Tudor Black Bay 58 GMT Jubilee 39mm 7939G1A0NRU

Overview The Tudor Black Bay 58 GMT, reference M7939G1A0NRU-0003, the “Coke” in collector shorthand, is the most technically ambitious watch in the BB58 line. A true flyer GMT in a 39mm case is a meaningful engineering achievement: the local hour hand adjusts in one-hour increments without stopping the movement, a complication Tudor has packaged into the same compact case family as the standard BB58. The 39mm case retains the BB58 GMT’s defining proportions, 12.8mm thick, with a domed sapphire crystal and a gilt-toned dial that references vintage Tudor Submariners of the late 1950s. The black and burgundy bicolour aluminium bezel tracks the second time zone via a 24-hour scale. The five-link, Jubilee-style stainless steel bracelet, new to this reference for 2026, closes with Tudor’s T-fit clasp, adjustable within an 8mm window across five positions without tools. The movement is Calibre MT5450-U: COSC and METAS Master Chronometer certified, anti-magnetic to 15,000 gauss, with a true flyer GMT complication and a 65-hour power reserve. Water resistance is 200 metres. The BB58 GMT occupies a position no other watch in this price range matches directly: GMT function, METAS certification, and a 39mm case at this size, where comparable GMT complications from Rolex sit on larger cases. We see this Jubilee-style configuration as the more versatile of the bracelet options Tudor now offers on this reference, alongside the original rivet bracelet and rubber strap. Brand new, unworn, complete original set with box and papers dated October 2026, at RM18,800, against an RRP of RM22,000.
