You can use this comparison as a benchmark to determine which is a better dive watch. You will also understand which of these two dive watches best suits your personal needs.

Because of this risk, sometimes a deep sea diving kit needs to be replaced with newer or more reliable diving equipment. When you need to choose the perfect dive watch for your kit, you can easily be bombarded with information on the internet. By reading this, you'll compare two very popular Omega dive watches and see the information you need in an easy-to-read, quickly comparable format. Are you wondering why James Bond prefers to wear these watches? Check out the comparison below to get the insight.

The two post-2018 watch models we will be comparing are: 43.5 mm Omega Planet Ocean 600m Co-Axial Master Chronometer men's dive watch, model # 215.30.44.21.03.001. The Omega SM we will compare is the Omega Seamaster 300m Diver Co-Axial Master Chronometer 42 mm men's diving watch.

The good news is that many nice features have been added to both watches. First of all, they are both extremely accurate today, thanks to mechanical changes inside the watch. Let me also point out that Omega's models from a few years ago were also quite accurate, but now they have extremely high accuracy. The company has ensured that both now feature a more modern ceramic bezel, more legible numerals and hour markers, as well as a helium release valve.

Omega Planet Ocean

First of all, Planet Ocean is a great watch that fits any environment; He looks just as stylish wearing a tuxedo as he does when you're in your wetsuit and buried up to your neck in diving equipment. However, there are some specific features and unique details that distinguish Planet Ocean from the Seamaster. One of the first things you'll notice is that the hour and minute hands on Planet Ocean are arrow-shaped. It uses a high-gloss black zirconium oxide ceramic dial. They even engraved the word ZrO2 just below the middle of the dial, below the hour and minute hands. It also has more lume filling and a slightly larger dial. All of this makes Planet Ocean 600m much easier to read in low-light conditions such as the deep sea.

The PO is waterproof to 600 m / 2000 ft, which is a huge plus if you plan to go deep. Thanks to the helium release valve, Omega PO helps relieve the pressure on the movement, allowing the watch to sink deeper. Planet Ocean is waterproof to 600 meters/2000 feet, which is a huge plus if you plan to go deep. Omega took care to use different colors of lume filling for different parts of the watch. The dot at the starting point emits green color. Hour indexes glow blue. The hour and second hands are filled with blue lume, while the minute hand emits green light, just like the dot at the starting point. This makes it easier to read the time at a glance in the dark.

Planet Ocean is METAS and COSC certified. This means that the 39 jewel 8900 caliber movement that powers the watch has higher accuracy than a standard COSC certified caliber. After receiving the COSC certificate, it goes to METAS (Swiss Federal Institute of Metrology) laboratories for further testing on water sensitivity, durability and resistance to magnetic fields up to 15,000 gauss. The power reserve of the Caliber 8900 movement is approximately 60 hours.

This series also has a Chronograph version that comes with an additional stopwatch function and is powered by the Caliber 9900 self-winding movement; This is the same movement that powers the new Seamaster Diver 300m Chronograph Co-Axial Master Chronometer watches. So, in fact, the Planet Ocean Chronograph and the Seamaster Diver 300m Chronograph work with the same internal engine.

It is important to note that earlier models of the Seamaster 300m Diver produced until 2017-2018 are powered by older Omega caliber 3300 movements and are not METAS certified. On the other hand, newer 300m Diver watches produced since 2018 have the new METAS certification, just like Planet Ocean.

Omega Seamaster

The Omega Seamaster collection as a whole has been around a little longer than the Planet Ocean and comes in a wide variety of styles, shapes and sizes. The Omega Seamaster is a great-looking watch that you can wear on your wrist every day, and just like the PO, it can be worn with formal attire as well as with a wetsuit. For the average diver, this is an excellent dive watch and is also much more affordable than the Omega PO. On the other hand, in terms of features and technical details, it does not reach the level of Planet Ocean if you are a professional diver.

First of all, its waterproofness is only half that of the Planet Ocean, which is enough for most people. However, if you plan to go really deep on your next dive, this watch may be a bit underwhelming. Another noticeable difference is that the bezel on the Omega Seamaster offers less grip than that of the Planet Ocean. This series also has a Chronograph version that comes with an additional stopwatch function. These SM Diver 300m Co-Axial Master Chronometer Chronograph watches are actually powered by caliber 9900, which is the same caliber that powers the new Planet Ocean Master Chronometer Chronograph watches.
