Detailed Description
The Black Bay GMT “Pepsi” takes Tudor’s classic Black Bay dive‑watch language and adds a highly functional dual‑time complication, with the red and blue 24‑hour bezel clearly nodding to historic GMT icons while remaining distinctly Tudor thanks to the snowflake hand set and no‑crown‑guard case. The 41 mm steel case has a mix of brushed surfaces and polished case sides, giving it both tool‑watch robustness and some wrist presence, while the 200 m water‑resistance rating and screw‑down crown make it a genuinely capable sports watch.
Its domed opaline dial isn’t a flat white; it has a silvery‑white galvanic finish that gives a subtle metallic sheen and “polar” character under changing light. Applied markers, snowflake hour and seconds hands, and the red GMT hand are all filled with luminous material for strong low‑light legibility, with a date window at 3 o’clock completing the travel‑ready layout.
Inside, the MT5652 in‑house automatic movement offers approximately 70 hours of power reserve, COSC‑certified accuracy, and a true flyer‑style GMT function where the local hour hand adjusts independently in one‑hour jumps while home time and the red GMT hand remain anchored. This makes time‑zone changes quick and intuitive, and the movement’s silicon balance spring, robust construction, and bi‑directional winding deliver modern reliability and performance.
This configuration is supplied on the factory Tudor fabric (NATO‑style) strap with burgundy center stripe, which emphasizes the watch’s tool‑watch and travel character, while the included aftermarket strap with OEM deployant clasp gives you a more substantial, dress‑leaning option without sacrificing Tudor hardware quality.
Condition and Set
This 2025 Black Bay GMT Pepsi opaline is in good condition, with some fine hairlines visible on the high‑polished case sides under close inspection, consistent with normal careful wear. The bezel insert, dial, crystal, and case brushing present cleanly, and the straps remain in very nice condition.

Tudor Black Bay GMT Pepsi, opaline dial, ref. M79830RB‑0012
Original Tudor inner and outer boxes
Warranty card and booklets/manuals
Factory Tudor NATO‑style fabric strap
Additional aftermarket strap with OEM Tudor deployant clasp
