A new, even more retro look for Omega's 1957-inspired dive watch.

2021 Omega Seamaster 300 steel black dial

Launched in 2014, the Omega Seamaster 300 – not to be confused with the more modern James Bond Seamaster Diver 300M – has been the brand’s vintage evocation of the original 1957 Seamaster 300. Still, its previous iteration (2014) was perhaps a bit too technical and sporty. Well, Omega has apparently understood that and for 2021, introduces an entirely revamped model. If the basics are still here, meaning a look inspired by the 1957 reference CK2913, the case, the dial, the movement, and most details are new. And there’s even an unprecedented bronze-gold version coming, in a one-of-a-kind alloy. Let’s have a first look, in the metal, at this 2021 Omega Seamaster 300 Collection.

Introduced in 1957 alongside the first Speedmaster and the Railmaster – thus creating the iconic Professional trilogy – the Seamaster 300 represents one of the brand’s most important and most influential watches. Its design, with its typical 2-part bezel – combining a polished metal ring and a black insert with a 60-minute scale – its broad arrow hands or its angular case, have been a source of inspiration for multiple models in the Omega’s history. The pinnacle of this retro inspiration came in 2014, with the Seamaster 300 that we’ve extensively reviewed here. There was no doubt regarding the quality of the watch or its impressive movement. Yet, the styling was a bit too modern, too sporty, too technical for a watch that was supposed to evoke the past. This year, Omega launches a new collection that will be thinner, equipped with a new movement (METAS-approved, of course) and with plenty of vintage charm to clearly differentiate this watch from the modern Diver 300M.

The steel Omega Seamaster 300

Before starting with the details, it’s important to mention that, in addition to the steel versions, Omega is adding a third iteration made from an unprecedented alloy, which stands out from the rest of the collection. This one will need its own section.

But first, the two steel models. The basics of the Omega Seamaster 300 collection have been kept, with a case that measures 41mm in diameter but is thinner than before, at now 13.85mm (vs. just under 15mm in the past edition). The case still shows the same angular design, with symmetrical casebands, no crown guards and flat surfaces top and sides. The lugs are adorned with a nice polished bevel on the side too, but nothing new here. The flat surfaces are polished while the casebands are brushed. Finally, there’s a new conical screw-in crown and water-resistance, as you’d expect from the name, is still rated at 300 metres. There’s a new, far more domed sapphire crystal too over the dial, once again enhancing the retro look of the watch.

Some evolutions are to be noted on the bezel and its proportions too. First of all, the dial opening has been increased from 29.5mm to 30.4mm now, and the bezel is thinner than in the past version. This makes the watch lighter and visually less bulky. Although the bezel still displays its distinctive coin-edge profile and 2-part design, the insert of these two steel editions is not ceramic anymore, but matte oxalic anodized aluminium (for improved resistance), with a cleaner, less shiny and more vintagey look. The 60-minute scale is super-clean too, with minimal graduations and a luminous dot.

For this new Omega Seamaster 300 Collection, the brand has also worked on the dial, with the same idea of retro styling and a sleeker design. As such, the brand has opted for a so-called sandwich dial made from two layers. The lower one is coated with vintage-coloured Super-LumiNova, while the upper one features cut-out areas for the recessed hour markers and numerals revealing the lume underneath. In a nod to history, these numerals are in the vintage Arabic open style, which appeared on early Seamaster 300 models in the 1960s. The base of the dial, available in warm black or blue (and matching the bezel’s insert), is matte and slightly grained.

The hands of this new Omega Seamaster 300 have also been reworked. The hour hand (with blue emission) still has its faceted arrow style, while the minute hand (with green emission) is a sword shape. The real news here is the lollipop seconds hand, with its tip filled with Super-LumiNova. Overall, the dial is cleaner, with only minimal literature – logo, brand name and model name – and no longer any references to the movement’s technology. Well done.

The strap or bracelet options are also new to this new Omega Seamaster 300. First is a thin, retro-looking leather strap closed by a steel pin buckle. The steel bracelet has been reworked, now with external polished links and a brushed central link (reversed compared to the previous edition), and its shape has been ergonomically adjusted with streamlined fittings and a thinner, polished/brushed clasp with fine adjustment.

Under the hood, it’s all about modernity though. The brand has equipped the watch with its Co-Axial Master Chronometer calibre 8912, replacing the older calibre 8400. If the architecture is basically the same, this new movement is now Master Chronometer-certified by METAS. This powerful and large automatic movement has a twin-barrel architecture with a 60h power reserve, a 3.5Hz frequency for its silicon escapement with co-axial technology and is, in addition to its certified precision, resistant to magnetic fields up to 15,000-gauss. It is visible under a sapphire caseback with a wave-edged design. The decoration is classic Omega.

For now, two steel editions have been presented, the reference with black dial on leather strap, and the reference with blue dial on steel bracelet. No doubt that other combinations (such as black dial on steel bracelet) will be available too. The prices will be CHF 6,150 on leather strap and CHF 6,450 on steel bracelet.

The Bronze-gold Omega Seamaster 300

The other real noticeable thing about this new Omega Seamaster 300 collection is the introduction of a third model, which is slightly different in design and finish from the rest of the steel models, but also has something special: its material.

