Tudor GMT

The TUDOR Black Bay 58 GMT reference M7939G1A0NRU-0001 is a refined travel watch that combines vintage-inspired dive-watch aesthetics with modern chronometer-grade engineering. Housed in a 39mm stainless-steel case with polished and satin-brushed surfaces, it features a striking black dial accented by gilt hour markers and Tudor’s signature Snowflake hands, framed by a bidirectional 24-hour black-and-burgundy aluminium bezel that has earned the model the nickname “Coke GMT.” Inside beats the manufacture Calibre MT5450-U, an in-house automatic movement certified by both COSC and METAS, offering exceptional accuracy, anti-magnetic resistance up to 15,000 gauss, and a robust 65-hour power reserve. The integrated GMT function allows tracking of multiple time zones, making it ideal for frequent travelers, while the screw-down crown, domed sapphire crystal, and 200-metre water resistance preserve the watch’s serious diving credentials. Completing the package is a vintage-inspired three-link rivet-style steel bracelet fitted with Tudor’s T-fit micro-adjustment clasp, delivering a blend of comfort, practicality, and retro charm that positions the Black Bay 58 GMT as one of the most versatile luxury sports watches in Tudor’s current lineup.
