CHECK OUT THE WATCHES I CREATED: www.ebay.com/str/hoglundandsonswatches

The P.O. is the higher end watch and much classier! I feel like the P.O. is their flagship diver and the 300M is their entry level diver. I also much prefer the P.O. hence why that’s the watch on my wrist as I type this. The 45.5 chrono version with the liquid metal and their new movement which keeps absolutely amazing time as well it should. The 300M is a nice watch but the P.O. is just nicer in every way to me. Rick

I tried on the 300m diver last night and loved it. Way more than I thought I would. It’s on my want-it list now! Thanks for the video!

There are enough differences between the two watches to continue having both of them to be available. Both are great watches

Seamaster 300. Love the dial & on the rubber strap, silver/ grey dial.

Great comperison. Thanks dude.

Great review & comparison! I don't think these two really will end up competing or cannibalizing eachother's sales though. It's like Rolex selling both the Sub & the Sea Dweller ranges, while the "lesser" watch may actually present a better value proposition, some people just want a watch that they know is the most expensive (similar to cars with the Mercedes 63 AMGs vs the 65 AMGs) or just more capable even if neither of these watches get taken to their maximum depth range. And there are those little details that set the PO apart, like the white gold incedes & hands, liquid metal bezel, more metal in general (including on precious metal options). It'd be interesting to see what Omega does though when they update the Planet Ocean so they can widen the gap between the two.

The planet ocean has a much better build quality in my opinion. Built like a tank. The bezel action is much much better too. Tried both, kept the planet ocean.

I prefer the Planet Ocean. A much better looking watch and I think it will never be discontinued as you believe

Impossible to choose between these two. Both magnificent timepieces. Looks, technology, quality. Everything is so perfect.

Well, OMEGA has started the war against competitors. Super high quality ‘certified’ merged with history in a well studied prices. So, let’s talk about the difference between new Diver 300 and Planet Ocean. In my humble opinion, the main difference is the taste of each design. Diver 300 mainly for people who love OMEGA and the iconic design of James Bond Watch. The Planet Ocean is for mature people who probably older in age but have higher experience and really want to take their watches to every activity they do. It’s like supporting Brazil or Germany in the World Cup. This might sound silly but let’s wait and see where OMEGA will take the New Planet Ocean to. Many thanks and happy New Year 2019

The Planet Ocean's bezel is not just ceramic. It is also Liquid Metal which is superior to the enamel-filled ceramic on the 300. I am not sure that's worth $2k, but it is a significant difference.

I own the 8900 planet ocean and love it. It is chunky and looks solid and of very high quality. My wrists are fairly average in size and it looks great. I think the 300m would be too small for many, unless you have small wrists or want a smaller watch. The 300m also looks more like a sports watch where as the PO looks more classy in my opinion. I also like the sapphire case back which I don’t think the 300m has? Both watches are decent and of good quality, but the PO wins hands down for me.

Happy New Year & great review! one correction, the previous iteration of the 300m has screw in links as well. One dissapointment with the new 300m is that Omega actually makes a adjustable clasp that is much more compact than the one on the new 300m that I purchased for the previous iteration that's much nicer.

Happy New Year. Agreed the 300m is such a high Tec quality and versatile sport/dress piece. It boosts just amazingly visibility to the indices and hands - making it one of the easiest dials to read in the field you can find anywhere-. if you like the dial design - it just can't be beat for anywhere near the price. Planet Ocean is gorgeous also- but some loss of dress versatility. I Love both. Thx again.

3:00. Finding it odd that the PO remains in the Omega line-up..... Seriously!?!? They are totally different watches and both deserve to remain. Following your logic, Rolex should also discontinue their Deep Sea line.

Before we weigh the PO, we go to the gym, do weight training, and whine. I choose PO over Diver 300 following Rolex. I'm still wearing a PO and I'm satisfied.

i strongly believe the planet ocean should stay in the collection as their differences go beyond just a difference in depth rating which for me at least is already iportant let alone other factors..its like saying oo there is the sub so we dont need a sea dweller

I was thinking about the PO before getting the Seamaster 300 until I saw them both in person. The Seamaster has a more appealing look. I didn’t think I would like the wave dial but I fell in love with it. All the divers on the market look the same, black dial, different hands but no distinction between them. The wave dial pops and the way it plays with the light... just stunning. As the Rolex vs Omega. Sure you aren’t getting the name but the omega is a far superior movement with newer features. Also good luck finding a Stainless steel submariner! The corporate approach to control the market turned me off.

