75 anniversary of the OMEGA Seamaster: Arrival of Summer Blue


To celebrate OMEGA’s oceangoing icon, the OMEGA Seamaster, the Swiss brand has produced a new collection with bold dials that include a striking tone reminiscent of a perfect day on a boundless sea, the Summer Blue. These timepieces, launched to mark the 75th anniversary of the Seamaster line, pay tribute to an extraordinary history of innovation, exploration, ocean-tested performance and design.

OMEGA Seamaster Summer Blue : 7 Iconic Models

The seven iconic models – eleven watches in all – track a trajectory from dressy to serious dive tech. Common to all is OMEGA’s Summer Blue, used in greater or lesser degrees to reflect the water resistance of the watches. Across the collection, this unique colour gradient ranges from the light top surface, where the Aqua Terra is found aboard yachts and sailing vessels, to the darkest abyss, where the Ultra Deep has made its historic expeditions.

OMEGA’s Summer Blue evokes a pristine ocean on a perfect day. A natural choice of colour for a watch linked to exploration – produced by a brand committed to ocean conservation. The beautiful hue forms the base layer of almost all the dials in the commemorative collection. Layers of varnish, carefully applied or free flowing depending on the required effect, provide the sense of depth.

Aqua Terra : Stylish and Seaworthy

Throughout the years, OMEGA has introduced ocean-inspired design touches, such as sailboat indexes and teak-pattern dials reminiscent of luxury yacht decks. OMEGA’s Aqua Terra collection now includes three new models with symmetrical cases and crowns in stainless steel.

More specifically, the 38 mm edition, powered by OMEGA’s Co-Axial Master Chronometer 8800, has sailboat indexes and a polished and brushed bracelet formed of beautifully rounded links.

The model sized 41 mm offers wearers a choice of a matching bracelet or blue rubber strap. Its driving force is OMEGA’s Co-Axial Master Chronometer 8900. All watches have a new dial in sun-brushed Summer Blue, varnished with a gradient finish to reflect the water resistance of the Aqua Terra: an impressive 150 metres. To complement this colour, OMEGA has filled the rhodium-plated hands and indexes with a unique light blue Super-LumiNova.

Aqua Terra Worldtimer : A dial designed to inspire

Just two years after its launch in 2017, OMEGA adopted laser technology to achieve dials of extraordinary texture and colour. Beautiful visions of Earth viewed from above and wearable on the wrist. With its day-and-night indications and circle of global destinations, the Aqua Terra Worldtimer is the ultimate call to adventure. The very special Seamaster even has its own ocean.

The 43 mm Aqua Terra Worldtimer in stainless steel, available on a matching bracelet or blue rubber strap, presents a colourful view of Earth. Around the dial is a circle of silvery printed global destinations. Bridging the outer and inner displays, hesalite glass reveals a 24-hour reading with light blue to indicate daytime and dark blue to indicate night.

Laser-ablating texture and then colour on a grade 5 titanium plate produced the vision of Earth, which depicts a blue ocean and relief of the continents. Its driving force is OMEGA’s Co-Axial Master Chronometer 8,938. In line with Aqua Terra technology, the Worldtimer is equipped to mark time in a watery world, 150 metres beneath the waves.

OMEGA Seamaster 300 : Oceangoing Professional

Launched in 1957 as part of OMEGA’s “professional” trilogy (along with the Speedmaster and Railmaster), the original Seamaster 300 offered wearers an easy-to-read display and exceptional water resistance, indicated by the “Naiad” star set within the logo on the crown.

The new version continues that legacy with OMEGA’s Co-Axial Master Chronometer calibre 8912, certified at the industry’s highest level by the Swiss Federal Institute of Metrology (METAS). This 41 mm Seamaster 300 has a symmetrical case and crown in polished and brushed stainless steel, with matching bracelet. As the name makes clear, this watch takes 300 metres in its stride and its varnished dial, in Summer Blue, reflects this deeper level of water resistance.

In keeping with the colour code, OMEGA has filled the rhodium-plated hands, recessed hour markers, and open numerals with a unique light blue Super-LumiNova.

