Omega Seamaster Aqua Terra 15,000 Gauss Watch Review

Omega Seamaster Aqua Terra 15,000 Gauss Watch Review Wrist Time Reviews

It would be safe to surmise that Omega was the star of the Swatch Group last year in 2013. 2014 and beyond are looking pretty bright as well, but what we can safely say is that Omega has done a good job of recognizing and celebrating its past, while also firmly looking into the future. A watch like the Omega Seamaster Aqua Terra > 15,000 Gauss is really about both of those perspectives. In reviewing it, we find a solid classic Omega timepiece with a heart that literally dictates a guaranteed future of the brand. Let’s take a closer look at one of the most anti-magnetic mechanical watches around.

Also released last year in 2013, was the Omega Speedmaster Dark Side Of The Moon (reviewed here). I bring this piece up for two reasons. First, is that the popularity and hype of the Dark Side Of The Moon just narrowly edged out the 15,000 Gauss in regard to consumer and media attention. Omega was certainly aware that this was going to happen when they released them during the same year. The second reason I bring it up, is because even though ceramic (the case material of the Speedmaster Dark Side Of The Moon) is not magnetic, Omega did something totally different with the 15,000 Gauss in regard to tackling the issue of fending off magnetism.

Let’s back up a moment. Why all the fuss about magnetism? Well mechanical watch movements are traditionally made of mostly metal, most of which is ferrous metal. That means they are susceptible to magnetic fields–which are actually more prevalent than people think. Magnetism can do two things to a watch movement, and both are things you want to avoid. Magnetism can first act to completely screw up the accuracy of a movement because the balance wheel is being effected by the force, ruining its operation. This means that interaction with magnetic fields can make the accuracy of a mechanical movement all but useless. Second, magnetic fields can cause the metal in your watch to become magnetized. This will destroy your watch movement until a watchmaker can demagnetize it (if even possible in the situation). As you can see, avoiding magnetism when it comes to a mechanical watch is usually a good idea.

Normal mechanical watches are somewhat anti-magnetic, but not much. They can resist up to maybe 90 Gauss. Traditional anti-magnetic watches contain an iron shield around the movement to protect against magnetic fields. These protect up to about 1,000 Gauss, which is pretty good, but does prevent a watch that offers a view of the movement. It is unclear when or how most people would come into contact with stronger magnetic fields unless they worked around an MRI machine or in some type of aviation or industrial capacity, but it could happen. In any event, Omega sought out to beat all records by producing a watch movement capable of withstanding up to about 15,000 Gauss, and offering a display caseback to view the movement.

Such is the genesis of the Omega Seamaster Aqua Terra > 15,000 Gauss timepiece (yes, the “>” is part of the official name, but we will more or less call it the “15,000 Gauss” for short). The story, however, is deeper though than Omega  merely deciding to produce a single highly anti-magnetic watch to compete with a model like the Rolex Milgauss (that uses a more traditional anti-magnetic shielding technology). What the 15,000 Gauss represents is a major step in the evolution of Omega timepieces that will become a common part of the brand starting slowly in 2014, and progressing for the next several years.


Yes, what I mean is that the anti-magnetic movement technology employed in the Omega Seamaster Aqua Terra 15,000 Gauss watch will be deployed in all in-house made Omega movements by 2017 (the promised year by Omega). It will be a gradual roll out and the 15,000 Gauss timepieces exist as the first of a breed, and they celebrate what Omega has been dutifully working on for a few years now. What is the trick to their system? There is no magnetic shield or anything like that. The trick is that the movement simply isn’t magnetic, using non-metallic or non-ferrous metal parts.

    It’s a smart and sophisticated watch with a little dash of rebellion in the form of that stinger sweep second hand.  The dial is inky black and pin-striped, very classy.  It’s great to see a genuinely useful innovation that will improve time-keeping across the whole range of Omega watches, even if no watch can be completely anti-magnetic even using silicon parts.

  • Very nice. Nowhere near as cool as the dark Side of the Moon (the watch, not the album), but very nice nonetheless. 