Diver 300m is a dress diver, Planet Ocean a tool diver( which also looks fantastic)

I tried on both about 3 months ago. Whilst the planet ocean has a more brutish tool like bracelet that I like, I would go with the 300m as it is thinner and will fit under shirt sleeves far better. 300m is lighter as well. I have an 8’’ wrist and found both to be very comfortable.

Back in 2008, I had the exact same decision to make. Actually went for a 300m,but came you with a PO 42mm. I had the PO for 2 years before flipping due to a house purchase. It was a great watch which fitted under a shirt cuff no problems. Back then I think the PO looked smarter, but not sure in 2018. Black 300m is very smart. On the PO, my crown got a slight debt and I don't like the HE valve on either. The PO I had the seahorse embossed back, which on a hot day rubbed my wrist bone and irritated skin. Display case back today should be fine. I occasionally look at photos of my old PO and want another. Then I see and Aqua Terra and realise that's the best choice for where I am in life now.

Happy New Year 🎉🍾

I have both the 300M in green and the PO in 42mm with the orange applied 12,9 & 6. They are both incredible.

I think the planet ocean 39.5mm looks much better than the larger one featured in the video, at least for my smaller wrists! It also looks a bit more discreet as the case is much thinner.

I had a PO for a few years. A little over a week ago traded it in for a OS 300. I picked up a black dialed gold accented one on a rubber strap. I think the slimmer profile appeals to me and while the PO was big, bold and absolutely fabulous in many ways, I prefer the new watches I now have (I also purchased a Speedmaster along with the Seamaster)

I have the planet ocean. Absolutely love it!

Getting the bracelet is almost always the smart move when buying a watch.

I have the 600M PO. Not sure why, but I really don't like the skeloton hands on the 300. I really like the arrow hands. Personal opinion and I am sure the 300M is a great watch.

Planet Ocean by a mile. Better movement, better bezel, liquidmetal marks are technologically cool and more elegant comparing to contrasting enamel marks of SMP300, even omega logo and dial printing are more refined. Outstanding style connecting classic seamaster and modern high class dive watch. While SMP300 is a young dude in fancy suit who loudly wants to mark his presence, PO is super cool, timeless, James Bond-ish kind of a guy in tuxedo who doesnt't have to prove anything to anybody. Anywhere.

As a proud owner of both these wonderful watches the PO with orange bezel chrono & the Seamaster in blue dial. I can tell you first hand the PO gets easily 5x's more compliments than does the Seamaster. However, I adore both co-equally. Lastly, my first Seamaster was a 99' blue with the previous wave dial. The newer wave design has much more pop to it. The 99' marketed as the 007 was much more understated.

The Diver 300m (previous version) is my dress watch. I wear it to work with a button-down shirt and tie. The next Planet Ocean should be more of a true tool watch. Omega should offer a version with a dull matte finish or black coating, rubberized bezel, 1200m water resistance, extra shock-proofing--something to compete with the IWC Aqua Timer and the Rolex Sea Dweller. Then there would be no problem with it being big and thick.

I prefer the Planet Ocean, especially in 39.5 mm size. Better bracelet, better legibility, better hour and minute markers, better depth rating and cleaner dial. The Thinking Man’s Seamaster...

you forgot to mention the jumping hour of PO 8900. I am getting 39.5mm version of PO, because of small wrist. This 39.5mm PO shares the same caliber of Seamaster 300 (the difference is the date's location). Of course, this doesn't have jumping hour feature. LOVE this video.

The Bracelet versions of Omegas have been about $100 more for quite a few years now...AND you can purchase one later, although more expensive. Tudor bracelets about 800-1000 more...and can't seem to buy a complete bracelet from Tudor no matter what the price. Omega IS COMPETING quite well. Planet Ocean will not be discontinued. If you look at the sizes, they are staggered between 300M and PO. Designs are distinctly different. Your value assessments are incorrect. PO has retained value as well as ANY 300M. Many people are still purchasing the glossy lacquered dial 300M as they find the "laser wavy" garish. So the PO becomes more viable as it has the smooth dial.

Getting the Diver in blue!

Thank you for the comparison....I love the diver but not so much the bracelet....I may change it for leather one Is it possible to get a planet ocean bracelet on the diver? It may work beautifully together even if you loose some of the diver dna

The planet ocean for me

how durable is the enamel on ceramic ? will it fade like those black paint on steel bezel on some other watch ?

Are they both fitted with adjustable clasp?

They have a 43.5mm no date smp now as well. Personally I think if the smp still had no wave dials the po would be made redundant. Nobody really needs 600m especially considering it creates so much bulk

Put the 300m dial on the PO, get rid of the skeletonized hands and I’m sold. Love the PO bracelet, and bezel.

