The Tudor Black Bay 58 GMT reference M7939G1A0NRU-0001 is an exceptional dual-time sports watch that skilfully blends vintage-inspired design cues with modern mechanical innovation. Part of the highly regarded Black Bay 58 family, this model is crafted for watch enthusiasts and frequent travellers who value both timeless style and superior functionality.
This certified pre-owned luxury watch is offered in very good condition and is supplied as a full set, complete with its original Tudor box and papers. The 39 mm stainless steel case strikes a perfect balance between classic proportions and contemporary versatility, making it comfortable for everyday wear while still delivering a strong wrist presence. The satin-brushed and polished finishes enhance both durability and aesthetic appeal.
The deep black dial is adorned with gilt accents and Tudor’s signature “Snowflake” hands, ensuring excellent legibility in all lighting conditions. A bidirectional 24-hour bezel with a black and burgundy aluminium insert frames the dial, enabling intuitive second time-zone tracking — a key feature for global travellers. The domed sapphire crystal protects the dial and adds to its resilience against daily wear.
Powering this timepiece is the Tudor Manufacture Calibre MT5450-U automatic movement, recognised for its robustness, precision and extended autonomy. This movement delivers an approximate 65-hour power reserve and includes COSC certification for chronometric performance. The GMT function allows independent setting of the local hour hand without stopping the watch, enhancing convenience for frequent time-zone adjustments.
