OMEGA Seamaster Planet Ocean vs Seamaster 300m

Omega News & Releases

OMEGA has been manufacturing world-class watches since their inception in 1848. The Swiss luxury brand is known for its superior quality and precision, which have allowed OMEGA to be the official timekeepers of the Olympic Games since 1932 and to produce the first watch taken to the moon in 1969.

Some of the most popular OMEGA watches include the OMEGA Seamaster Planet Ocean and the OMEGA Seamaster 300m, which you can find here at Banks Lyon. As official OMEGA stockists, we offer a wide range of Seamaster models designed to match your lifestyle, whether you’re in a tuxedo or a diver’s suit.

OMEGA Seamaster Collection

OMEGA Seamaster watches date back to 1948, when the Swiss brand unveiled the line to commemorate its 100th anniversary. Up until the 1960s, the timepieces had few functions other than time and date display and were commonly worn as a dress watch; today, the Seamaster is associated with sports and its models are often used as sports watches.

The collection became sportier during the 1970s, when OMEGA started to include diver-oriented features such as higher water resistance, calibrated rotating bezels, high-visibility dials and chronograph functions. Offering innovative design, top-of-the-range precision, world-class technology and comfort for all wearers, professional or otherwise, the range is perfect for divers and watch aficionados everywhere.

The Seamaster is popular among celebrities and royalty alike, with famous wearers including Prince William, Joe Biden and Jeremy Clarkson. The models are also associated with James Bond, as the well-known English spy has been wearing them on-screen since 1995.

The automatic watches in the Seamaster line are C.O.S.C.-certified. This means that the movements in each timepiece are incredibly precise, having had to pass rigorous tests. Also, the diver’s bracelet is a key feature that provides all wearers with peace of mind; the sturdy nature of the bracelet means you don’t have to fear them unclasping in the middle of a dive or even during a special evening out.

The helium escape valve is another great feature of the range. It improves the performance of the watch, especially important for professional divers working at depth for long periods of time. This means that gases like helium and hydrogen can enter the watch or build up under pressure – depending on the quality of the watch, this can actually damage it, such as making the crystal detach from the piece.

However, with a helium escape valve, all trapped gases are released when the differential between the inner and outer pressure reaches a certain level, ensuring the functionality and, of course, the physical condition of the watch.

Two of the collection’s most famous lines are the OMEGA Planet Ocean watches and the Seamaster 300m, both of which present several similarities and differences. These make them suitable for everyday wear, sports events and special occasions, depending on your preferences.

The collection showcases the Swiss watchmaker’s passion for adventure and its strong maritime heritage.

OMEGA Seamaster Planet Ocean Watches

Inspired by the ocean, the pieces in the OMEGA Seamaster Planet Ocean collection are the epitome of classic appeal, contemporary functionality and superb craftsmanship. Preferred by professional divers around the world, this line pays homage to OMEGA’S ocean heritage and is known for pushing the boundaries of watchmaking.

The collection has been selected by the British Royal Navy and helped two divers break world records in 1968 for simulated diving at 635m, and it was also chosen by Jacques Yves Cousteau for his diving endurance experiments. The OMEGA Seamaster Planet Ocean is characterised by a helium release valve and a chronometer certification, as well as strong water resistance of up to 600m (or 2,000ft). Due to these and other excellent features, the timepieces are considered one of the best diver watches of all time.

This is also the first time that rubber has been blended with ceramic to create a new unidirectional diving bezel; orange rubber covers the first 15 minutes while Liquidmetal® is used for the markings.

Innovation and performance are perfectly balanced in this watch, and its gorgeous design also makes it ideal as a statement piece. The OMEGA Seamaster Planet Ocean 600m Master Chronometer is available for purchase at Banks Lyon for £5,280 at 0% finance.

Planet Ocean or Seamaster 300m?

Some of the differences between the models in these collections include their water resistance, as mentioned above. While the Planet Ocean is resistant up to 600 metres, the Seamaster 300m has a resistance of up to 300 metres. This difference is crucial if you’re looking to achieve deeper dives.

Most watches in the Planet Ocean range are also Master Chronometer-certified, ensuring a high degree of precision. Another difference is the case size. The Seamaster 300m models have smaller cases, usually 41mm or 42mm in size, while the Planet Ocean’s are slightly larger at 45mm. While this may seem insignificant, it can make all the difference when worn on the wrist.

Both lines make use of the co-axial escapement movement, come with a helium escape valve, and offer outstanding timepieces that have been designed and produced with performance and quality in mind. They also offer the Super-LumiNova feature, which guarantees visibility underwater even in the harshest of conditions by allowing the indexes and hands to glow in the dark.

If you’re unsure whether a Planet Ocean or a Seamaster 300m is best suited for you, consider your lifestyle. For example, the larger cases of the Planet Ocean watches may be the best choice if you’re a professional looking to explore greater depths. The Seamaster 300m looks just as good in a wetsuit as it does in formal or everyday wear, making it a fantastic option for those seeking a fashionable piece that still offers a high degree of functionality and water resistance.

At Banks Lyon, we stock a wide range of OMEGA timepieces, including a vast selection of Seamaster 300m and Planet Ocean watches. Myles Harrison, our Lancaster store manager, is also an OMEGA Grand Ambassador, so you can be confident that he will be able to answer all of your questions on any model of this superb brand.