This 42 mm Seamaster Diver 300M in stainless steel, available on a matching bracelet or blue rubber strap, is a worthy addition to OMEGA’s classic dive watch collection.

In keeping with its commemorative cousins, it has a Summer Blue wave-pattern ceramic dial, varnished with a gradient finish to reflect its water resistance.

A blue ceramic bezel with new Summer Blue enamel (Grand feu) diving scale encircles the dial, which has rhodium-plated skeleton hands and raised indexes, filled with a unique light blue Super-LumiNova. The Diver’s driving force is OMEGA’s Co-Axial Master Chronometer 8800.

Planet Ocean 600M : Everything the name suggests

The Planet Ocean was released in 2005 with an orange bezel and distinctive helium escape valve, taking its design cues from the Seamaster 300. It also contained OMEGA’s famous Co-Axial escapement, which made its debut appearance in the Calibre 2500. Those looking for serious dive tech seek out OMEGA’s SeamasterPlanet Ocean 600M

As its name makes clear, it is well and truly at home in the ocean, performing brilliantly 600 metres beneath the surface. Powered by OMEGA’s Co-Axial Master Chronometer 8800, this 39.5 mm model has a case and bracelet in stainless steel.

A blue ceramic bezel with light blue diving scale encircles the Summer Blue ceramic dial, which is PVD treated and varnished with a gradient finish, and completed with blued hands and indexes filled with a unique light blue Super-LumiNova.

Ploprof : The world’s most distinctive dive watch

Able to withstand the ocean’s most crushing pressures, the unmistakable Seamaster Professional 600, better known as the “Ploprof” (from PLOngeur PROfessionnel – French for “professional diver”) is one of the most robust and innovative divers’ wristwatches ever made. OMEGA’s ingenious method of fixing the crystal to the tough monobloc case eliminated the need for a helium escape valve. In the Ploprof’s early years, the French oceanographer Jacques Cousteau, and the underwater research company COMEX, relied on the watch during their deep-sea experiments.

This 2023 Ploprof, crafted in O-MEGASTEEL with a sun-brushed Summer Blue dial, takes its design cues from OMEGA’s original model, which arrived on the market in 1971. The bezel ring is a sapphire crystal, to mirror the chemically reinforced monolithic crystal used in those early versions. This transparent crystal, varnished blue on the back, reveals the light blue diving scale beneath.

The iconic monobloc case includes the famous screwed-in crown and the characteristic security pusher at 2 o’clock, which on this edition sports a ring in blue ceramic. A perforated blue rubber strap completes the 70’s look.

Its hard-working calibre is OMEGA’s Co-Axial Master Chronometer 8912.

Ultra Deep : Tribute to OMEGA’s world-record dive

In 2019, the very first Ultra Deep watches made history when they reached the deepest place on Earth. Following that World Record dive to the Mariana Trench, OMEGA transformed the technology into a gamechanging 6,000m collection available to the public. A watch tested in real ocean conditions during its development, water-resistant to 6,000 metres (20,000 ft.), and meeting the ISO 6425:2018 standard for saturation divers’ watches, as certified by the Swiss Federal Institute of Metrology (METAS).

This 45.5 mm model has a case and bracelet in robust O-MEGASTEEL and an extraordinary dial that pays homage to the mysteries of the deep.

Its pattern is an exact representation of the Challenger Deep mapped by the Five Deeps team using almost one million sonar points. Its lacquered finish, produced by letting an ocean of lacquer flow across the dial, has a beautiful sense of depth.

Not revealed is OMEGA’s Co-Axial Master Chronometer 8912, the same calibre powering the legendary Ploprof, that we talked earlier.

The dial even has a playful side. Shining a UV light reveals the words, OMEGA WAS HERE, pointing toward the world record dive of 10,935 m and showing the Western, Central and Eastern Pools.

OMEGA Seamaster : The commemorative caseback

In the 1950s, OMEGA set out to create a symbol that would represent the entire Seamaster collection. It needed to exude the collection’s seafaring heritage, refined style, and robust spirit.

Designer Jean-Pierre Borle found the inspiration on a trip to Venice: the sculpted representations of Neptune’s Seahorse on each side of the city’s iconic gondolas. Every watch detailed has a striking commemorative caseback.
