The Tudor Black Bay 58 GMT M7939G1A0NRU-0003 represents a sophisticated expansion of the Black Bay 58 line, introducing a dual-time complication while preserving the compact proportions that define the collection. Crafted in a 39mm stainless steel case with polished and satin finishes, this model maintains a highly wearable profile while adding visual depth through its black and burgundy bidirectional 24-hour bezel. The domed black dial, accented by gilt hour markers and signature snowflake hands, delivers strong legibility while reinforcing Tudor’s vintage-inspired design language.
At its core, the watch is powered by the Manufacture Calibre MT5450-U, a self-winding movement certified as a Master Chronometer by COSC and METAS. This ensures exceptional precision, resistance to magnetic fields, and consistent performance under real-world conditions. The integrated GMT function allows tracking of a second time zone, while the movement delivers a power reserve of approximately 65 hours and features a bidirectional rotor system for reliable everyday use.
Engineered for versatility, the Black Bay 58 GMT offers 200 meters of water resistance, a screw-down crown, and a domed sapphire crystal for enhanced durability. The stainless steel bracelet is equipped with Tudor’s T-fit clasp, allowing quick micro-adjustments without tools for optimal comfort. Altogether, this model combines travel functionality, heritage aesthetics, and modern chronometric performance, making it one of the most balanced and versatile watches in the Tudor lineup.
