Omega Seamaster 300M Professional Review-Is it good in 2026?

The first thing that comes to mind when you hear Omega is probably SpeedMaster, or Moonwatch.  That’s for a mere second, because the next moment  you would probably think: Bond, James Bond. 

That’s  because Speedmaster was the first watch to be worn by an astronaut on the Moon, and also the marketing people at Omega did a pretty good job to promote the brand , notably the Omega Seamaster, that  has been featured as  the official watch of James Bond  in many movies, since the 90s. And, it will most likely be  in the future. 

But these models are not just the result of marketing done well. They also have tradition and innovation, Omega being one of the oldest watch companies in the world that still exists today. 

On review I have the Omega Seamaster Professional 300, and yes, I can see that the people at Omega love to name their watches in such a way that you’d say we’re meeting an Arab prince or Spanish macho lover with a much too long name. 

The Omega Seamaster 300 Professional ( ref. 210.30.42.20.06.001) is what you might call a luxury model dive watch, with a starting price somewhere around €6700 for the metal bracelet version. For the model with the rubber strap you can drop another 2-300 euro. 

We are of course talking about the official boutique price. Also, if you like dive watches, I published a comprehensive guide about dive watches.

Design and aesthetics

I’ll start by saying that, at least for me, this is the most beautiful Diver watch on the market. It’s up against heavy names like the Rolex Submariner or Blancpain Fifty Fathoms but I think the Seamaster somehow stands out because of its shape.

Case

With the 42mm case size , I can say that it wears quite well and doesn’t feel like a chunky watch, but if you’re interested in this model, the recommendation is to try it before you buy it. Especially since my wrist measures 17 cm . So I’m not exactly a landmark to take. 

The material used is stainless steel and at the moment I haven’t seen any scratches (I’ve had it for 2 years), at least nothing noticeable to the naked eye. Can’t say the same about the bracelet, but more in that section.

The case finishes are actually a mix, with brushed parts and polished parts. This mix gives it a rugged yet elegant look.

The Helium escapement valve is already the signature of the Omega Seamaster Professional 300M, you can recognize it from a post and the chances of mistaking it for a Rolex or other diver are minimal thanks to this valve. 

Opinions are divided, some are appreciative, others criticize at the top of their lungs. 

Personally I like it, I tried to imagine what it would look like without the valve… can only say I prefer it with.  

The valve is positioned at the 10 o’clock position and I’ll probably never use it, as 99% of the buyers of this model of watch will probably never use it.

The thickness of the watch is 13.6 mm – perfectly proportioned from that point of view, and the lug-to-lug measures 49 mm. When this model was announced in the version I have, which is the last one, people panicked because on the sheet the dimensions are not for everyone. 

But the situation calmed down, the angels sang again when they saw it in person and tried it on, because even though it’s big, it looks and feels smaller than it is. 

Dial

While we’re on the design section, I actually love the design on the dial, reminiscent of the waves of the sea, very carefully executed using laser technology. Of course, it was much snazzier if I said they were hand-crafted, but that’s not the case with the Omega, and it would  probably be more expensive. 

Even so, the effect of the dial is spectacular, especially in the color combination that I have, gray-blue, and especially when exposed to light that seems to play with the dial design. 

The hour markers are applied, not drawn and their edges are blue to match the overall design.

 At 12 o’clock we have two rectangular inserts , at 9 and 3 o’clock we have a single rectangle, and the other hours are represented by little circles.

At 6 o’clock we obviously have the date, which follows the same design note, and the background is gray, while the lettering is blue. You might think it’s hard to read, but luckily it’s not that at all, the contrast is very good and the fact that the hour markers are raised makes everything quick and easy to read.

 The hands of the watch also complete the look , being painted in a glossy blue that reflects the light in a great way, cut out in the middle so as not to take away too much of the beauty of the dial, and the edges have inserts of what Omega calls Super Luminova. 

And it’s really “Super”, because it emits a  blue light on the hour hand, and on the minute hand we have a fluorescent green.

 Also on the watch bezel, which yes, rotates, at 12 o’clock we have the famous upside-down triangle with a green glow-in-the-dark circle in the center. Unfortunately the rotating bezel does not have Super Luminova on the numerals as well.

Of course the dial is covered by a Sapphire crystal which has been treated with an anti reflective solution which surprise surprise really does the job very well. There was no question of anything else, especially since the alternative would be Plexiglas, and who wants that on a watch costing several thousand euros?  Probably those who are die-hard Omega Speedmaster fans.

Not infrequently I found myself staring at the watch face for minutes on end. And that says everything about the design. 

