In the world of professional divers, few collections are repositories of luster and history as much as the Seamaster collection. With the fourth generation, unveiled in 2025, the Biel-based Maison opens a chapter that stands in continuity with its technical history – but at the same time propels it into more rigorous, more essential, and surprisingly more modern design territory.
Timeline of the Seamaster line, Planet Ocean.
Seven new models, three dial types, a total case redesign, and a renewed approach to ergonomics and materials. Let’s dive in!
A pioneering journey nearly a century long
The genealogy of the Planet Ocean cannot be understood without looking at Omega’s entire diving tradition. It all begins in

Over this span of decades, Omega refined waterproofing techniques, solutions for shock resistance and pressure resistance, and progressively introduced advanced materials. This heritage enables, in 2005, the birth of the collection destined to become a pillar of modern diving watchmaking: the Planet Ocean.
2005-2014: the first and second generations, between depth and innovation
The 2005 Planet Ocean was born with a clear mission: to exceed established professional standards. With water resistance to 600 meters – twice that of the Diver 300M – it sets an immediate technical benchmark. The design deliberately recaptures the styling cues of the Seamaster 300 from the 1950s and 1960s: highly legible black dial, Arabic numerals at the quarter hours, arrow hands, and the dive scale of the diving bezel.
In 2009 came the first technological breakthrough: Omega introduced Liquidmetal™ for the first time in a Swiss watch, used for the scale of the black ceramic bezel. The ceramic-metallic glass union brings hardness, aesthetic uniformity, and scratch resistance beyond previous levels, opening a new era of construction.

The second generation of 2011 implements substantial innovations: all-ceramic bezels, polished dials, sapphire crystal casebacks, and most importantly, the upgraded 8500 caliber with Si14 silicon balance spring, which increases magnetic resistance and introduces a higher standard of precision.
In 2014, Omega solves one of the most complex challenges in materials chemistry: achieving a stable, intense and durable orange ceramic. The platinum Planet Ocean GMT bears the inscription “World Premiere,” testifying to a technical achievement never before achieved.
2016-2022: the third generation and the arrival of Ultra Deep
2016 marks the entry of METAS-certified Co-Axial Master Chronometer movements: precision, antimagnetism and stability become foundational elements. The cases become thinner, 18K Sedna™ gold enters the scene, the bezel integrates rubber inserts, and the Deep Black series is born, entirely in ceramic, designed to withstand up to 600 m.
In 2019, the Ultra Deep descends to the deepest point on Earth. The production model, introduced in 2022, maintains endurance to 6,000 meters according to ISO 6425 standards for saturation diving, employing advanced materials such as O-MEGASTEEL, a high-performance alloy with whiter color and superior corrosion resistance.
This engineering experience will be instrumental for the fourth generation.

2025: the fourth generation
Omega rethinks the entire construction ecosystem of the Planet Ocean. While retaining the original size (of the 2005 Planet Ocean and 1960s Seamaster 300) of 42 mm, the watch is radically redesigned: reduced thickness from 16.1 mm to 13.79 mm, flattened profile thanks to a front sapphire crystal, and a slimmer bezel.
But the most significant technical breakthrough is hidden in one detail. Each model incorporates an
A new case architecture
The silhouette now features sharper lines and more pronounced angles, inspired by Omega models of the 1980s and 1990s. The steel case complements a new bracelet with flat links (two brushed outer rows and a polished middle one), which is thinner, more ergonomic, adjustable to six positions, and equipped with the diver’s extension. The collection also includes rubber straps with a folding clasp.
The screw-down caseback is made of grade 5 titanium: it reduces weight, increases strength, and introduces a wavy profile that echoes the stylistic heritage of the Seamaster. At the center is Omega’s undisputed and timeless hippocampus.
Dial and bezel
The dial is now matte black on all models-a functional choice that prioritizes legibility. Arrow hands and applied hour markers remain consistent with the collection’s DNA, filled with Super-LumiNova.
The typography of the Arabic numerals, however, evolves: perforated, squared off, more technical. A return to the origins of 2005, but with a contemporary twist.
Variants include:
– Orange models: with matte orange painted Arabic numerals, orange ceramic [ZrO2] bezel with white ceramic hybrid scale.
– Blue models: with matte white painted Arabic numerals, blue [ZrO2] ceramic bezel with white enamel scale.
– Black models: with rhodium-plated Arabic numerals, black [ZrO2] ceramic bezel with white enamel scale.
On each dial, the Omega logo is rhodium-plated while the transferred lettering is always white.
The movement: Co-Axial Master Chronometer 8912
All watches are powered by Omega’s Co-Axial Master Chronometer caliber 8912-already used in the Ultra Deep models. These automatic movements offer a 60-hour power reserve and meet the highest standards of precision, performance and magnetic resistance, certified by the Swiss Federal Institute of Metrology(METAS).
A movement designed for extreme operating conditions, now housed in a slimmer, ergonomically advanced case.
The Planet Ocean 2025 campaign
With the global campaign spearheaded by Glen Powell and Aaron Taylor-Johnson, OMEGA is reiterating a message that runs through two decades of Planet Ocean: dive watchmaking is a terrain of exploration, and those who choose these instruments are not simply looking for a timepiece, but a reliable companion, prepared and built for the seabed as much as for everyday life.

Conclusions and prices
The fourth generation of the Planet Ocean does not propose a simple aesthetic or functional update. It is the result of a research process that integrates into the new timepiece: the innovations pioneered in the Ultra Deep, the formal rigor of the historic Seamaster models, the design maturity gained over twenty years, and a new focus on materials and ergonomics.
The watch retains its soul – sturdy, professional, deeply connected to the diving world – but takes on more contemporary, more controlled proportions, lines and technical solutions, more consistent with the watchmaking vision of the years to come.
The price lists for each version are respectively:
- $9,200.00 black with bracelet
- €9,200.00 blue with bracelet
- $9,400.00 orange with bracelet
- $8,500.00 black with black strap
