Introduced in 2018 as an answer to collectors who found the original 41mm Black Bay too chunky, the 58 brought Tudor's dive watch back to 39mm and just under 12mm thick — proportions genuinely closer to the 1958 reference it takes its name from. A purpose-built in-house movement, developed specifically for this smaller case rather than shrunk from a larger caliber, delivers Master Chronometer-level accuracy after METAS testing across multiple temperatures and power states.

A unidirectional dive bezel with precise, confident clicks and Tudor's T-Fit clasp for on-the-fly bracelet sizing round out a watch that undercuts a comparable Rolex Submariner by more than half while sharing genuine 200m dive-watch DNA.
