Tudor Black Bay Fifty-Eight GMT

Tudor Black Bay 58 GMT Ref. M7939G1A0NRU-0001

The Tudor Black Bay 58 GMT with reference M7939G1A0NRU from 2026 is the long-awaited masterpiece for enthusiasts of compact GMT watches. With the introduction of this reference, Tudor applies the popular, historically inspired proportions of the Black Bay 58 (39 mm diameter and slim case height) to a full-fledged GMT chronometer for the first time. The visual highlight is the two-tone bezel in deep Black and warm burgundy red with gilt numerals—affectionately dubbed the “Coke” bezel by collectors as soon as it appeared. A watch that combines the unmistakable vintage charm of aviation’s Golden Era with state-of-the-art, Master Chronometer-certified technology.

• Sought-after 39 mm Oyster case in stainless steel: The case offers the perfectly balanced diameter of 39 mm and a significantly slimmer profile than the classic 41 mm GMT models. Satin-finished and polished, it hugs every wrist perfectly with its characteristic drilled lugs.

• Iconic Black/burgundy “Coke” bezel: The bidirectional 24-hour bezel stands out with its two-tone aluminium insert in deep Black (for the night hours) and rich burgundy red (for the daytime hours). The gilt scale accentuates the nostalgic neovintage look.

• Deep Black dial with gilt details: The slightly domed, matte Black dial features gilt lettering and minute-track accents. The characteristic “Snowflake” hands and applied indices are filled with cream-coloured Grade A Swiss Super-LumiNova® for outstanding legibility in the dark.

• Manufacture Calibre MT5452-U (METAS- and COSC-certified): Inside beats the latest-generation in-house GMT automatic calibre. It features an antimagnetic silicon hairspring, is completely resistant to magnetic fields of up to 15,000 gauss, and offers a power reserve of approximately 65 hours with the highest precision (METAS Master Chronometer certified).

• True “Flyer” GMT function: The independently adjustable local-time hour hand can be moved forwards or backwards in one-hour increments while travelling, without stopping the movement or affecting the minutes.

• Scratch-resistant, strongly domed Sapphire Crystal: A highly domed Sapphire Crystal protects the dial and gives the watch the distinctive appearance of the historical acrylic crystals of the 1950s.

• Confident water resistance (200 m / 20 ATM): The screw-down winding crown with a Tudor Rose in relief, together with the solid screw-down case back, guarantees a diving depth of up to 200 metres.

• Riveted-design stainless steel bracelet with “T-fit” clasp: The GMT dream is worn on a three-link stainless steel bracelet with simulated rivet heads along the sides. The patented Tudor “T-fit” rapid-adjustment clasp allows tool-free length adjustment in 5 increments over 8 mm.

• Factory-fresh collector’s highlight (2026 model): As a sought-after model from 2026, reference M7939G1A0NRU combines Tudor’s most coveted history with the highest level of Swiss certification technology. A worldwide bestseller and an absolute must-have for any prestigious collection.
