OMEGA Seamaster 300

Omega's Seamaster 300 in reference 234.93.41.21.99.002 comes in a platinum case measuring 41 mm across, 14.65 mm thick, with a lug-to-lug of 48 mm. This is a dive watch with a unidirectional rotating bezel and a screw-down crown, and the blue dial sits under a domed sapphire crystal with anti-reflective treatment. The self-winding calibre 8913 drives the watch, certified as a Master Chronometer by METAS and resistant to magnetic fields up to 15,000 gauss. It carries a freesprung balance with silicon spring and two barrels mounted in series, giving 60 hours of power reserve. A display back shows the finishing, including the 18K Sedna gold rotor. The blue alligator leather strap closes with a platinum foldover clasp. Omega rates the case to 300 metres.
