Omega Seamaster Planet Ocean 600M "Deep Black" GMT 45.5mm Ceramic Diamond/Gems Bezel 215.98.46.22.01.003

The Omega Seamaster Planet Ocean 600M "Deep Black" GMT is among the most audacious watches Omega has ever produced, pushing the iconic Planet Ocean platform to its most luxurious extreme. Introduced as part of Omega's commitment to all-ceramic construction, the Deep Black series replaced conventional steel with black ceramic throughout the case, crown, and pushers, creating a monolithic, virtually indestructible aesthetic that resonated instantly with collectors who wanted a serious dive watch with serious jewellery credentials. Reference 215.98.46.22.01.003 sits at the pinnacle of this lineage, pairing 600-metre water resistance with a gem-set bezel that transforms a professional instrument into a rare and covetable objet.

At 45.5mm, the case commands the wrist with authority. Omega chose ceramic for its extraordinary hardness — ranking just below diamond on the Mohs scale — which means the Deep Black resists the micro-scratches that plague steel and titanium sports watches in daily wear. The unidirectional diving bezel is itself set with diamonds and gems, an extraordinary technical achievement given the challenge of setting stones in a material as hard as ceramic. The result is a bezel that glitters without sacrificing the functional legibility a true diver demands.

The dial doubles down on the drama with a deep black ground punctuated by index and Arabic-numeral hour markers, maintaining high contrast and immediate readability whether worn poolside at a resort or at a black-tie event. The combination of index and Arabic markers gives the dial a rich, layered character that rewards close examination, while the overall layout remains true to the Planet Ocean's professional dive-watch DNA. Luminous treatment on the hands and indices ensures the watch performs in low-light and underwater conditions.

Powering the watch is an automatic movement with GMT complication, allowing the wearer to track a second time zone simultaneously — an invaluable feature for frequent travellers and an appropriate complication for a watch conceived for global adventurers. The movement is housed behind a case rated to 600 metres of water resistance, reflecting Omega's genuine commitment to functional dive performance rather than mere aesthetic posturing. The helium escape valve and screw-down crown further underscore the watch's professional pedigree.

The strap configuration — rubber inner with leather outer — is a thoughtful Omega signature on the Deep Black line, providing the water-safe security of a rubber interface at the case while presenting the refined look of leather against the wrist. It bridges the world of sport and luxury in a single accessory detail that mirrors the watch's dual personality. Changing between water adventures and evening engagements requires nothing more than a swap of the outer leather layer.
