Tudor Black Bay 58 GMT Bracelet 39mm 7939G1A0NRU

Overview Tudor's Black Bay GMT had run at 41mm since 2018. The 7939G1A0NRU moved that function into the 39mm Black Bay 58 case in 2024, a new addition for buyers who wanted the complication but found the larger format too much wrist for daily use. The 39mm case changes nothing about how the GMT works. It changes who the watch fits. The case is 39mm stainless steel, 12.8mm thick, with the BB58's domed bezel and short lug geometry, on the three-link rivet-style stainless bracelet with Tudor's T-fit clasp. The bezel insert is black and burgundy, Tudor's own name for the colourway; it's the one enthusiasts commonly call "Coke," after the visual similarity to a red-and-black GMT bezel, though the red here runs darker burgundy rather than the brighter tone the nickname implies. The dial is black with gilt applied hour markers, and Tudor's snowflake hand set carries the same gilt finish across the hour and GMT hands, with a lollipop seconds hand borrowed from the Black Bay 54. The movement is the Calibre MT5450-U, Tudor's in-house automatic with an integrated GMT function, COSC and METAS Master Chronometer certified. Power reserve is 65 hours, a step below the 70 hours common elsewhere in Tudor's current lineup, the trade-off for fitting the GMT module into the smaller case. The local hour hand adjusts independently in one-hour increments without stopping the seconds hand. Against the standard Black Bay 58, M79030N in black, M79030B in blue, the 7939G1A0NRU adds a genuine GMT complication at a modest premium. Against the 41mm Black Bay GMT (M79830RB-0001), the case size is the deciding variable: the same independently-adjustable GMT function, a meaningfully different wearing experience. We believe RM17,000 is a rational secondary entry for this reference; it's a recent introduction with no speculative premium attached, and the pricing reflects the watch rather than its novelty. This piece is brand new, unworn condition, complete original set with box and papers dated August 2026, at RM17,000 against an RRP of RM21,530.
