Omega Planet Ocean VS Omega Seamaster

Which is a better diver's watch?

You already know that the difference between owning the right equipment and the wrong equipment in professional diving can be a difference of life and death. Because of this risk, there are times when a deep sea dive kit needs to be upgraded with newer or more reliable diving equipment. When you have to choose the perfect diving watch for your kit, you can easily experience information overload on the web. By reading this you will be comparing two very popular Omega diver watches while seeing the information you need in an easy to read and quick to compare format.

You will compare the Omega Planet Ocean VS Omega Seamaster and use this comparison as a benchmark to determine which one is a better diver's watch. You will also figure out which of these two dive watches is the best to suit your individual needs.

The PO watch that we will compare is the 45.5mm Omega Planet Ocean 600m Co-Axial Master Chronometer Chronograph Men's Diving Watch model # 215.30.46.51.01.001. The Omega SM that we will compare is the Omega Seamaster 300m Diver Co-Axial Chronograph 44mm Men's Diver Watch.

 

Omega Planet Ocean

For starters, the Planet Ocean is a great all around watch and will look as great while you're wearing a tuxedo as it does when you're in your wetsuit and up to your neck in dive gear. That being said, there are certain specifications and unique features that differentiate the Planet Ocean from the Seamaster. One of the first things you may notice is that the hands on the Planet Ocean are arrow shaped. It uses the very glossy black zirconium oxide ceramic dial. They even engraved ZrO2 just under the middle of the dial below the hands. In addition, is has a more luminous fill and a slightly larger dial. All the above makes the Planet Ocean 600m much easier to read under low light conditions such as the deep sea.

The PO has 600 meters / 2000 feet of water resistance which is a huge plus if you plan on going in deep.  With a Helium escapement valve the Omega PO helps to release pressure on the movement allowing the watch to go deeper. The Planet Ocean has 600 meters / 2000 feet of water resistance which is a huge plus if you plan on going in deep. Omega made sure to use different colored luminous fill for different parts of the watch. The starting point dot emits a green color. The hour indexes give off a blue light. Hour and seconds hand give off a blue colored luminous filling and the minute hand emits a green light just like the dot at the starting point. This makes it easier to read the time at a quick glance when it's dark.

The Planet Ocean is a Master Chronometer. This means that the 54 jewel caliber 9900 movement which powers this watch has more accuracy than a standard COSC certified chronometer like the Omega caliber 3300 movement found in the Seamaster 300m Diver. After receiving the COSC designation it goes to the labs at METAS (the Swiss Federal Institute of Metrology) for further testing on its water precision, resistance, and resistance to magnetic fields up to 15,000 gauss. The calibre 9900 movement has a power reserve of approximately 60 hours.

Omega Seamaster

The Omega Seamaster collection, as a whole, has been around a bit longer than the Planet Ocean and comes in many styles, shapes, and sizes. The Omega Seamaster is a great looking watch and like the PO can be worn with a wetsuit as easily as in formal wear. For your average diver, this is the perfect diving watch and is also much more affordable than the Omega PO. On the other hand, in terms of features and specifications, it doesn't measure up to the Planet Ocean if you are a pro diver.

For starters, the water resistance is only half of that of the Planet Ocean and that is enough for most people. However, if you plan on going real deep during your next dive this watch may fall a little short. Another noticeable difference is that the bezel on the Omega Seamaster has less of a grip than that of the Planet Ocean.

In terms of accuracy, this watch is a COSC certified chronometer which is great but compared to the PO this again comes up a bit short since the Omega Planet Ocean is a Master Chronometer which means it has more accuracy, more water resistance and better resistance to magnetic fields than your run of the mill COSC chronometer.

PROS

Magnetic Resistance
Si14 silicon balance spring is magnetic resistant
Sub Dials
Extra sub dial exclusively for small seconds
Bracelet
The Seamaster 300m Diver Co-Axial Chronograph has a steel bracelet with a nice polished & brushed finish
Price
The Omega Seamaster is more affordable than the Planet Ocean

CONS

Water Resistance
The Seamaster 300m has a great water resistance but it pales in comparison to the Planet Ocean 600m which has twice the resistance.
Single Barrel Movement
The Seamaster has a great movement (Omega caliber 3300) but it doesn’t compare to the double barrel Omega caliber 9900 movement that is found in the Planet Ocean.
Case Back
Solid stainless steel case back has a seahorse stamped onto it like a medallion. Most people prefer a transparent case back where you can see the action of the mechanical movement.
