Introduced in 2017, the M79350 combined the Black Bay's dive-watch architecture with a motorsport-inspired chronograph, creating one of Tudor's more distinctive modern references.\u003c\/p\u003e\n\u003cp\u003eThe monochromatic \u003cstrong\u003eblack dial, steel tachymeter bezel, and contrasting silver chronograph registers\u003c\/strong\u003e give this generation a noticeably different personality from the later ceramic-bezel models. At 41mm it has substantial wrist presence, while retaining the familiar snowflake hand and rugged Black Bay design language.\u003c\/p\u003e\n\u003cp\u003eMore important is what sits inside. Tudor's \u003cstrong\u003eMT5813\u003c\/strong\u003e is a COSC-certified automatic chronograph developed from Breitling's B01 architecture and modified to Tudor specifications. It uses a column wheel and vertical clutch and provides approximately \u003cstrong\u003e70 hours of power reserve\u003c\/strong\u003e. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eCase #604 is presented in \u003cstrong\u003eexcellent pre-owned condition\u003c\/strong\u003e.

Tudor took the architecture of Breitling's respected B01 chronograph and adapted it with its own regulating system and finishing.

The engraved steel tachymeter bezel and original dial architecture distinguish it immediately from the later M79360N generation.\u003c\/p\u003e\n\u003cp\u003eFor collectors who prefer the original execution—or simply want a Black Bay Chronograph that isn't one of the now-familiar Panda configurations—the M79350 offers something increasingly different.\u003c\/p\u003e\n\u003ch2\u003e🧾 FROM THE CASE FILE\u003c\/h2\u003e\n\u003cp\u003eTudor Black Bay Chronograph Ref.

The steel tachymeter bezel and original dial configuration give it a character the later Panda generation left behind, while the MT5813 provides genuinely impressive mechanics underneath.
