WHAT WE LOVE:

The Tudor Black Bay GMT M79830RB offers everything enthusiasts love about the Black Bay line — vintage cues, tool-watch toughness, and modern specs — with the added functionality of a true GMT movement. Nicknamed the “Pepsi” for its red and blue anodised aluminium bezel insert, this reference is an unmistakable nod to mid-century jet-set watches while forging its own identity through Tudor’s distinct design language.

The 41mm stainless steel case is chunky, purposeful, and perfectly in line with the Black Bay family’s dive roots. It features a domed sapphire crystal, oversized crown, and a white opaline dial with snowflake hands, and applied luminous hour markers — all contributing to its vintage-inspired yet contemporary appeal. The red GMT hand tracks a second time zone via the 24-hour bidirectional bezel, and the watch features a quickset local jumping hour for easy timezone adjustment.

The rivet-style steel bracelet adds another layer of retro appeal while offering solid modern construction and comfort.

WHAT'S INSIDE:

Inside beats the Tudor Manufacture Caliber MT5652, an automatic movement with an integrated GMT function (not a modular add-on), boasting a 70-hour power reserve, COSC certification, and a silicon balance spring. With its column-wheel construction and proven durability, it reflects the same rugged ethos as the rest of the watch.