Omega should continue both lines, they are quite different in styling. PO is more masculine and tougher, while Seamaster 300M is more sporting and casual, my views. Have PO 232.30.42 from 2014 on bracelet and recent 2018 Seamaster 300M black on NATO, and love them both.

I wish the Diver 300m had the Caliber 8900 movement with the independent hour hand. Very handy for travel (remember traveling?).

Previous gen SMP beats everything!!

The hour markers on the dial are made of white gold and that is part of extra cost

I think the Omega Seamaster (2018) is an elegant watch. Price notwithstanding, it is exquisitely crafted and designed for everyday use. Lighter than P.O. but very stylish. While the bracelet exudes charm, the black strap portrays ruggedness.

I have a 7 1/4 inch wrist, and find it quite easy for the 43.5 mm Planet Ocean to fit under a dress shirt cuff. Some shirt cuffs are tighter from the manufacturer, but an alteration shop can easily and cheaply move the button placement slightly to help accommodate the size. Really it comes down which watch you like more, and if a taller or thinner watch is your preference. The thicker watch will have more wrist presence, and in my view maintain a bit more of the classic charm of the 1960s Omega divers and despite its size, it maintains a more elegantly understated design language. The bezel of the Planet Ocean is also slightly more dressy due to the shiny liquid metal ceramic material.

The 300m is $5200 on bracelet. Not sure if Omega adjusting pricing at some point, but i've never seen it at $4,850 on bracelet.

I always wonder if you use one bare hand to touch watches, why bother to wear a glove on another hand? is there any reason? I am being serious to ask this.

I've been thinking about buying Planet Ocean 43 mm but there are some issues with its 8900 movement. It has an hour hand changing feature and if you use it often the wheel is worn and needs to be replaced. Google it. Therefore my choice will be a new Seamaster.

I use to HATE the seamaster. It was always the watch people got cause they couldn’t get a sub. This new edition is nice! The first omega I actually liked. The helium valve could be overlooked as the overall design aesthetic is great. The wave pattern also adds visual interest.

I like the look and feel of the planet ocean a bit more but it is so darn thick. I am a one watch guy and I just couldn't use it daily. Not a huge fan of the bracelet on the Bond style 300 and I preferred the model before this one. It was more quiet and looked a little more classy. The wave dial thing is just not my taste although I understand is roots and respect people that love. In the end, the 300, bond-style divers, are absolute Legends whether you like them or not. The planet ocean has quickly become a modern-day classic as well. Buy what you like and enjoy!

Look at Rolex chap, submariner, deep sea and sea dweller so how is this any different? These are aesthetically more different from the Rolex variants as well. Both have a place imo.

The 300 is a bit more flashy than the 600.

i love OMEGA both are excellent watches. i have seamaster 300m sedna gold.

isnt the bezel on the po smoother than smp 300 because of the liquid metal technology?

I own the 600m Planet Ocean . I love it its a big boy but I like that bulky style. I think it would be nice if they discontinued them I have a feeling over time my 600m would gain in Value.

I had this same problem so I bought both. My Seamaster 300 is black and my PO is blue. For the price there aren’t two better watches on the market.

I have both, PO superior quality but love the 300m too

The Seamaster 300m was my dream watch. God gave me the opportunity to buy it, I am a grateful guy. It is fantastic, I got it in blue.dial with the bracelet. Then I bought the new rubber folding clasp strap!! I also prefer the 300m vs the Planet Ocean due to its size and price!!

PO yes 2x water resistance, movement has forward and backward hours, more power reserve from 2 barrels, and has a totally different feel when wearing. Silly they are both in the Omega lineup? Edit: I retract my somewhat snarky comment about subscription, but I still respectfully disagree: in my opinion, the PO and SMP300M are 2 very different watches and both deserve to be in the Omega lineup.

When was 13.8 thickness thin? Good day sir.

I tried them both on, the PO won hands down. I ordered it right there. The 300 just didn't do it for me IMO

i like'um both !

Good review. Never heard of a suit shirt, though I have heard of dress shirt....

Not sure where you’re getting your info from, but the 300 (‘93) is a much older design than the PO (‘05). I have both of these watches in regular and chronographs, and love them all, but the POs are in a different league; that’s why they’re more expensive. Everything from the bezels, the applied Omega logos (rather than painted on the 300s), and twice the water resistance, put my POs out in front of my 300s. I recommend the 300s for people just getting into watches or maybe buying their first nice watch even. The more experienced watch guys will notice all the little, and big, things that make the PO Omega’s premier dive watch offering. You’re definitely getting what you pay for with the POs. Also, my new 2020 PO absolutely SMOKES my old one that I purchased in ‘09. Same with the new vs. old 300s, but even new 300s aren’t in the PO’s league. 300s are better than Tudor BBs, but POs are taking a serious run at Rolex Subs.

