Pre-owned Tudor Black Bay GMT ref 79830 (2021) is Tudor’s no-nonsense take on the travel watch, featuring a 41mm steel case with the brand’s familiar mix of polished and satin finishing. The watch has the classic tool-watch aesthetic with a domed black dial, large applied markers, and snowflake hand set. Everything is crisp, legible, and very Tudor. The burgundy-and-blue “Pepsi” bezel is a tribute of sorts to Tudor and Rolex GMT heritage, rendered here in matte anodized aluminum for a more vintage-adjacent aesthetic. Inside, the COSC-certified MT5652 delivers true traveler functionality with its built-in GMT architecture, allowing you to jump the local hour hand independently while the 24-hour hand tracks home time. With a 70-hour power reserve, 200 meters of water resistance, and Tudor’s engraved rose crown, it’s both rugged and refined. Shop Tudor Black Bay Collection
