Omega Nekton and Case Thickness

I may not exactly be qualified to make this claim, since I wear a 300m that's even thicker than those, the GSAR, but I felt like the SMP300m wore its thickness quite well. It didn't really feel like close to 14mm. To be honest, the planet ocean at 16mm thick felt more like 14mm to me, and the SMP300m felt more like 12.5mm to 13mm.

At the very least, I'd suggest trying one on before disqualifying it due to thickness if you truly do like the watch.

I agree, my 300M wears thinner than it's case would suggest due to some very good case design / architecture by Omega. I would however prefer it to be a bit thinner, and with this the weight would come down a bit, I do feel it is a bit weighty / top heavy.

I have this watch on a smaller wrist than yours and I feel it wears quite well for it size. Perfect example of a watch where you cannot trust the measurements alone. I imagine the thickness is from the crystal. Hands down my favorite SMP300

I don’t care about the thickness but they need to something about that horrible helium escape valve, there are plenty of examples of divers that have a escape valve but its far less intrusive to the design

I agree, but it is part of the watch's identity and I doubt they will ever change it. Be good if they did though. Imagine it! Also, we don't need the He valve, not even serious divers do, only a tiny percentage of professional divers ever need them and I guarantee a tiny percentage of them, if any, use a 300M 😂

It’s a signature feature of the model. Instantly recognizable.

The fact is that even the less intrusive designs are basically pointless, because essentially nobody is a saturation diver breathing mixed gasses in a pressurized chamber.

But like you said, there are other choices. Maybe choose a Pelagos 👍

I would disagree with that take their are many vintage seamaster 300s that don’t have a helium escape valve. Also I know we don’t need an helium escape valve which is part of my point, it is so extra and in this specific case taking away from the design of the watch

Such a shame the older design language >>>>> than the new one.

If you don’t like the HEV try the 300 heritage. There’s a Seamaster for everybody.

Yes but part of the 300M's identity is it's helium escape valve, it was introduced with it from it's conception in 1993. You may disagree, but it is not really subjective and you are therefore wrong 😮

I have deal breaking features for watches too. It just steers me away from them because I don’t like the watch if it has that. Just the way it goes.

I don't have a great problem with it, but do think the 300M design would look better without it.

Not sure I've ever heard a commercial diver or a recreational diver for that matter complain about the Omega Seamaster being too thick. How deep does the average desk go?

You want a thinner, better proportioned Omega Nekton possibly without the He escape valve. 🤔 I think it does exist.. It's called a Rolex Yacht-Master. 😉😂

Good call! My friend has this model, it is nice. I have always liked the slightly more sporty blue dial one, both great 👌

I suggest that you send a strongly-worded e-mail to Omega headquarters, demanding them to make a thinner version of the Nekton, just for you.

Helson makes a 500m rated watch that's 12mm thick and Blancpain makes a 300m rated watch that's 10.8 mil. Heck, Longines makes a 300m rated watch that's under 12 so Swatch Group obviously has that power.

Agree, my Big Eye is fine at 14.50 mm doesn't bother me, although it would be nicer if it was 13.50. And to completely agree with you, my speedy is 14 mm and is probably perfect at that thickness. But part of horological history has involved refining watches to have good specs but with slimmed cases or at least not ridiculously thick cases. It is just my personal opinion that the 300M would be more enjoyable if it was thinner and therefore slightly lighter.

One word…2254 ;)

I think it is exactly our place to tell watch makers what we expect from them.

13.7mm is nothing compared to my SeaStar, but then again it’s 600m. I’ve got a Spinnaker Spence that’s 300m and only 10.9mm thick (no date)

Looks like I’m in the minority here but I literally sold my Omega Aqua Terra 41 because it was too thick 🤷‍♂️

I've got a 300m dive watch, a Zelos Mako V3 Titanium. It's 11.5mm thick including the crystal. It has a date too, but the way.

Under 15mm is acceptable ☺️

I said "I am not the one" you can be if you wish. Enjoy the hobby..

I’ve had my pair for a couple of years now. I like the Nekton, but already have a black. Love the watches, permanent keepers.

Makes total sense--and your point about refining watches to have slimmer cases is interesting, too, especially with chronos. I find it counterintuitive that the first automatic chronographs issued in 1969 were actually thinner than their modern counterparts despite all of the advancements in movement technology, manufacturing techniques, and drastically increased prices over the past 50 years. There's no reason that we can't get an automatic chronograph under 13mm without having to spend over $10k on a Zenith or Rolex. I mean, there IS a reason, but I'm not factoring greed into the conversation ;)

I don’t mind the thickness as the case diameter and overall presence work. I wish they would revert back to the no wave case size. 41x48x13.5 would be perfect for that watch.

You’re good my friend. I have this (also grade 5 titanium bezel like the Nekton) and wear thinner than what it says. I think you’ll really enjoy it.

Omega should make the seamster in a desk diver version. cut down the water resistance, remove the helium escape valve, 40 mm case, 11-12 thickness, on the fly adjust. done sir done new classic
