After the success of the Planet Ocean 'Deep Black' in 2016, OMEGA wanted to take its ceramic watches one step further. The OMEGA Seamaster Planet Ocean Big Blue is a dive watch with the GMT function integrated into a single blue ceramic block.
The 45.5 mm case of this automatic watch features a blue dial with an orange GMT minute track. The 18K white gold hands and hour markers coated with white Super‑LumiNova add a luminous touch, while the blue ceramic bezel features a diving scale with Liquidmetal™ numerals. A mixture of orange rubber and ceramic covers the first 15 minutes of the bezel to support its diving function.
The back of this OMEGA Seamaster features a screw‑in caseback with a wave pattern and a unique OMEGA innovation: a patented ceramic "Naiad Lock" which allows the engraving to remain in the same position at all times. Presented on a blue rubber strap, the "Big Blue" offers a sports watch style that is powered by the OMEGA Master Chronometer calibre 8906. It is water‑resistant to 60 bar and can withstand magnetic fields of up to 15,000 gauss.
