Planet Ocean 600m Co‑axial Chronograph Master Chronometer 45.5mm

In 2005, OMEGA launched its Planet Ocean line, with its maritime heritage in mind. Today, the elegant OMEGA Seamaster Planet Ocean 600M Master Chronometer pays tribute to OMEGA’s dive watch heritage.

This model features a scratch-resistant sapphire crystal and a black ceramic dial with Arabic numerals and a date window at 6 o'clock. The dial features a small seconds hand and 60-minute and 12-hour counters for an intuitive reading of elapsed time. The bezel, which combines black ceramic and orange rubber for the first time, is mounted on a 45.5 mm stainless steel case and features a Liquidmetal™ diving scale.

The watch also stands out with its screwed-down caseback with a honeycomb design and its stainless steel bracelet closed by a patented extendable folding clasp.

The OMEGA Seamaster Planet Ocean 600M Master Chronometer Chronograph is water resistant to 600 metres (60 bar / 2,000 feet) and is equipped with a helium-escape valve. The OMEGA Master Chronometer calibre 9900 at the heart of this timepiece is visible through the transparent caseback. To achieve Master Chronometer certification, it had to pass eight rigorous tests set by METAS, the Swiss Federal Institute of Metrology.
