For over 100 years, Omega have been pushing boundaries, crafting stories and reaching new depths with their exquisite Swiss timepieces. Now, we welcome the new, bright addition into the Seamaster 300M Diver family.
The Omega Seamaster Diver 300M is the longest-running collection from Omega. Speaking directly to the heritage of diving and staple design, these two new distinctive models offer a choice between a brushed mesh bracelet with clasp or an integrated orange rubber strap with fold-over clasp.
In this article, we explore the world of Omega, the heritage of diving watches and the exciting release of two new models.
Dive Watches: Why Omega Dominates the Diving Community
From its introduction in 1948, the Omega Seamaster cemented itself as a pinnacle of underwater reliability and design elegance. Originally conceived as a water-resistence timepiece inspired by waterproof wristwatches made for the British military in World War 2.
The Seamaster took the world by storm by their impressive depth ability, easy visibility and technical ingenuity. When a second Omega Seamaster was launched in 1957, it took place amongst its brother timepieces; the Omega Speedmaster and Omega Railmaster.
Today, the Omega Seamaster Diver 300M is available in over 60 expressions, with interchangeable straps, colourful or sophisticated dials and, of course, the iconic self-winding movement with co-axial escapement.

Why did diving watches become popular?
Diving watches became increasingly popular in the 1950’s and 60’s, where they became less of a necessary piece of life-saving equipment for those working underwater and more of a sophisticated and contemporary accessory for evening attire.
The technical intricacies of these watches enabled them to be precise, reliable and durable. Crafted to succeed in the battle of all elements and uphold their exact movements, the Omega Seamaster Diver 300M held the bar high for those looking for a reliable and ingenious timepiece.
Though today, diving may not be the niche reasoning behind your desire to own an iconic Omega Seamaster Diver 300m, the heritage and story is invoking enough to compel collectors and the every-day watch enthusiast alike. It can also be said their popularity has further grown thanks to their arguably ‘cool’ look and suave connections.
What classifies as a Dive Watch?
In order to accurately define a ‘Dive Watch’, the timepiece must satisfy both technical and practical criteria. At its core, the watch must be water-resistent up to at least 100 metres in order to conform to the ISO 6425 standard.
Some of the other key aspects of the ISO 6425 standard includes:
- A rotating bezel to allow divers to track elapsed dive time, which is crucial for diver’s safety, and a dial that is readable in total darkness.
- Shock resistance to ensure high-durability for impact and stress under any situation, both in and out of water.
- Corrosion resistance is crucial for diving watches for longevity and movement ability.
- Strap and bracelet strength is important for these diving timepieces to feel secure on your wrist.
Combined, these features guarantee that all diving watches meet high-quality standard to keep the wearer safe with the watch's intended use, diving.
Orange Accents and mesh bracelets: The Omega Seamaster Diver 300m

The entire Omega Seamaster Diver 300M collection features refined elements such as oxalic anodised aluminium bezels, domed sapphire crystals, and updated mesh bracelets. These enhancements carry forward the collection’s renowned design DNA while allowing each new model to assert its individuality.
The two new 42 mm models showcase black aluminium dials, rhodium-plated skeleton hands, and white Super-LumiNova for optimal legibility. Vibrant orange accents highlight the central seconds hand, quarter-hour indexes, and the Seamaster name on the dial, creating a dramatic contrast that enhances visibility for divers and underscores Omega’s commitment to both function and form.

Alongside the fresh aesthetic, the collection retains its legendary features: the helium escape valve at 10 o’clock, scalloped bezel, and diving scale with white Super-LumiNova. Each timepiece is powered by the Omega Co-Axial Master Chronometer Calibre 8806 and certified by METAS for exceptional precision, performance, and magnetic resistance.
When is the Best time to Wear Your New Omega Seamaster?
The true beauty of the sophistication of the Omega Seamaster Diver 300m, is the luxurious options of dials, bracelets and straps. The newest models highlight the Omega emblematic orange, but also balances neutral tones of a distinctive stainless steel bracelet. We have reviewed two perfect places to wear your new Omega Seamaster Diver 300m in orange, for the sea and for the shore.
For when You are Diving
For its original intended use, we’ve chosen the Omega Seamaster Diver 300M in Orange with the orange rubber strap. The rubber strap offers complete flexibility and comfort for your diving needs.
Engineered for the depths, the Seamaster Diver 300M delivers robust water resistance up to 300 meters, a helium escape valve for professional saturation diving, and exceptional legibility with Super-LumiNova-coated hands and indexes. Its unidirectional ceramic bezel and precise co-axial movement ensure both safety and reliability underwater.

For When You are Dining
For the more contemporary, and style-conscious wearer, the Omega Seamaster Diver 300M in Orange makes a bold yet refined statement at the dining table.
Pair it with a crisp white shirt or a tailored navy blazer, and the vibrant orange bezel becomes a sophisticated accent rather than a loud declaration. The polished and brushed stainless steel case, laser-engraved ceramic dial, and refined proportions elevate the watch beyond sport utility into the realm of evening elegance.
Whether at a waterfront restaurant or a rooftop soirée, the Omega Seamaster transitions effortlessly from ocean depths to candlelit conversations.
