The OMEGA Seamaster Planet Ocean 600M 43.5mm (Ref. 215.30.44.21.01.002) features the world’s first black ceramic bezel with orange rubber combination and Liquidmetal diving scale, creating a distinctive two-material bezel construction that provides superior scratch resistance alongside high-visibility timing markings. The polished black ceramic dial with Arabic numerals and alveol screw-in caseback contribute to a specification built around 600m saturation diving capability, validated through all eight rigorous METAS tests covering precision, magnetic field resistance, waterproofness, and power reserve.

At 43.5mm with 16.09mm thickness through stainless steel construction, this provides commanding professional diving presence whilst the orange rubber bezel elements create striking visual contrast against the black ceramic and steel. The date window at 3 o’clock and Arabic numeral dial layout maintain clear time reading essential for professional diving operations whilst the helium escape valve confirms saturation diving credentials.

The Master Chronometer Calibre 8900 delivers 60-hour power reserve with 15,000 gauss magnetic resistance through METAS certification whilst the free-sprung balance with silicon balance spring and two barrels mounted in series provide consistent power delivery. The time zone function adds international travel utility alongside the primary diving specification whilst the rhodium-plated rotor and bridges with Geneva waves in arabesque are visible through the transparent caseback.

The stainless steel bracelet with patented extendable foldover clasp and diver extension accommodates wetsuit wear whilst the domed sapphire crystal with anti-reflective treatment ensures optimal underwater visibility. The screw-in crown and 600m water resistance complete a professional instrument specification that positions this firmly at the serious end of the Planet Ocean range.
