Omega Seamaster Planet Ocean 600M Co-Axial Master Chronometer GMT 45.5mm White Ceramic Diamond and Sapphire Bezel White Mother-of-Pearl Dial Leather and Rubber Strap 215.98.46.22.05.001 - BRAND NEW

The Omega Seamaster Planet Ocean 600M is one of the most respected professional dive watch lines in the world, tracing its roots to Omega's long heritage of deep-sea exploration and its partnership with the world's leading diving and marine institutions. Since its introduction, the Planet Ocean has been distinguished from other Seamaster variants by its larger, more robust case architecture, heightened water resistance rating, and uncompromising commitment to in-house movement technology. Reference 215.98.46.22.05.001 represents that lineage taken to its most glamorous extreme, fusing proven tool-watch engineering with extraordinary gem-set luxury.

The 45.5mm case of this reference is crafted entirely in white ceramic — a material prized in high-end watchmaking for its exceptional scratch resistance, its cool and smooth feel on the wrist, and the brilliance of its surface finish, which retains its polished appearance far longer than precious metals. White ceramic at this scale is technically demanding to produce, requiring precision sintering and machining, and Omega's expertise in ceramic case construction is well established across the Seamaster and Speedmaster lines. The result is a case that feels as refined as it is durable.

The bezel is the most visually arresting element of this reference: it is set with a constellation of diamonds and sapphires, transforming what is functionally a rotating dive bezel into a jewel that commands attention. Beneath it, the dial presents a white mother-of-pearl surface — a material harvested from mollusks and prized for its organic iridescence, which shifts and shimmers as light strikes it from different angles. Hour indices and Arabic numerals complete the dial layout, ensuring legibility is never sacrificed for beauty, a balance that defines the finest dress-sport watches.

Powering reference 215.98.46.22.05.001 is an Omega Co-Axial Master Chronometer movement with GMT complication, representing the brand's highest level of in-house certification. Master Chronometer designation means the caliber has been tested and certified by METAS, the Swiss Federal Institute of Metrology, to meet stringent standards of precision, antimagnetic performance, and reliability — standards that exceed the traditional COSC chronometer benchmark. The GMT function adds a second time-zone hand, making this watch a practical companion for international travelers as well as a collectible object.

The wrist presence of this watch is deliberate and theatrical. At 45.5mm in white ceramic with a gem-set bezel and iridescent mother-of-pearl dial, it is conceived for those who want a statement piece that does not compromise on horological substance. The dual-layer strap — rubber inner construction bonded with alligator leather outer — speaks to the same philosophy: the comfort and water-resistance practicality of rubber combined with the luxurious tactile quality of genuine leather. It sits beautifully on the wrist and complements formal or resort attire with equal confidence.
