More stylish than ever: Omega updates the Seamaster Planet Ocean
The Planet Ocean represents the pinnacle of Omega’s endeavour in professional dive watches. Introduced in 2005 as an extension of the Seamaster family, it boasted incredibly robust specs from a depth resistance of up to 600m to the incorporation of the helium valve, a pressure safety mechanism for deep-sea diving.
The Planet Ocean constantly pushed the limits of technical and material innovations. For example, it is the first Omega dive watch to be powered by the co-axial escapement movement before it was upgraded to the Co-Axial Master Chronometer. In 2009, it updated the diving scale on the ceramic bezel in Liquidmetal, a groundbreaking, ultra-resistant material.
Reaffirming its deep-sea mastery, Omega created the Planet Ocean Ultra Deep in 2019 for a mission to the deepest point on Earth—the Mariana Trench in the Pacific. That watch was realised as a commercial piece in 2022 with a water resistance of 6,000m. More recently, the Planet Ocean featured its first world time complication.

For 20 years, the Planet Ocean has evolved into a respected sub-category of the Seamaster line. Today, it undergoes another transformation, perhaps its most civilian-friendly version yet, but without compromising its deep-sea performance.
The new Planet Ocean is trimmer than its predecessor by more than 2mm—at 13.79mm in height, it is the slimmest yet. The 42mm case is composed of two parts—the main body and an inner titanium ring—the latter an innovative feature taken from the Ultra Deep that distributes and absorbs external pressure evenly across the case, securing the watch from water seepage.

A new case called for a new bracelet. To match the new dimensions, the integrated bracelet is also slimmer and comprises a series of flat links with two brushed outer rows and one polished row in the centre. It is adjustable to six positions, including an extra diver extension.
The dial is rendered in matte black with the signature arrowhead hands and bold applied indexes. One discernible difference is the Arabic numerals, now openworked and more square.
The caseback is Grade 5 titanium, secured with screws. Here, you will find deep-sea motifs, from the Omega Seahorse emblem to the waved edge.

One key element missing from the current collection is the helium valve. The removal of this once-standard feature was a deliberate decision to streamline the new design. That said, it maintains its remarkable 600m water resistance.
The new collection is available in seven models, including three in signature orange, with a choice of stainless steel bracelets or rubber straps.
The refreshed design will no doubt resonate with those who seek a spirit of adventure tempered by refinement.
