Description
Tudor Black Bay 54 79000N is sourced to order through GrecoWatch in Athens, Greece. This compact diving watch has a time-only display and 200m water resistance.
The 37 mm stainless steel case houses a black dial beneath a domed sapphire crystal. A unidirectional bezel with an aluminium insert measures elapsed time, while the stainless steel three-link bracelet closes with a Tudor T-fit folding clasp.
The automatic MT5400 calibre provides approximately 70 hours of power reserve and displays hours, minutes and seconds. GrecoWatch seeks a 2026 example, new and unworn, as a full set with the original box and papers and Tudor’s 5-year international warranty. GrecoWatch does not hold this watch; contact us to source one on request.