The Planet Ocean will be updated soon, I quess. Omega will step up their game on the Planet Ocean because they need to be ahead of the competition. Tudor and the Rolex Sea Dweller for instance. Not talking about the Rolex Deep Sea because that is a complete other level but the 1200m depth rating of the Sea Dweller will be a good reverence point for the Planet Ocean series. Another positive point for the Planet Ocean is the case size. I prefer 43mm or 44mm watches so the 300m diver will probably too small for a lot of people.

Aspect most people glance over e.g. the shape of hte index's on the face. Are they all dots? are they rectangles? Are the arms solid or "see-through/skeleton arms"? IMHO we should want "rectangular " shaped index's for easy/quick recgonition in day or night. For this reason I'd go with the Planet Ocean over the 300M Pro... Water resistence ratings---helps sell watches...and companies are always one-upping each other Why there are so many depth /wagter resistence ratgings. Most owners/wearers don't dive :)) And having "good LUM" is imporant...here i think tag's are the best....you don't want to struggle or sped more time than needed to glance the time....

I had the planter ocean 43.5 blue with blue strap. It was a really nice watch. I wound up selling it and once this seamaster came out I waited for the blue on bracelet. It’s such a nice watch. I don’t see a point in the planet ocean anymore. If you hold side by side and look at the price difference. There is nothing that says the planet ocean should cost that much more

The PO is actually the newer of the 2 lines, by about 10 years.

I really do not like the skeletonized hands on the Diver 300m. Put the same hands on that as on the Planet Ocean, and I would have considered the 300m diver. Instead I bought the Planet Ocean.

Wish the Planet Ocean was in 42 mm , with the micro adjustment on the clasp

you are wrong on the age of the watches, the seamaster 300 has been around since at least the mid to late 90s and its been tweaked like the rolex sub over time , the planet ocean has been around for less time and has also been revamped over time, I have 2 seamaster 300s and will eventually get a po but there is no point discontinuing either as they are both very iconic watches in the watch community

They’re both awesome but the Planet Ocean is the way to go. In a way the 300 still looks a bit like a Sub homage whereas the PO is it’s own wonderful design.

There’s a huge array of very similar Seiko divers, so why not Omega?

Per me Planet Ocean

Bracelet are very different.

I want the 300 metre diver now

Seamaster 300 diver wins for me

If they release a 300m Seamaster GMT it will be a killer

I don't like the wave dial or bracelet for the 300m. Otherwise I like 300 better.

Why are you wearing glove on one hand and not the other? Your right hand is finger printing all the watches lol

Why is there so much ambient noise?

Diver 300m = For the Boys Planet Ocean 600m = For the MEN! Questions?

Dude, what he hell r u talking about? Why would omega discontinue the planet ocean? Has Rolex discontinued the sea dweller and he deep sea? And those watches run on basically the same movement with basically the same dials and, hands, bezels, bracelets and similar aesthetics in general. The PO is entirely a different watch than the seamaster and as such appeals to a different clientele. Some omega fans may even own both. By your logic Tudor should not sell the Pelagos and seiko should limit their divers to the 007

Was at the Omega store last night fully intending to buy the 300. Walked out with the Planet Ocean. Bracelet much better design. I have a large wrist so size actually fits me fine. Quality of Planet Ocean seems better as well. Love my Planet Ocean!

On the left when you are thirty, on the right when you are forty five. I have the second. 53. Cool watche

Hopefully, for Omegas reputation and market, they keep the new model in time and make a good competitor against the Rolex Sub. One negatve thing that Omega used have(70s) was the lack of real watertight watches. Hopefully this is only in the past. Rolex was by far more reliable with their Oyster cases. That Diver 300 looks outstanding. I own a vintage Sub since 1976.

I want the Diver 300M on the PO bracelet. Come on Omega

Or the new Spectre Seamaster 🤔

Nobody talks about the Aqua Terra

The 300 looks much better, but its to big for my. i prefer 39-40 mm

The Planet Ocean is a much better watch overall. Also the steel bracelet on the Diver is really bad, they should've given the Diver the same bracelet as the Planet Ocean.

That PO is thick as hell...will sell mine and will get that SMP in black or white. Lol

Hands down the new 300m

Seamaster bracelet is fugly. I'd take planet ocean. Also, the hands are more visible on the planet ocean. I'd take the planet ocean for sure.

When it comes to watches, I think rubber is a no-go.

Simple, you’re talking Brosnan James Bond or Daniel Craig, I think we all know which is better.

Wow the 600 looks twice as thick as the 300. The 300 looks more balanced.
