rotates in one-minute increments and is easy to hold and rotate thanks to its wedge-shaped rim. Its click operation feels almost as rich as that of a Rolex watch. A luminous marker shows dive time even in the dark. Thanks to the case, which is water-resistant up to 200 meters, the Black Bay is really suitable for diving, at least with the NATO fabric strap.

strap options
Our test watch came with an attractive textured dark brown leather strap with contrast stitching and a rubber finish that extends the life of the strap. A stylish and practical brushed silver pin buckle to match the case. We like the look of the taupe-colored fabric strap with a silver middle strap better than the leather strap, as it doesn't taper as much towards the clasp. However, the fabric strap obscures the case back, which is particularly unfortunate here as this is the first regular production Black Bay model with a transparent window revealing the automatic caliber MT5400. The caliber is made by the movement manufacturer Kenissi, who also supplies Chanel, Breitling, Fortis and other watch brands.

A robust caliber
The movement has sturdiness and precision. Its impressive height of 4.99 mm makes it robust in order to avoid malfunctions even with the smallest tolerance fluctuations that may have occurred in production. The balance is also ensured by a full bridge instead of just one side. The silicone spiral maintains centricity as it is resistant to deformation from impact or other disturbances. Other high-quality features of this manufactory movement are the extended power reserve of 70 hours and the free spring balance with four adjusting screws - the gear setting is not, as with most ETA calibers, done by changing the active spring length. Movement detailing is modest, but the rotor is skeletonized with a sunray finish and Tudor engraving.

Accuracy of rate accuracy is certified by COSC, the official Swiss chronometer testing institute, where Tudor sends most of its movements for testing (the MT5602-1U used in the new Black Bay Ceramic comes with a Master Chronometer Certificate supplied by METAS). Rate results are guaranteed to stay within a range of -4 to +6 seconds per day, among other criteria. The results displayed in the electronic timing confirm this accuracy: the values ​​at different positions remain very close to each other, while the average deviation was almost perfect: only +1 second per day. On the wrist we saw a gain of 2 seconds per day, probably due to the fact that the watch was 'dial' at night, a position that showed the biggest gain of +5 seconds.

The technical characteristics of the Tudor Black Bay Fifty-Eight 925 put it at the top, and its execution and finish set it apart from the rest. The design mix of retro elements and warm gray tones knows how to inspire, and the surcharge of 950 euros compared to the basic price of the silver version feels moderate and reasonable.
