Hands-On: Omega Seamaster Aqua Terra 150M Worldtimer in Sedna Gold Possibly the boldest GMT Worldtimer out there by Balazs FerencziDecember 19, 2019 MIN READHands-On: Omega Seamaster Aqua Terra 150M Worldtimer in Sedna Gold
Let’s see if the new Seamaster Aqua Terra 150M Worldtimer in Sedna Gold is something I can cosign.
I’m not particularly a fan of gold watches. Unless they are white gold, that is. I have nothing against the alloy or anyone who wears a timepiece made of gold. I like the tone of rose gold, even yellow gold, and I also have some gold (plated) vintage watches. Mind you, I bought them for the importance of their movements or the model (like this Omega Moonphase Jumbo), not for their case color. Now white gold or platinum is a different story. Granted, they look like steel, and I guess this is why I like them. I think that gold does not go well with my skin tone. Or so I thought. Until I was offered to review the new Omega Seamaster Aqua Terra 150M Worldtimer in steel…or Sedna Gold. I knew what my Fratelli would say, so I went with the gold. The thing is, I don’t want to give it back now.
Steel…or Sedna Gold. I knew what my Fratelli would say, so I went with the gold.
Aqua Terra 150M Worldtimer
The Omega Seamaster Aqua Terra 150M Worldtimer is not a new model. It’s been out for years now being one of the most successful watches in the Aqua Terra collection. This year, Omega is adding several timepieces to the family. One of such additions is the topic of today’s watch review. We are talking about, and now bracelet yourselves for the name, the Omega Seamaster Aqua Terra 150M GMT Worldtimer Co-Axial Master Chronometer 43mm in Sedna gold. This specific watch sits on top of the Worldtimer family. It does not only have a solid gold case but a matching bracelet, too, making it a pretty substantial watch.
Nevertheless, the gold case is not the only remarkable feature of the Aqua Terra 150M Worldtimer. Its dial is just as exquisite and beautifully crafted. And then we have not even talked about the movement.
The Aqua Terra 150M Worldtimer is a big watch, both literary and figuratively speaking. The size is 43mm, the thickness is almost 15mm (14,8mm to be precise). What is more interesting, however, is the 242g weight. Inevitably, this involves heavy parts like the dial or the movement. Yet, this – kind of – gives you an idea of what heft are we dealing with here. Cleary, the watch does not remain unrecognized when worn.
On the other hand, one can get used to this bulk of gold quickly. If we look at the finishing, we find no blemish whatsoever. The Aqua Terra 150M Worldtimer is just as nicely executed as any other Omega. Polished and brushed surfaces complement each other. The bezel, the bevel on the lugs, and the middle bracelet links are polished. The watch’s sides, the top of the lugs, and the bracelet side links are brushed.
The case back is also mostly brushed. Though, there isn’t much of a gold surface there. The center of the back is a huge display window. I don’t mind this, the Omega caliber 8939 is a thing of beauty, and I’m happy to look at it. One thing worth mentioning is the fact that the watch is resistant to magnetic fields up to 15,000 Gauss. All this, with a display case back. We’ve come a long way since the early days of antimagnetic watches, ladies and gentlemen. On the case back, you see the model name and the water resistance rating.
Furthermore, the usual gold hallmarks and other designations on the underside of the lugs. Clean and simple. The large screw-down crown’s surface is also a mix of polished and brushed parts with a modern-style Omega logo in the middle.
We will talk about the caliber 8939; I promise, but first, let’s stop for a second and take a closer look at the dial. A lot is going on here too. We have three parts in two layers. The outer dial is opaline silver with vertical teak stripes with a circle of global destinations in red, blue, and sedan gold. Note that right of London marked in red (GMT), you can see Bienne, the hometown of Omega. The center of the dial has a 24-hour Hesalite crystal ring where the lighter part indicates daytime and the darker nighttime. It sits a bit lower than the rest of the dial. Finally, we arrived at the Aqua Terra 150M Worldtimer’s center. Here, we see the vision of Earth as one would look down over the North Pole. This part is grade 5 titanium, laser-ablated to create the blue ocean.
The date aperture is at 6 o’clock, just above London. The hour indexes are long triangle applied indices with Super-LumiNova paint on the top of them. The gold arrow hands also have the luminescent coating. The brand name is below the 12 on the outer dial, while the model name, Seamaster, is etched into the Earth plate. Domed scratch-resistant sapphire crystal protects the dial. It has an anti-reflective coating on both sides. Overall the watch is easy to read since the hands and the back of the dial are contrasting. Indeed, a lot is happening on it, but it does not become disturbing for a second.
Omega Caliber 8939
Finally, we get to the Aqua Terra 150M Worldtimer movement, the Omega caliber 8939. We are talking about a self-winding, mechanical movement with Co-Axial escapement. The 8939 has 39 jewels and a frequency of 25,200vph. The power reserve is 60 hours.
Furthermore, the caliber 8939 is a Master Chronometer, certified by METAS. We have talked about the magnetic field resistance above. You can find a free-sprung balance with silicon balance spring inside. Beautiful Geneva waves in arabesque finishing make it more pleasing to the eye. Not to mention the 18-carat Sedna gold rotor and balance bridge that we can see through the display back. As you’d have it with every new Omega, there is a 5-year warranty that comes with the watch. Although this is not the latest news, it’s still worth mentioning from time to time.
Gold on gold
The steel version of the Aqua Terra 150M Worldtimer comes on a bracelet or a rubber strap. The gold version comes either on a leather strap or a gold bracelet. I thought that if we go gold, we should go all in, and I must say if you ever have the money and urge to buy this watch, please only by it on the bracelet. It just works so well with the rest of the Aqua Terra 150M Worldtimer. The bracelet is thick but not too bulky; the mix of polished and brushed links gives the piece a nice contrast. The double folding clasp has two safety push-buttons. It is tight and secures well. You do not have a micro adjuster on the claps, but with these types of bracelets, it’s a given. The watch head is massive, so you need a bulky bracelet to balance that out anyways.
The Aqua Terra 150M Worldtimer will be available in stores starting December 2019. If you would like to get it on the leather strap, the price tag will come to €21,200. If, however, after reading this article, you think that the gold on gold is your thing, you’d have to leave €33,800 at the retailer. The steel on the rubber is €8,300, and the steel on steel is only €200 more. Yet, the Aqua Terra 150M Worldtimer is more than a price tag. Surely, if you see a brand-new solid gold watch from a top brand, you expect a hefty price tag. What I would like to emphasize, though, is how beautiful this timepiece is. How well the gold case and bracelet work with the colors of the dial along with the Omega 8939 movement, that the top of the line from Omega.
