Black Bay Blue

The Tudor Black Bay Blue 79230B is a 41 mm stainless steel diver that pairs a black dial with the line's signature blue bezel and fabric strap aesthetic. It sits within the broader Black Bay family, which draws directly on Tudor's long history of producing professional dive watches from the 1950s onward. Powered by the in-house Cal. MT5602, the reference represents Tudor's commitment to vertical integration without departing from the collection's vintage-inspired character.

The Black Bay line was introduced in the early 2010s as Tudor's deliberate return to its dive-watch roots, reviving design cues — the "snowflake" hands, domed crystal, and riveted bracelet — from archival references. The Blue variant, distinguished by its blue bezel insert and matching accents, arrived in 2016 and has remained in continuous production, cementing its place as one of the line's most recognisable executions. The fitment of the Cal. MT5602, a COSC-certified movement developed entirely within the Tudor/Rolex group, marked a significant step for the brand's in-house manufacturing credentials. Over its production run the 79230B has been offered on both a steel bracelet and a fabric strap, broadening its appeal across different collecting tastes.
