Tudor Black Bay 58
The Black Bay 58 is Tudor's 2018 tribute to the 1958 Submariner reference 7924. Its 39mm steel case, COSC-certified MT5402 in-house movement, 70-hour power reserve, and 200m water resistance position it as the benchmark modern vintage diver under €4000.

The Black Bay 58 occupies a unique position: it is Tudor’s most-recommended single watch. Its 39mm diameter restores proportions closer to the 1958 original (vs the 41mm of the original 2012 Black Bay), and the slim 11.9mm case thickness fits under dress-shirt cuffs — rare for a 200m diver.
