The Omega Seamaster 300 Ref. 234.30.41.21.03.002 is a contemporary reissue of a 1957 dive watch icon — upgraded with modern Master Chronometer technology and refined vintage styling. With a rich blue dial and bezel, this model offers a slightly dressier take on the classic Seamaster tool-watch aesthetic.
The sandwich-style dial features recessed vintage-tone Super-LumiNova markers, broad arrow hands, and a minimalist, no-date layout. Framed by a blue aluminium bezel with a retro-style diving scale, the watch balances clarity with heritage charm. At 41mm, the brushed steel case wears confidently with signature twisted lugs and polished accents.
Inside is the OMEGA Calibre 8912, a Master Chronometer-certified movement with twin barrels, a free-sprung balance, anti-magnetic construction, and a 60-hour power reserve — all visible through the sapphire caseback.
