A BRIEF HISTORY OF THE OMEGA SEAMASTER

The Omega Seamaster is the longest-running collection still being produced by Omega. The very first Seamaster watch was introduced in 1948, and its design was loosely based on watches made for the British Royal Navy towards the end of World War II.

Omega’s diving heritage began in 1932 when they debuted the Marine, the world’s first commercially available dive watch. Tested to withstand sub-aquatic depths, the Marine was worn by Yves Le Prieur, the inventor of the modern scuba mask and tank; and explorer Charles William Beebe, who wore it while riding in a bathysphere. These feats made Omega well-respected for its diver’s watches and paved the way for the introduction of the Omega Seamaster in the following decade.

What made the Seamaster revolutionary for its time was its use of a rubber gasket to secure the movement and provide water resistance. This technology was used in submarines at the time and continues to be used today. So convinced was Omega with its abilities, that in 1956, the Seamaster was attached to an aircraft en route to the North Atlantic. With a water resistance of 60 meters, the original Omega Seamaster was marketed as a water-resistant practical every day watch, closer in design to today’s dress watches.

In the 1950s, the age of exploration gave birth to tool watches made for specific purposes and professions. Omega capitalized on this movement and released their own set of “professional” watches in 1957. Dubbed the 1957 Trilogy, each of the three watches catered to a specific purpose – the Seamaster for diving, the Speedmaster for racing, and the Railmaster for anti-magnetism.

The following year, Omega introduced the Seamaster 300. It was the brand’s first dedicated dive watch, which in a bit of a misnomer, was rated to dive to depths of 200 meters. It eventually gained a reputation as a true tool watch, and accompanied renowned explorer Jacques-Yves Cousteau on his Red Sea expeditions, proving that divers could thrive in gas saturate environments.

The Seamaster 300 went through several iterations in the 1970s, improving its technology further. In 1970, Omega introduced the “PloProf” or Plongeur Professional family, consisting of the Seamaster 600 and Seamaster 1000 -- thereby doubling and tripling the water resistance of Omega watches. These models are the forefather of the PloProf, a cutting-edge watch that was worn by professional divers and used by French diving company COMEX.

In the 1990s, a major marketing move contributed a surge in the Omega Seamaster’s popularity. The Seamaster Diver 300M was featured on the wrist of Pierce Brosnan, when he played 007 in the 1995 film GoldenEye. The Seamaster became the official watch of James Bond, and the ties to the Bond film franchise have continued ever since.

In the 2000s, Omega introduced two new sub-collections – the Omega Aqua Terra, a line of casual-to-sport watches with 150m water resistance; and the Omega Planet Ocean, a line of professional diver’s watches with 600m water resistance.

Omega also demonstrated that its classics can be reinvented. Through the years, they have also introduced clever tweaks and line extensions that revive Seamaster models from the previous decades, such as the Seamaster 300, the PloProf, and the Seamaster 1948.

Today, the Seamaster product range encompasses a broad number of styles, suitable for every situation.


ABOUT THE OMEGA SEAMASTER COLLECTION

The Omega Seamaster collection has a wide array of watches, all suited for active lifestyles. Its models range from splash-proof dress watches, to robust, high-tech professional diver’s watches. Here are the current models under the Omega Seamaster line:

OMEGA SEAMASTER DIVER 300M (1993)

The Omega Seamaster Diver 300M is a professional diving watch. It offers a water resistance rating of 300 meters, and features a helium escape valve on its case, allowing it to be used for saturation diving applications.

Some of the Seamaster Diver 300M’s key features are the scalloped bezel, helium escape valve at 10 o’clock, and skeletonized sword-shaped hands. Many models also feature a wave pattern on the dials. Current production models have switched to ceramic bezels (from aluminum) and ceramic dials with laser-engraved waves.

This collection was made truly famous when Pierce Brosnan wore a quartz Seamaster 300M in the 1995 Bond movie, GoldenEye. His blue Seamaster 300M became the emblematic Seamaster, most recognized for its blue bezel and blue wave dial.

