Black Bay 41

The Tudor Black Bay 41 (ref. 79540) is a stainless steel sport watch that brings the iconic Black Bay silhouette to a 41 mm case diameter, sitting between the long-established 41 mm and smaller 36 mm variants of the line. Available in both black and blue dial configurations, it carries the hallmark Black Bay design cues — the distinctive "big crown," domed crystal, and snowflake hands — that trace their visual lineage to Tudor's mid-twentieth-century dive references. Powered by the reliable ETA Calibre 2824, the 79540 represents a period in the Black Bay's evolution before Tudor's broader transition to fully in-house movements across the collection.

The Black Bay line was revived by Tudor in the early 2010s as a modern reinterpretation of its vintage dive watch heritage, quickly becoming the brand's most recognized contemporary collection. The reference 79540 was introduced in 2019, offering collectors the full 41 mm Black Bay experience with the proven ETA Cal. 2824 at its core. Production of the 79540 ran through approximately 2023, a period during which Tudor was progressively rolling out its proprietary MT5602 movement across the broader Black Bay range. The reference thus occupies a distinct and transitional chapter in the Black Bay's ongoing story.