    Part of me wants to say “I have no need for that much magnetic shielding”, and then the other half of me looks down at the mechanical chronograph I picked to wear today, and realizes I don’t need that either, I just really like it, and wanted it.

    “…a solid classic Omega timepiece with a heart that literally dictates a guaranteed future of the brand”.
    This “litterally” business, is it really necessary? The written English on this site is better than that, I feel. 
    Great watch, btw. I have only seen it in the flesh a few times and was happy to see that the yellow os much more subdued in reality than on photos.

  • Spaceguitar

    Part of me thinks when this movement is more commonplace down the road in Omegas that the stinger second hand will make this one pretty collectible. I’ve liked it from the start either way.
    A note on magnetism. I should do some reading, but if a computer monitor can have a built-in degaussing mechanism I wonder what it take to make & sell a device to degauss your timepieces at home. We spend money on winders, safes, etc., Not to mention the hoards of cash on the actual watches to begin with. To me, something to neutralize the fields would be a smart investment if you care about your collection. Of course Rolex and Omega wouldn’t be too thrilled…
    Anyone wanna go in on a kickstarter with me? LOL

  • Ulysses31

    Spaceguitar They’re less than $100 on eBay.  A slight spin on your idea… how about a watch winder with a built in coil that de-magnetises the watch as it turns?  I’m surprised it hasn’t already been done.

  • codpieceofjustice

    I prefer the styling of the Milgauss. However, unlike the Milgauss this watch shows the date, which for me is a must-have feature of any watch.

  • DG Cayse

    Spaceguitar Those items, both from Switzerland for approx. US$125.00 and from India for approx. US$70.00, are already available.
    From the specs of these items, I think it may be able to be manufactured for significantly less. 
    And the ‘degaussing/demangnification’ procedure is accomplished in mere seconds.

  • timekeeper703

    Love this watch………….but the vintage side of me wishes this was branded under the RailMaster collection, like the
    original, since the focus is it being anti-magnetic.

  • spiceballs

    Grinnie Jax – – – and maybe Rolex can update to a “Dora The Explorer III” version?

  • spiceballs

    Want to like these but they do NOT sit comfortably on my wrist.

  • Grinnie Jax

    spiceballs But isn’t it the way it was intended?

  • stefanv

    DG Cayse Spaceguitar  I made my own degausser from a $20 Radio Shack transformer and a momentary pushbutton switch. Do you remember those cassette tape erasers? Those make perfectly good degaussers if you still have one laying around. Hold the watch in one hand and the eraser in the other. Spread your arms, turn on the eraser, bring the watch near it and wave it around a bit, spread your arms again, and turn off the eraser.

  • OmniRak

    The thing I like is not necessarily this version of the Aqua Terra in and of itself, but more the idea that it is only the first of Omega’s line of watches which will be so anti-magnetic   While it’s pretty easy to avoid magnetizing a watch in the first place, the idea of such movements becoming standard across all of a brands watch offings is great.  I look forward to their growth in this arena and I am definitely temped by their new anti-magnetic De Ville Trésor

  • Spaceguitar

    Ulysses31 Spaceguitar This is what I get for posting first, then googling later!
    But yes, I love your idea. That is actually quite cool.

  • hautejalapeno

    I previously thought of Omega as an also ran, that changed when I saw this watch in the flesh along with the Dark side of the moon. These 2 watches have reinvigorated the brand and brought in new admirers (me included). The brand has built upon the success of these 2 watches with a very strong showing at Baselword. Keep it up omega, and also please release a SS tresor…i’d be all over that!

  • spiceballs  a common occurence with Omega unfortunately

  • I really like the Aqua Terra line. I also really like this bumblebee offering, but I’m bugged (hehe) about the seconds hand, in that my eye ALWAY falls on it. Seriously I will try to look at the time and I have to focus on the hour/minute hand after my eye adjusts to the seconds hand. 

    I see it more as a collectible watch and less as a daily wearer–which is a pity since Aqua Terra’s have “daily wearer” written all over them.
