Omega Seamaster 300

This is the watch we’ve all been waiting for since Omega started to tease us via their Facebook page. We already did a guess some time ago (here), but now we finally get the chance to try the watch and see it in the flesh.

Based on the original Seamaster 300 CK2913 from 1957, Omega introduces the new Seamaster 300 Master Co-Axial in a number of different flavours. The name Master Co-Axial – as this confused a number of people – is referring to the anti-magnetic movement. Omega introduces 69 new watches with 8 different calibers that will carry an anti-magnetic movement based on the > 15,000 gauss movement they introduced in the Seamaster Aqua Terra last year.

Omega Seamaster 300


140327_DSC_9117This Seamaster 300 has a caliber 8400 movement (8401 for the one with the red gold rotor) inside. This is one of the 8 new calibers that Omega is using from now on.

140327_DSC_9111As you already could see on the teasers and in our previous article, the dial of the new Seamaster has a layered-effect that people also refer to as being a sandwich dial but that is not the correct association. The hour markers are lasered and then filled with Super Luminiova. This Super Luminova has a yellow-ish patina like color that really suits the watch and gives it that CK2913 look. The ceramic bezel with LiquidMetal diving scale also corresponds with the original bezel on the 1957 Seamaster 300, appareance-wise that is. The new technology makes the new bezel practically indestructible.  The broad arrow hands are also filled with matching coloured Super Luminova.

Black ceramic is also the material Omega used for the Seamaster 300 dial. It contains a sand-blasted finish to get the ‘vintage’ appearance.

140327_DSC_9108The Seamaster 300 comes in 6 different versions. Steel, titanium, bi-color in steel/gold and titanium/gold, gold and platinum. The stainless steel version with black dial and bezel  has a 5000 Euro price tag and the titanium version with blue bezel and dial has a 6000 Euro price tag. We feel this is a competitive price, offering a lot of watch for the buck (Euro).

The gold models contain the Omega Ceragold technology for the bezel. This technology allows the growth and bonding of 18 carat gold in ceramic.

All models have a bracelet with polished center link and with a patented rack-and-pusher clasp.  Finally Omega managed to produce an easy-to-use resizable clasp with 6 different positions. You will only need to open the clasp and press the ‘push’ button and slide the inner clasp to the desired fit.

We are confident that this new Seamaster 300 is a winner and can’t wait to give it a spin for an in-depth review. More information can be found on the Omega website.

    Nice preview guys! Any word on the thickness of the watch?

    • No, we didn’t measure that to be honest. However, we didn’t notice anything awkward.

  • M@ster

    Nice write up ! Would you recommend the blue Titan or black SS ?
    I prefer the black over the blue dial but also prefer titanium over ss

    • Thanks for the nice comment! Personally, I would prefer the stainless steel one with black dial and bezel.

  • MikeInFrankfurt

    Thanks for publishing…I’ve been waiting for more info on the blue model. I think you were first! See you in Basel!

    Great looking watch. Will make a nice companion for my 1958 Seamaster 300. What’s the diameter?

  • Jack

    Love this one!

  • Jay

    now if only it had a date display itll be perfect for me

    Is the Rose-gold rotor an option? Or just for some of the models?

    • Hi,

      The rose gold rotor comes only on the gold models, it is not an option.

    How would you compare this Co-Axial Calibre 8400 to the Co-Axial Calibre 9300?

    • Hi Justin,

      Well, I wouldn’t. Caliber 9300 is a chronograph movement and caliber 8400 is not. I would compare Caliber 8400 to caliber 8500, where 8400 has the anti-magnetic parts inside that were also used in the > 15,000 Gauss movement used for the Aqua Terra ‘Bee’ watch that Omega introduced last year.

      I would definitely think caliber 8400 (no date!) or any of the other new calibers with the > 15,000 gauss mechanisms and parts are the way forward. I guess the new 8500 caliber is referred to as 8500G (from the top of my head).

        Hello Robert,

        Thank you for your informative response. As an amateur watch enthusiast, your insight is greatly appreciated. I was looking to purchase my first Swiss time piece which would most likely be the Omega Speedmaster Co-Axial 9300. It seems as if Omega is looking to release movements > 15,000 Gauss on all their watches. Since this will be a major investment, would you recommend waiting for a new movement with increased anti magnetic components? Also I have been doing research but can’t seem to find the Gauss rating on the Speedmaster Co-Axial 9300. I would appreciate your advise regarding these two points. Thank you,

        • Hi Justin,

          Thanks for your kind words. Well, I wouldn’t mind owning a nice new type of movement with the protection > 15000 gauss, but I have done without for many years so I wouldn’t mind owning a normal 8500 or 9300 at this point either. The chronograph movements will probably be updated with the >15,000 gauss movement components in the next coming year(s). I wouldn’t wait for so long when I was in the market for a new watch right now.

          The Speedmaster caliber 9300 is – of course – anti-magnetic to a certain extent, due to its case construction. The > 15000 gauss models are anti-magnetic due to the use of special anti-magnetic components inside, a true innovative solution. The IWC Ingenieur, Rolex Milgauss and other models from other brands are only anti-magnetic due to the use of a weak iron core inside the watch case. Omega takes it a step (or two) further by modifying the movement itself.

          If you are in the market for a Speedmaster 9300, just go for it. Your watch isn’t subject to big magnetic fields during normal use I guess. I have never had issues with any of my watches regarding magnetic fields. Also not when close to a big speaker magnet or doing some induction cooking 🙂

    Any word on the cost of the new Seamaster 300? USD

    Just purchased the Seamaster from the Omega Boutique in Jacksonville Fl. today. My second Omega, other is the “James Bond” Seamaster. Leading me to this one is the anti-magnetic movement. Been very protective of the Bond watch regarding possible magnetic “war zones”. Hoping this one will resolve the issue as they claim and let it be a everyday watch if I choose to do so. I am excited that Omega brought back history with a beautiful new updated watch design. Really studied the simplistic lines of this watch. No date window, perfectly suits me and the merit of the watch. I prefer the stainless as well due to the weight. You have a watch on of quality on and being an amateur watch enthusiast, your insight would greatly appreciated. At first, was stand off “ish” about the hands but when you study the overall design look, then you come to appreciate and understand the achieving design. Thank you Omega for not putting the yellow/black 2nd sweeping hand. Had this been done, well……….
