The Tudor Heritage Black Bay is an iconic dive watch that blends vintage aesthetics inspired by historical Tudor models from the 1950s-1980s with modern watchmaking. Initially launched in 2012, it featured an ETA-based movement. In 2016, the collection was updated with Tudor's in-house Caliber MT5602, which is COSC-certified and boasts a 70-hour power reserve. The watch is distinguished by its 'snowflake' hands, a large screw-down crown with the Tudor rose emblem, and a domed sapphire crystal. The 41mm stainless steel case ensures water resistance up to 200 meters and is available with various bezel options (red, blue, black) and strap choices (steel, leather, or fabric).
