Vetnov's detailed two-week review of the fourth-generation Omega Seamaster Planet Ocean offers a crucial early perspective on a watch that has sparked considerable debate among collectors. His insights into its wearability, design choices, and comparison to previous generations and competitors provide invaluable context for anyone considering this polarizing reference. This article distills Vetnov's initial impressions and the community's reactions, highlighting key aspects that define this evolution of the iconic dive watch.

As stated I have worn this one for 2 weeks since receiving it, and during that time I have read many reviews and watched many video reviews. The watch seems to be relatively polarizing as there are a number of varying opinions on it. Other than some comparable specs I am showing from this one and watches it might be competing with the rest are just my opinions.

Compared to the gen 3 PO 600m models the gen 4 is more than 2mm thinner and 42mm vs 43.5mm in diameter. The gen 4 is more similar to the Seamaster 300m models in thickness and diameter. In comparison to 41mm Subs it is about 1.5mm thicker while the lug to lug width is the same at 47.5mm (the lug to lug width was reduced 2.5mm vs gen 3 models). The 41mm Tudor Black Bay dive models have similar thickness to the new Omega (13.6mm) but the lug to lug distance is closer to 50mm.

As far as my opinions go I love this watch. It is very comfortable and doesn’t feel too big for 42mm. I think the reduced lug to lug width really helps with this. I like the lack of a date which can often unbalance dials. The simple matte black dial and orange numerals look great. The great looking orange bezel seems to be a nod to some of the gen 1 models that had orange aluminum bezel inserts.

The 3 things people were in most disagreement with.
1. The sharp angular case. Many people still prefer the more rounded case from previous models. I like the design, I don’t have an explanation. I just do. It looks great with the angled links of the bracelet imo.
2. The helium valve. There are many out there that feel like the helium valve has to be present for the watch to be a Planet Ocean, that it’s an essential part of the watch’s DNA. There are many that are glad it’s gone. All I can say is that I never would have bought one with the valve. In my opinion it is an unnecessary thing sticking out at 10 o’clock that serves no purpose since 99.999% of people will never dive to a depth in which it is needed.
3. The mirror polished center links of the bracelet. Most people thought all the links of the bracelet should be brushed, and this is one I agree with. They can catch light in a way that can be blinding, and perhaps more important they scratch easily. I’ve had this thing 2 weeks and there are scratches all over them. Personally I don’t care but if you like the watch and are bothered by scratches get the rubber strap instead of the bracelet.

Thanks for reading, pictures of the watch below and specs of the watches talked about in a format that might be easier to compare.

As an owner of the 2500, PO Chrono and the PO GMT I like SHOM like angularity of the case. I was a bit put off by the bracelet when I tried it on. I really wished that they had addressed the valve issue in the way they did with PLOPROF or Rolex did. I never minded the extra crown. All of that being said my ideal iteration would either be a ceramic version with a rubber strap, the “Bond” mesh bracelet with steel and I would like to see a gradient fume style dial…something really distinctive so I

In my experience, the best watches I have owned are polarizing in design. My opinion relates to AP watches such as the Montoya, Survivor, and Alinghi. Quite a bit of dislike and slandering of these models when they were released. But, over time, many of the naysayers do their 180 and end up buying the watch themselves. I always find that quite amusing. This updated Omega is different, but I applaud the brand for being bold and evolving the timepiece. I happen to like straight lines and angular s

It seems to me new releases often come with initial negative opinions (Cubitus and Land Dweller are recents that come to mind), but with time they can gain traction and become a lasting part of a brand’s collection. I know new models can also be flops but big brands don’t usually make such egregious mistakes.
