Tudor Black Bay Fifty Eight Bronze 79012M

This Black Bay Fifty-Eight Bronze is indeed rather close in style and proportions to all other members of the BB58 family. No surprises here. If you like a well-proportioned, compact dive watch with vintage appeal, you’ll be served. The BB58 is basically an ode to classic dive watches from the 1960s with a 39mm diameter, a rather contained height of 11.9mm (which is far less than a classic Black Bay, at about 14.8mm), and an oversized crown without guards. Add to that a domed sapphire crystal, shaped just like an old plexiglass and a thin bezel with classic graduation, and you end up with a watch that oozes old-school diving instrument – for instance, the famous reference 7924 Big Crown, the first Tudor to be waterproof to 200 metres, presented in 1958. Lug-to-lug measurement is 48mm, which could seem rather large on paper, but actually wears pretty well due to the curvature of the case.
