About this reference
The Seamaster 300 that carries a GMT is 234.30.41.21.01.001, and Omega has built it since 2021. Steel, 41 mm across and 13.85 mm thick, with a black dial, applied markers, a unidirectional bezel and a steel bracelet with a folding clasp. Master Chronometer calibre 8912 is automatic and anti-magnetic, visible through the caseback; the crown screws down and the watch is rated to 300 metres. The time-zone function is what separates it from a straight three-hand heritage diver.
Fifteen listings reach Saudi Arabia under this code. 234.30.41.21.03.001 and 234.30.41.21.03.002 keep the 234.30.41.21.03 pattern and are the first endings to rule out. 233.20.41.21.01.001 and the 235.10.38.20.13.001 and 235.10.38.20.06.001 codes are different Seamaster 300 references. If the offer does not show the GMT, it is not this watch.
