The Black Bay Fifty-Eight is a smaller-sized vintage-inspired take on the popular Tudor dive watch. Several versions of the compact BB have been presented since it was launched in 2018. On the occasion of Watches & Wonders 2021, two new materials join the collection. One is yellow gold, which we just saw on the Tudor Black Bay Fifty-Eight, and the other is silver, a rather unusual metal to craft dive watches. Meet the Tudor Black Bay Fifty Eight 925 ref. 79010SG.
As you would have understood by now, the 925 reference in the name of the watch refers to sterling silver (containing 92.5% by weight of silver and 7.5% of other metals). This is an unusual metal for a dive watch, and this is a first for a Tudor dive watch. However, the composition of the alloy used is kept secret by the brand. Its specificities aim at not affecting the appearance of the case. The brand also mentions that it stands out for its “unexpected incandescent brilliance“.
The use of silver is not the only modification to the 39mm case. For the first time this year (also on the 18k model), it features an exhibition caseback allowing you to admire the in-house calibre MT5400 in all its glory. That’s quite a cool upgrade as this has been implemented while preserving a 200m water-resistance.
The Tudor Black Bay Fifty-Eight 925 ref. 79010SG is also accentuated by its taupe colour dial, and its matching anodised aluminium bezel insert. The signature “snowflake” hands and the hour markers are fitted with luminescent material to ensure optimal legibility in all conditions.
The MT5400 calibre powering the watch shows the hours, minutes and seconds (with no date). The open caseback allows a view of the movement’s architecture and satin-brushed/sandblasted finishes. The monobloc rotor is openworked. Held under a traversing bridge, the balance ticks at 4Hz and its hairspring is amagnetic. The power reserve is of about 70 hours. The movement is a certified COSC chronometer, but Tudor regulates it within a stricter -2 / +4 seconds’ daily variation range.
The Tudor Black Bay Fifty-Eight 925 ref. 79010SG is worn either on a brown grain leather strap or taupe fabric strap with a silver band, both fitted with a 925 silver buckle. The price is set at CHF 4,100.
