Tudor already had a GMT in the lineup with the 41mm Black Bay GMT launched in 2018, but at 14.6mm thick it wore like a hockey puck. The Black Bay 58 GMT marries the compact, universally wearable 39mm case of the BB58 with a proper integrated GMT complication, showcasing one of the industry's most impressive movements. The Manufacture Caliber MT5450-U, produced by Kenissi—Tudor's movement-making joint venture with Chanel—is built on architecture that's become the backbone of the modern Black Bay family. With integrated GMT architecture, the dual-time zone function allows for a jumping local-time hour hand that can be set independently and features a 24-hour GMT hand plus an instantaneous date, making it the preferred \"flyer\" GMT configuration that collectors cherish. \u003cbr\u003e\u003cbr\u003eThe watch boasts a non-magnetic silicon balance spring, free-sprung variable-inertia balance, and traversing bridge with two-point anchoring, regulating at 28,800 vph with a 65-hour power reserve. Impressively, it carries both COSC chronometer and METAS Master Chronometer certifications—tested to 0\/+5 seconds per day and anti-magnetic to 15,000 gauss. Tudor under-promises with -2\/+4 seconds on their watches; METAS holds them to an even tighter five-second window.\u003cbr\u003e\u003cbr\u003eWhat sets this particular reference apart is its bezel. The \"Coke\" colorway features black and burgundy on a bidirectional 24-hour rotating ring made of anodized aluminum with gilt markings, evoking vintage Rolex GMT-Masters. The domed matte black dial showcases gilt applied indices and matching gilt snowflake hands, providing warmth with SuperLuminova fills. This aesthetically pleasing watch looks aged, even straight out of the box. At 39mm wide, 47.8mm lug-to-lug, and only 12.8mm thick, it offers a more wearable option than previous Tudor GMT models—improving on thickness significantly. The redesigned screw-down crown blends seamlessly with the case, while the three-link riveted steel bracelet with T-fit quick-adjust clasp rounds out this travel-friendly package. Truly, the Tudor Black Bay GMT Coke watch is the compact GMT that fans desired from Tudor, in the colorway that everyone wanted from Rolex.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eKEY DETAILS\u003c\/strong\u003e\u003cbr\u003eName: Tudor Black Bay 58 GMT \"Coke\"\u003cbr\u003eReference: 7939G1A0NRU\u003cbr\u003eCase Material: Stainless Steel (polished and satin-brushed)\u003cbr\u003eCase Diameter: 39mm\u003cbr\u003eCase Thickness: 12.8mm\u003cbr\u003eLug-to-Lug: 47.8mm\u003cbr\u003eLug Width: 20mm\u003cbr\u003eBezel: Bidirectional 24-hour rotating, stainless steel with black and burgundy anodized aluminum insert, gilt markings\u003cbr\u003eCrystal: Domed sapphire\u003cbr\u003eCaseback: Solid steel, screw-down\u003cbr\u003eDial: Black, domed, matte with radial brush, gilt applied hour markers, date window at 3 o'clock\u003cbr\u003eHands: Snowflake (gilt, hours and GMT), lollipop seconds hand\u003cbr\u003eLume: SuperLuminova (hands and indices, warm tone)\u003cbr\u003eMovement: Tudor Manufacture Caliber MT5450-U\u003cbr\u003eJewels: 34\u003cbr\u003eFrequency: 28,800 vph (4 Hz)\u003cbr\u003ePower Reserve: Approx. 65 hours\u003cbr\u003ePrecision: COSC Chronometer + METAS Master Chronometer certified (0\/+5 sec\/day per METAS) \u003cbr\u003eMagnetic Resistance: Up to 15,000 gauss\u003cbr\u003eFunctions: Hours, minutes, seconds, GMT 24-hour hand, instantaneous date\u003cbr\u003eWater Resistance: 200 meters \/ 660 feet\u003cbr\u003eBracelet: Oyster with Tudor T-fit quick-adjust clasp\u003cbr\u003eCrown: Stainless steel, screw-down, flush-mounted design\u003cbr\u003eSpecial Features: Integrated \"flyer\" GMT complication, silicon non-magnetic balance spring, free-sprung variable-inertia balance, tungsten monobloc openworked bi-directional rotor.\u003c\/p\u003e","brand":"Tudor","offers":[{"title":"Default Title","offer_id":45213707993167,"sku":"5978C","price":4945.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0636\/1733\/5375\/files\/237a9b6fd9fdb0a93824756e8ab4b24b.jpg?v=1778539498","url":"https:\/\/kingdomwatchcompany.com\/es\/products\/tudor-black-bay-gmt-coke-watch","provider":"Kingdom Watch Company","version":"1.0","type":"link"}
