Overview of the Seamaster Planet Ocean
Omega opens its volley with equal measures of class and mass; the 45.5mm stainless steel case features a full-bodied presence that surpasses the comparatively dainty Submariner’s 40mm span. This watch totals 57.6mm across the wrist and is 19.4mm thick, making it a heavy, gigantic luxury watch ideal for larger wrists or enthusiasts with Hublot-era standards and boasts a caliber 9300 within its extra-large casing.
As for the bracelet and clasp, its stainless steel construction and oval cross-section 3-link bracelet add weight and a sense of quality that smaller watches sometimes lack. The clasp offers the kind of security that no friction-fit competitor can match. Even better, the clasp it offers one of the best deployment dive extensions in the business; it’s equally useful over a dive suit or a winter coat.
All in all, the Omega Seamaster Planet Ocean Chronograph is the perfect go-to when the mantra is “go-big or go home.”
An expressive, full-sized watch, the Planet Ocean 600M is a sophisticated companion that offers its owner the advantages of Swatch Group’s formidable materials science labs.
The unidirectional diving bezel featured on this dive watch is a type of ceramic that ranks with sapphire crystals on the Mohs Hardness Scale. Nothing short of a diamond can damage the bezel, which is far removed from the “weathered bezel” look that marks nearly every vintage dive watch in the past.
The Omega Seamaster Planet Ocean Collection Timeline
Browse the lifespan of this collection, categorized by release date and features.
2005/6: Omega introduced the Planet Ocean as a luxury watch in their Seamaster line. This first generation was positioned as a tool watch that looked good enough for casual wear and had caliber 2500 and 3313 options.
2009: They introduced their latest innovation, with a limited edition ref. 222.30.42.20.01.001 that featured LiquidMetal, a protective alloy designed to strengthen the material and prevent discoloration.
2011: The Planet Ocean received an aesthetic upgrade as well as a new movement: the Caliber 8500. The result was an extended power reserve, skeleton and smaller case options, more colors, and more material options.
2013: Omega added the GMT feature with an adjustable hand, 24-hour bezel, and a new size of 43.5mm.
2016: This marked the third generation in the Omega Planet Ocean with the integration of galvanized rubber and LiquidMetal on the bezel, like with this ref. 215.92.46.22.01.003. They also introduced the Caliber 8900, Omega’s first master chronometer movement.
2022: In March Omega released the Seamaster Planet Ocean Ultra Deep to the public. In testing it reached a depth of 6269m in the Mariana Trench—the equivalent of the Burj Khalifa stacked seven and a half times.
For enthusiasts of the brand, it wasn’t a surprise to see James Bond sporting an Omega Seamaster in 1995’s Goldeneye, or that Omega replaced Rolex’s Submariner as 007’s watch of choice since then.

Watch Features
Inside its burly ferrous carapace, the Omega Seamaster Planet Ocean 600M benefits from numerous advancements that make this watch an ideal choice for professional and casual divers alike.

Here are some other notable features of the Omega Seamaster:
> Automatic

Additionally, a A standard helium release valve keeps a lid on the works when accumulated nitrogen of exotic gas environments asserts itself during post deep-dive ascents. Another particularly useful feature for divers is the ability to set two timers using the chronograph and bezel, making it ideal for dives as well as ease of use. When combined with the audibility of the bezel as it moves and the luminescence of the timepiece, this tool watch is ideal for underwater exploration.
