Omega Seamaster Planet Ocean 600M 215.30.44.21.03.001 43.5 mm Steel Blue Dial Watch for Men

Blue ceramic is used for both the dial and unidirectional bezel of reference 215.30.44.21.03.001, a 43.5 mm Seamaster Planet Ocean 600M in stainless steel. The bezel's diving scale is OMEGA Liquidmetal™, and the dial combines Arabic numerals with a 3 o'clock date window.

Around the back, the alveol screw-in caseback reveals calibre 8900, whose Master Chronometer status required passing eight tests set by METAS; it resists 15,000 gauss, adds a time-zone function and holds 60 hours of reserve from two barrels in series. A helium escape valve is fitted, water resistance reaches 600 metres, and the steel bracelet uses a patented extendable foldover clasp.
