Exactly twenty years after the debut of the first Planet Ocean, Omega returned to the iconic collection with a full-scale reinvention for a new era. The fourth generation introduces an entirely refreshed aesthetic, marked by redesigned case and bracelet architecture, along with technical enhancements that elevate precision, performance, and durability to the highest standards. Yet, the soul of the Planet Ocean remains unmistakable. Its lineage is firmly anchored in the brand’s ocean-faring heritage, preserving the signature elements that have cemented the collection’s legendary status among professional dive watches. This new chapter opens with the launch of seven Co-Axial Master Chronometer models in orange, blue and black.

Omega’s journey in professional dive watches began more than 90 years ago with the groundbreaking Marine, a model that laid the foundation for decades of innovation beneath the surface. The 1950s through the 1970s saw the rise of icons such as the Seamaster 300, Seamaster 1000, and the bold PloProf—each advancing durability and precision at depth. In the 1990s, the Seamaster Diver 300M elevated Omega's reputation even further, merging professional performance with refined aesthetics and becoming one of the brand’s most recognized collections.
When the first Seamaster Planet Ocean appeared in 2005, it paid tribute to the Seamaster 300 of the late 1950s and early 1960s, combining heritage design cues with 21st-century technology. Designed for depths up to 600 meters—twice that of the Seamaster Diver 300M—it quickly became a benchmark in luxury diving timepieces.
The fourth generation refines the Planet Ocean in every dimension. The 42mm cases, now slimmer at just 13.79mm, feature an entirely new two-part construction with an internal Grade 5 titanium ring to ensure water resistance to 600 meters. The helium escape valve, long a hallmark of the series, has been retired in favor of a purer, more architectural form defined by sharp edges and modern geometry.
Reworked bracelets integrate seamlessly into the case, offering improved ergonomics and six-position adjustment, while new rubber strap options continue the sporty heritage of the Seamaster family. Each model features a matte black dial with applied indexes and signature arrow hands filled with Super-LumiNova, paired with newly designed open, angular numerals—a contemporary nod to the 2005 original.
The titanium screw-down case back bears the engraved hippocampus emblem, surrounded by wave detailing and depth indications, reinforcing both the strength and the artistry of Omega’s craftsmanship.
True to its lineage, the color orange remains an integral part of the collection. Achieving this vivid shade in ceramic required years of material research and refinement. The result is a striking new orange ceramic bezel with a white hybrid ceramic diving scale—featured on three of the seven launch models, alongside blue and black variations. All models are powered by the Co-Axial Master Chronometer Caliber8912, offering a 60-hour power reserve and the precision, anti-magnetism, and durability certified by METAS.
