Omega Seamaster Planet Ocean GMT | Ceramic Deep Black | Ref. 215.92.46.22.01.002

The OMEGA Seamaster Planet Ocean 600M “Deep Black” GMT Ref. 215.92.46.22.01.002 is a bold and technically advanced professional dive watch that combines OMEGA’s renowned underwater performance with the practicality of a second time-zone display. Constructed almost entirely from black ceramic and accented with striking blue details, this 45.5mm Planet Ocean delivers a distinctive, modern presence while maintaining the serious diving credentials for which the Seamaster collection is known.

Black Ceramic Case

The substantial 45.5mm case is crafted from black ceramic, providing excellent resistance to scratches while giving the watch its unmistakable “Deep Black” appearance. Its combination of polished and brushed surfaces adds depth and definition to the monochromatic case design.

A helium escape valve positioned at 10 o’clock reinforces the watch’s professional diving heritage, while the screw-down crown helps provide an impressive 600 meters / 2,000 feet of water resistance.

Black Ceramic Dial with Blue Accents

The black ceramic dial provides a clean yet highly technical appearance. Applied hour markers and broad hands are designed for exceptional legibility, with luminous treatment allowing the time to remain easily readable in low-light and underwater conditions.

Blue accents throughout the dial provide a sharp contrast against the black ceramic construction and coordinate beautifully with the blue details on the bezel and strap.

A date window is positioned at 3 o’clock, while the dedicated GMT hand allows the wearer to simultaneously track a second time zone—making this Planet Ocean equally capable as a travel watch and professional diver.

Ceramic Diving Bezel

Surrounding the dial is a unidirectional rotating black ceramic bezel featuring a diving scale and distinctive blue detailing. The blue section provides a subtle but immediately recognizable contrast to the otherwise stealthy black design.

The combination of ceramic construction and OMEGA’s advanced bezel technology provides excellent durability and resistance to everyday wear.

OMEGA Master Chronometer Calibre 8906

Inside the Deep Black GMT is the OMEGA Co-Axial Master Chronometer Calibre 8906, an automatic movement engineered for exceptional precision, durability and resistance to magnetic fields.

The movement features OMEGA’s Co-Axial escapement, a free-sprung balance with silicon balance spring and a twin-barrel architecture mounted in series. It operates at 25,200 vibrations per hour (3.5 Hz) and provides approximately 60 hours of power reserve.

The Calibre 8906 contains 39 jewels and offers independently adjustable local-hour functionality, making changing time zones particularly convenient without interrupting the watch’s timekeeping.

A transparent sapphire crystal caseback allows the beautifully finished movement to remain visible.

Black Rubber Strap

Completing the Deep Black aesthetic is a black rubber strap with blue stitching and blue accents. The strap complements the ceramic case while providing the comfort, flexibility and water resistance expected from a serious dive watch.

It is secured by a foldover deployant clasp, providing a secure and refined fit on the wrist.
