Omega Seamaster Planet Ocean 600M GMT "Oreo" 215.30.44.22.01.001

It was with OMEGA’s maritime legacy in mind that the brand launched its Planet Ocean line in 2005. The stylish OMEGA Seamaster Planet Ocean 600M Master Chronometer GMT pays homage to OMEGA’s dive watch heritage.

This model, with its scratch-resistant sapphire crystal, features a black ceramic dial with Arabic numerals, a date window at the 3 o’clock position and a central GMT hand. Mounted on the 43.5 mm stainless steel case is the world's first polished bi-ceramic black and white bezel. Here, the numerals and scaling are delivered in contrasting colours to separate night from day.

Other features include an alveol screw-in caseback and a stainless steel bracelet with patented extendable foldover clasp.

The OMEGA Seamaster Planet Ocean 600M Master Chronometer GMT is water resistant to 60 bar (600 metres / 2000 feet), and has a helium-escape valve. The OMEGA Master Chronometer calibre 8906 at the heart of this timepiece can be seen through the transparent caseback. To achieve Master Chronometer status, it has passed the 8 rigorous tests set by METAS (The Swiss Federal Institute of Metrology).

Founded in 1848 by Louis Brandt in Switzerland, Omega has grown into one of the most respected and innovative names in watchmaking. The brand’s early focus on precision earned it accolades at international observatories and competitions, setting the stage for decades of horological achievement. Omega became the official timekeeper for the Olympic Games in 1932, and in 1969, the Speedmaster Professional—nicknamed the "Moonwatch"—made history as the first watch worn on the lunar surface during NASA’s Apollo 11 mission. Omega’s innovations continued with the introduction of the Co-Axial escapement in the late 1990s, a groundbreaking movement that dramatically reduced friction and improved long-term accuracy.

Omega’s lineup showcases a wide range of iconic models that reflect the brand’s legacy and versatility. The Seamaster, introduced in 1948, is a favorite among divers and famously worn by James Bond since 1995’s GoldenEye, blending technical capability with cinematic cool. The Speedmaster remains one of the most storied chronographs in existence, while the Constellation is known for its refined design and chronometric precision. The De Ville collection offers a more elegant, dress-focused aesthetic, often featuring high-end complications and meticulous finishing. Omega continues to lead with innovations like Master Chronometer certification, METAS testing, and antimagnetic technology—ensuring that its watches are not just beautiful, but built for the demands of modern life.