Case Back

Unlike the Rolex Submariner, because that’s its rival, the Omega Seamaster has an open case back- which means the mechanism is visible through the sapphire crystal glass. The mechanism isn’t an out of the ordinary beauty, but it looks pretty good, plus the fact that you can see it I’d consider just a fad. How often do I even look at the back of a watch? 

But it’s there, and if you’re interested in seeing the clockwork, this model fulfills your desire.

Bezel

Speaking of the bezel, I like it, but I’ve seen quite a few people criticize it. Especially when it comes to its rotation.

 Correct, I too find that it moves slower, and the cutouts on the bezel don’t provide a very good grip, but it makes up for it when it comes to the look it gives to the watch. 

The numbers on the bezel are painted white on a blue background, and the material used is ceramic. They are quite large, so they are easy to read. The ceramic and the color chosen give it a shiny look when light meets it, but nothing very garish. 

Overall I would say that for normal use, the time can be read very easily and very quickly. And that’s a plus, especially since there are watch models where you actually struggle to read the time. 

Bracelet

I seem to have overly praised the watch up to this point, and I’m relieved to find something to complain about. 

The bracelet design is okay. Nothing that steals your eye or makes you exclaim wow, like Rolex does with the Jubilee bracelet. The watch comes in several variants: stainless steel bracelet, Mesh or Milanese which is also stainless steel but with a much nicer design and of course rubber which is ok, but it’s rubber. 

The stainless steel bracelet has a cool thing, patented by them supposedly but found on many other bracelets from other manufacturers, by the name of Fold Over clasp, which opens the bracelet even more so you can put it on a wetsuit easily. 

The bracelet also has quick adjustment.  That means you can adjust the size of the bracelet without having to take the piece off. And it’s perfect especially since your hands swell or shrink depending on the season or how well you hydrate yourself.

Overall, it’s comfortable, but it’s spoiled by one essential thing…the buckle. God, I hate it! Big, cumbersome, annoying to wear and like a scratch magnet. The Omega logo’s nicely inset, but that’s about it. I always prefer the buckle on the newer Speedmaster. Unobtrusive, nice, and doesn’t seem to bother you when you wear the watch.. 

Otherwise like I said, it adjusts easily, the bracelet is ok-ish, and I don’t like the bracelet buckle. Which is why most of the time I wear it on a rubber strap. Something cheap, no name. 

When it comes to design, I’d say it’s a perfect mix of sporty and elegant. I find it works well with a suit, but also in a casual outfit. Still, it won’t compare to Ulysse Nardin Marine Torpilleur which we also reviewed when it comes to versaltility.

Durability and Quality of Omega Seamaster

As I already mentioned the watch is stainless steel, and on the bezel we have ceramic. The omega people say it is scratch resistant, and it is to some extent. 

There are no scratches on the case, but there are on the bracelet. Probably because it’s the most exposed to interaction with other objects, especially table surfaces.

But quality is clearly at home when it comes to this model. The sapphire glass does its job exemplary and the anti-reflection treatment is very good. Even in bright sunlight you don’t see any reflection. A big plus here for the Seamaster.

The official weight is 194 grams. I weighed it and it showed 186 grams, but that’s also because I took two pieces off the bracelet. That’s about where the weight is. 

With extended wear it starts to get annoying. More details you can see in the article A week with the Omega Seamaster 300M on my wrist.

Water resistance at home! 300 meters (1000 feet), it also has the Helium valve. Still, humans can’t withstand such depths without a proper protective suit. But it’s good to know that if you go under, you die and the watch still keeps time. 

Mechanism and Functionality

Omega Co-Axial Master Master Chronometer 8800- Told you  that Omega likes to give their products long names. 

But as long as the name is, so good is the mechanism. First of all it is METAS (Swiss Federal Institute of Metrology) certified, secondly it is COSC (Contrôle Officiel Suisse des Chronomètres) certified and that tells us that the watch has high precision and accuracy. 

Unfortunately at the moment I didn’t have the device to test it, but I noticed one thing. If I put it in the watch winder, it is the only watch that retains its accuracy.

 Ulysse Nardin Marine Torpilleur is still close to it. In contrast the Longines Spirit Spirit ZULU Time or Bel Canto C1 lose a few minutes. The latter even stops.

Omega’s 8800 mechanism is automatic, i.e. on hand movement the rotor moves and the spring tensions again. Nothing out of the ordinary, all automatic watches do this, and some are quite cheap. 

As for the power reserve, Omega tells us 55 hours, I honestly haven’t tested that but yes, it lasts longer than other watches I have. I’m still waiting for watches that go a week still. 

The mechanism isn’t very complicated, as I said it also displays the date at the bottom of the dial in place of the index that shows us 6 o’clock.

