Omega Seamaster 300 Summer Blue 234.30.41.21.03.002 41 mm Steel Blue Dial Watch for Men

Part of OMEGA's Summer Blue series, this Seamaster 300 has a symmetrical 41 mm steel case, polished and brushed, with a bracelet to match. Its varnished dial fades in a gradient of Summer Blue, and light blue Super-LumiNova fills the rhodium-plated hands, the recessed hour markers and the open numerals.

The caseback is stamped with a commemorative Seamaster logo, a trident-bearing Poseidon with two seahorses, uniting OMEGA's 1956 original and today's design. Inside is the Co-Axial Master Chronometer calibre 8912, METAS-certified, resistant to 15,000 gauss and fitted with two barrels in series for 60 hours of reserve, plus a time zone function. Water resistance reaches 300 metres; the foldover clasp has a comfort setting.
