The Omega Seamaster Planet Ocean 600m at 43.5mm is no small watch, even for a 600m dive watch it is on the larger side. But it is very wearable on the Omega rubber strap or a nato strap, while the bracelet adds a lot of heft and for those with a smaller wrist it’s a bit uncomfortable. If you’re looking for a watch that you know you want to take anywhere the Planet Ocean is a great choice.

The master chronometer caliber 8900 beating inside the Planet Ocean is anti magnetic to 15,000 Gauss which is the magnetic power of an average MRI machine, so no need to worry about pesky magnetism. I have worn my Omega in all kinds of environments from harsh Minnesota winters reaching down well into negative temps to Minnesota summers hiking and canoeing. On a 2 week trip to the B.W.C.A., a canoe area in northern Minnesota along the Canadian border, I wore the Planet Ocean all week and it got some abuse, from portages walking through mud to swimming alongside waterfalls. At the end of my trip I relaxed in a sauna and my Planet Ocean was on wrist and it did just fine going from the sauna to jumping in the water immediately after leaving the sauna. Over the 2 weeks of wearing it 24/7, it only gained 4 seconds.

The ceramic bezel with rubber and liquid metal insert is very legible and the rubber insert adds a nice pop of color and while it is not a great dress watch it is very casual and wearable but it does not go under the cuff. The build quality is very nice and the bezel clicks solidly and the movement winds nice and hacks and the date window is executed very well. While the helium escape valve is very divisive, I think it adds a nice little flare and is a good conversation starter. One of the major downfalls of the Omega Seamaster Planet Ocean 600m is the thickness, size and weight – it is comparable to a large G-shock with some weight. The Planet Ocean is a great watch and suits any environment.
