Omega is a watch company that has been around since 1848, giving the brand nowadays a very rich history. With over 170 years’ experience in watchmaking, you can expect that they have learnt and mastered the art of watchmaking. Alongside the history of the company, they have been making and selling the Seamaster since 1948. In 2005, they released the Omega Seamaster Planet Ocean, creating a new line of the model Seamaster. Eleven years later, in 2016, when the Planet Ocean was most recently updated, Omega announced that the Planet Ocean series would be the first Seamaster’s to be certified as Master Chronometers. This watch was made for collectors, avid timepiece lovers and adventurous individuals. Alongside the elegant style of this watch, the capabilities are what sets this model apart from the other Seamaster professional models such as the SMP 300 and the Aqua Terra. 

Quality born of long experience

When you think of an Omega watch, the first thing that you think of is the quality of the design and build. Omega is notoriously known for building some of the most durable watches on the market. If we look at the Seamaster Planet Ocean 43.5mm, we can see that the case is made from very high-quality stainless steel.

This has been done because this watch needs to be robust for the diving expeditions that this watch is designed for and even for day-to-day use. This ensures the buyer that no matter the test, the watch will be fine and can be worn with full confidence the Planet Oceans will last the test of time. 


Looking at the size, 43.5mm is the perfect size for maximising the capacity of the watch. With a unidirectional rotating and a ceramic insert, this is not only helpful for those who go deep sea diving but also for those who want an eye-catching watch. The glossy shine and finish of the case and ceramic gives the watch that dressy look so you can easily dress it up for an occasion should you wish to do so. 


Most may think that it would not suit their wrists at this size as other watches tend to be around the 40mm mark, however the clever Omega designers have made it wear more like a 42 or 41mm watch. Dive watches are known for usually being too bulky and big, however Omega have managed to create a timepiece which has the capabilities of being one of the best dive watches on the market, while also making a very elegant watch that can be used as a casual or dressed up watch.

When talking about the features of the watch, it is hard not to talk about the dial and the hands. The timepiece features a captivating dial that combines functionality with elegance. The bold and legible indexes and hands are coated with Super-Luminova, ensuring optimal visibility even in low-light conditions. The date window at 3 o'clock adds a practical element to the timepiece, enhancing its versatility for everyday wear. Seeing that this is a watch developed for deep sea diving, the water resistance of 600m is built for aquatic adventures at great depths of the oceans. 


With a water resistance of up to 600 metres (2000 feet), this ensures that it can be put to any test and pass with flying colours. This timepiece is a trusted companion for professional divers and water enthusiasts who are willing to look amazing whilst wearing the Omega. The helium escape valve further underlines its suitability for deep-sea exploration. On top of this, the watch is this sub stable for showers and swimming pools as well, making it a watch that has no need to be kept away in a box.

At the heart of the Seamaster Planet Ocean 43.5mm beats Omega's Co-Axial Master Chronometer movement, a hallmark of precision and reliability. The Seamaster Planet Ocean is equipped with METAS-certified co-axial calibre 8900 that you can see through the sapphire case back. 


The self-winding movement not only ensures accurate timekeeping but also has been certified by METAS, meeting the highest standards of accuracy, performance, and magnetic resistance. This again goes to show and prove time again that Omega is more than committed to producing watches that can cope in the most extreme conditions.

This gives you the confidence to wear your Planet Ocean whenever and wherever, and whilst most would say that these dive watches are never really going to be worn for their purpose, it is still nice to know it can do it. Not to mention, if you are into diving, even at shallow depths, it is never a bad thing to have a watch that is more than capable of handling the depth, so you’ll never have to worry about it. The movement's resistance to magnetism is especially handy in airports where your watch passes through security as it can sometimes happen that a watch starts to lose time due to its exposure to the magnetic field in the airport security section. However, this is of no concern to the Planet Ocean!

Unique features for a versatile diving machine 

Beyond its classic design and impeccable craftsmanship, the Seamaster Planet Ocean 43.5mm is equipped with modern features that set it apart.
