Description
The Tudor Black Bay 58 GMT 7939G1A0NRU is sourced to order through GrecoWatch in Athens, Greece. This reference combines the Black Bay’s compact proportions with a GMT function for tracking a second time zone.
Its 39 mm stainless steel case has polished and satin finishes. A black dial sits beneath a domed sapphire crystal, paired with a bidirectional 24-hour aluminium bezel. The three-link steel bracelet closes with a Tudor T-fit folding clasp.
The automatic manufacture calibre MT5450-U provides 65 hours of power reserve, with hours, minutes, seconds, date and GMT indications. We seek a 2026 example, new and unworn, as a full set with the original box and papers. GrecoWatch finds this watch on request; ask us to source one for you.
