🔎 CASE NOTES

The Tudor Black Bay GMT "Pepsi" has become one of the defining travel watches of the modern era. Introduced in 2018, it brought Tudor's renowned Black Bay design language together with a true GMT complication powered by the brand's first in-house GMT movement. The result is a watch that offers outstanding mechanical capability, vintage-inspired styling, and exceptional everyday versatility.

The signature blue and burgundy anodized aluminum bezel has quickly become synonymous with the model, earning the familiar "Pepsi" nickname among collectors. Combined with Tudor's snowflake hands, domed matte black dial, and robust 41mm case, the watch delivers strong wrist presence while remaining equally at home in the office or while crossing time zones.

This 2021 example is presented in excellent pre-owned condition and includes its box, papers, and warranty card. The stainless steel bracelet is currently sized to fit approximately a 7.75-inch wrist.