Indeed, Omega is introducing a new patent-pending material named “Bronze Gold” described by Omega as  “specifically developed to produce a pleasing aesthetic and hue, while also offering a bronze alloy that could be worn with direct contact on the skin, thanks to its distinctive composition“. Used for both the case and buckle, the one-of-a-kind alloy is enriched with noble elements such as 37.5% gold, hallmarked as 9k, as well as palladium and silver, to create a unique colour that sits exactly between Moonshine gold and Sedna gold. Also, being more corrosion-resistant than traditional bronze alloy, it won’t get verdigris oxidation and thus will age slowly and retain its natural and beautiful patina over a longer period of time.

Although the watch retains most of the elements explained above, such as the 41mm diameter and shape of the case, some differences are worth noting. There are more brushed surfaces around the case, the bezel’s insert is made of dark brown and glossy ceramic, and the dial is made from solid bronze, in a dark brown colour with a patina that was created after a special ageing process had taken place. The sandwich architecture and the hands’ design (even though bronze-coloured) have been retained, except for the seconds hand with diamond-shaped luminous tip.

This Omega Seamaster 300 Bronze Gold (ref. is also powered by the in-house calibre 8912 and is worn on a brown vintage leather strap with a Bronze Gold pin buckle. It will be priced at CHF 11,500.

  1. As usual a great early write up on a new Omega. Monochrome Watches always seems to do this more thoroughly than other websites. As an owner of the current/old Seamaster 300 I am surprised to see a sandwich dial on an Omega as my watch has a sandblasted ceramic dial with laser cut outs for the hour markers filled in with Superluminova. This new watch seems to have adopted a full sandwich construction like a Panerai. My own research suggests this is the first ever Omega to use a sandwich dial but I defer to Monochrome Watches if I am not correct.

  2. @SPR – thanks for your comment 🙂 appreciated as always. As for the dial, it indeed is a real sandwich construction, and I’d say that it might well be a first for Omega. But like you, not 100% sure.

  3. Really nice.. fauxtina ruins it though.. when this faux vintage trend dies off this will lose a lot of its charm.. longevity is always a consideration when making purchases in the multiple thousands.

  4. Love that the Seamaster is getting slimmer! That’s still the one area apart from brand recognition where Rolex has a leg-up over Omega. If the thickness of the co-axial calibers could be reduced, that would certainly narrow the gap.

    I am torn on the use of aluminum for the bezel. Though I like the vintage vibe, I can’t help but feel that this is a cash grab to improve margins (assumption being that aluminum bezels are less costly to manufacture than those in ceramic).

  5. This is one of the few watches with ‘fauxtina’ that I think suits it – another being JLC’s U.S version of the Reverso Tribute to 1931.

    Nice to see Omega making an effort to slim down their automatic calibres. The steel on bracelet is a beautiful watch, and if I saw someone wearing it I’d give a little nod of appreciation.

  6. One niggle to add though, is that I hope it’s the warping effect of the crystal that makes some of the cuttings on the upper dial seem ever-so-slightly unequal in sharpness. But maybe it’s just me.

  7. Pros:
    1. Aluminium bezel (personal preference)
    2. Sandwich dial
    3. No date window

    1. Fauxtina
    2. Fauxtina
    3. Fauxtina

    …. shame the cons outweigh the pros on this one.

  8. I am praying this bracelet fits my outgoing reference, as the female end links and more agressive taper are absolute winners. Its not going to though is it…. 🙁

  9. IMO it’s a lovely watch! I do enjoy the cream lume (don’t even like calling it fauxtina).
    My only concern would be about the hight. @Brice is 13.85mm the height to the top of the crystal? Do you know what is the height without the crystal (or how high the crystal itself is)?

  10. @Brian – indeed, that’s the full height. The crystal is about 1mm higher than the bezel, so it should be around 13mm without crystal.

  11. Tnx for a great review.

    Wonder why no one adds the weight figure to watch reviews. anyone knows whats the weight of the watch?

    About the “Sandwich dial”. Is it a real Sandwich dial like Panerai or a shortcut to make it look like ?

  12. @Dave – thanks for the comment. As you can see, this article isn’t a proper review, but an introducing article. We shot the watches at the Omega HQ, in a limited period of time, and we don’t carry a weight scale with us when travelling… And about the sandwich dial, yes we’re talking real sandwich, two-layer construction (like Panerai)

  13. One update for potential buyers – I have been trying to get a blue dial version for close to 6 months and so far have not bought one. The reason is the absolutely rubbish bezel and low quality dial on the blue version. The bezel has far too much play in it being able to move it up to 2mm back and forth before the bezel ratchets onto the next half second slot. The bezels can also be moved up and down about 2mm on some watches suggesting that if you are not careful the bezel could be dislodged. As the bezel turns it sound tinny and cheap as well. The black dial version has the same issues to to a lesser degree. The dials of the blue version have discolouration around the cutouts for the numerals together with a “lip” where the machine used to cut out the numerals has clearly over cut and left a bit of debris still attached to the dial. The black dial version does not have this issue. Some of the new 300s also suffer from flakes of superluminova on the dials and crystals. Until Omega sorts out the quality of the new 300 I will not buy one.