  It’s a relatively new position, because in the past on Omega Seamaster models the date was at 3 o’clock.  I personally think it looks much better with the new position 

The frequency at which the mechanism runs is 25200 , not the highest but not the lowest either. I also have to mention however that Omega states on their website that the mechanism runs above COSC standards, i.e. with an accuracy of 0 to +5 seconds per day. 

The truth is that it probably runs better than that. In a measurement I did some time ago, I had somewhere around +3 seconds per week. 

About the Movement nothing bad. Of all the watches I own, it clearly ranks…either 1 or 2 haven’t decided yet. The Ulysse Nardin isn’t bad either. 

Comfort and Wearability

As I already said, it’s not an easy watch to wear, but that’s only because of the buckle and probably the weight. 

However, the ergonomic design and the curved lugs somehow ensure a comfortable fit on the wrist.  The bracelet is not the most comfortable, the watch feels much better on a rubber strap.  

But it looks good, on the clear metal bracelet it’s also good to wear it with a suit as it gives it a sophisticated air.  The adjustable clasp helps a lot too, and for those times when your wrist feels swollen, you can increase the diameter of the bracelet in seconds. 

I’d say it’s a comfortable watch, but with the new Speedmaster bracelet or on a rubber strap. Of course, for a day or two the stainless steel bracelet doesn’t bother you very much either. 

Features and Technology

Certifications upon certifications! This is pretty much what we’re dealing with when we talk in general about Omega watches. After the aforementioned COSC and METAS certifications, we of course also have a Master Chronometer title. And Omega gives you the cards with all the certifications in the package. 

 And that’s not exactly easy to get. The watch has to pass eight tests, and it has to pass them all with flying colors. We’ve talked about those tests in this article. In short, the watch withstands magnetic fields up to 15,000 gauss. 

The Ceramic bezel has Liquidmetal markings and this gives it increased durability. And it shows, after 2 years I don’t see any differences or wear marks. It looks like day one!  

And again, the Super Luminova looks really cool to me and the combination of two colors, blue and green, gives it a nice look. 

Value for Money

I told you that the price is somewhere around 6700 euros, depending on the bracelet. But for that money you get a not good, but very good watch. Clearly it can be compared to the Rolex Submariner, in fact it is the only serious competitor to the Submariner.

It offers the same durability and accuracy but for less money and immediate availability. In the same price range you can buy the new Formex Essence Ceramica Dark Matter, which is a limited edition of 100 pieces per year, and the price is 4590 EUR

We’re not going to get into why the Rolex is more expensive, but we can say that the marketing there has worked like a Swiss mechanism. 

If you’re passionate, have the money and want a Diver, clearly the Omega Seamaster 300M Professional is a good choice, even if the name is too long! 

Box and packaging

Here again I have to praise the product. But it’s worth it, because Omega in recent years have paid a lot of attention to the box. 

It’s made of wood, very fine, the color I like very much and it opens with the push of a button. That button makes all the difference, it somehow gives you that premium feel. 

But the good part is not the button. It’s the fact that in the box, in the area where the watch sits, Omega have also fitted a little travel case. You pull it out of the big box and it closes like a locker, perfect for traveling. 

The materials inside are leather, or imitation leather, soft to the touch and light cream in color. 

In the box you also get three cards, which also come in a leather wallet. One card is for the international warranty (5 years), a Master Chronometer card on which you also have some METAS website login data. And the last card, I honestly don’t know what it’s for.

It says Pictograms on it, you have the watch reference number and the name of the mechanism. 

Overall, it is and feels like a premium watch and the packaging does not disappoint at all. For me Omega’s box is No.1 at the moment and has become a benchmark when talking about the boxes the watches come in. 

In closing I would say that the Omega Seamaster Professional 300M is worthy of its name, as long , as good as it is! 

From the packaging and box, to the watch you wear every day (if you can) the Omega Seamaster 300 is clearly a good choice.  It’s hard for me to say if it’s a better choice than a Rolex Submariner, on the sheet yes, far superior. But Rolex touches where the man is most comfortable…in pride. 

I created a complete comparison guide on the topic of Rolex vs Omega in which I explained which is the right choice!

You have Rolex, you’re somebody! That’s not to say the Omega doesn’t draw stares. It happened to me in Barcelona at the entrance of a club where there was a private party, a drunk guy standing in line next to me started asking me about the watch, then he loudly yelled You are rich, you are rich my man …even though at that party Audemars Piguet was standard.

Below you will see my rating, my personal ones and they reflect what I think and what my experience with the watch is. Feel free to give your own rating as well. I’m curious!