OMEGA SEAMASTER AQUA TERRA (2002)

The Omega Seamaster Aqua Terra is a cross between a dress watch and a sport watch, with a water resistance rating of 150 meters. The key features of the Aqua Terra include smooth round cases, smooth bezels, and teak pattern dials with horizontal or vertical grooves that mimic the wooden decks of luxury yachts.

Aside from the standard time and date models, the Aqua Terra line also has time-only styles, as well as more complicated models like GMTs, annual calendars, day-dates, and world timers.

OMEGA SEAMASTER PLANET OCEAN 600M (2005)

The Omega Seamaster Planet Ocean is a line of professional diver’s watches that are larger than the 300M, and twice as water-resistant with its 600-meter depth rating. It also features a helium escape valve, a unidirectional bezel for measuring diving time, and bright luminous hands and indices for maximum visibility underwater. The Planet Ocean collection offers three-hand editions, chronographs, and models with a GMT function.

OMEGA SEAMASTER HERITAGE EDITIONS

The Omega Seamaster Heritage collection is the brand’s vintage playground. This line features re-editions of vintage Seamaster models with modern enhancements and movements.

OMEGA SEAMASTER 300 – The Seamaster 300 harkens back to the vintage Seamaster introduced in 1957 -- the brand’s first dive watch. It features a rotating timing bezel, a black dial with aged-looking lume, and a 300-meter depth rating.

OMEGA SEAMASTER PLOPROF – The Seamaster Ploprof is the modern reincarnation of the PloProf watches from the 1970s. The name is derived from Plongeur Professionnel, meaning "professional diver" in French. These watches are massive at 55mm, have their crown on the left side, and the crown guards integrated to the case. The current models are water resistant up to 1200 meters, and feature mesh bracelets.

OMEGA SEAMASTER BULLHEAD – The Seamaster Bullhead is a modern take on a 1969 model. As its name suggests, it features a distinctive case reminiscent of a bull’s head. Its winding crown and chronograph pushers are located above the case at 12 o’clock, and it features an additional crown at 6 o’clock to control the internal rotating bezel.

OMEGA RAILMASTER – The Railmaster is part of the three-piece collection introduced in 1957, better known as the “1957 Trilogy”. Especially developed for the scientific community, it has always featured anti-magnetic properties. Today its magnetic resistance is up to 15,000 gauss. What sets it apart from other anti-magnetic models, aside from the high level of anti-magnetism, is that it protects the movement without a using a soft iron cage.

OMEGA SEAMASTER 1948 – The Seamaster 1948 is a faithful reissue of the very first Omega Seamaster model. By today’s standards, its design is closer to a dress watch, with a polished bezel, silvery opaline dial, and a leather strap.

WHAT IS AN OMEGA SEAMASTER?

The Omega Seamaster is a family of watches with water-resistant qualities. It offers a vast range of styles, including splash-proof casual and dress watches, robust professional diver’s watches, and vintage recreations.

HOW CAN I TELL IF MY OMEGA SEAMASTER IS REAL?

Omega is one of the foremost watch brands in the world. They are known for their exquisite watchmaking, with their portfolio composed of functional and complicated watches that don’t sacrifice quality or style. Omega watches are crafted to the highest standards, so any sign of poor quality means it’s likely a fake.

Obvious giveaways are spelling or engraving mistakes, unfinished parts, and features that don’t belong to the specific model that you are looking at.

Before you buy your luxury watch, it is crucial to do research on your chosen model and reference. Familiarity with your chosen watch’s details will help you more easily spot a fake. At SWE, we always tell clients that the best defense against buying a fake timepiece is to get your watch from a reputable and trusted dealer, who can provide a guarantee of authenticity on the watch.

HOW OFTEN SHOULD AN OMEGA SEAMASTER BE SERVICED?

A watch’s service frequency depends on how it is used and stored, and the environment in which it is worn. Water resistance, for example, can be affected by old gaskets or by accidental shocks. Omega recommends that you have the water resistance checked once a year, and have a complete service performed every 5 to 8 years. There can be signs however, that your watch needs maintenance sooner rather than later. Here are Signs It’s Time for Watch Maintenance.
