Heritage Narrative
The Black Bay collection has become Tudor’s modern cornerstone, combining vintage-inspired design with contemporary watchmaking. In 2024, Tudor introduced the Black Bay 58 GMT, expanding the beloved 39 mm diver into a true traveler’s companion. Compact, versatile, and robust, it blends the vintage proportions of the Black Bay 58 with the practicality of a GMT complication.

This July 2025 example, reference 7939G1A0NRU, features a 39 mm stainless steel case with black dial and sapphire crystal, paired with a steel bracelet. Powered by Tudor’s latest manufacture GMT calibre, it offers chronometer-certified accuracy, a robust power reserve, and independently adjustable local hour hand. Offered unworn and accompanied by its full set of box and papers, it represents the cutting edge of Tudor’s celebrated Black Bay line.
