The Omega Seamaster Planet Ocean ‘Deep Black’ was introduced in June 2016. It is the first of Omega’s Planet Ocean watches to feature a case almost entirely crafted from high-tech ceramics, including its unidirectional bezel and caseback – the latter fitted with a new patented ‘Naiad’ lock to have its engravings properly lined up at all times.The 215.92.46.51.01.001 is a 2017 addition. Instead of the GMT caliber 8906, it is now powered by the caliber 9900 Master Chronometer Chronograph movement.
