I've been super intrigued by Glycine since I learned about their relevance in the Vietnam War, i.e. that the Airman model was apparently very popular among combat pilots.
However, what has kept me from buying one yet is this little fact:
Now, I'm not hating on Invicta. I actually think that they have a few decent models that are actually pretty good "bang for the buck". I even own a Pro Diver...
However, Invicta is also this...
I know, I know... This shouldn't keep me from embracing Glycine in the same way I embrace Omega (which is owned by Swatch, who had their fair share of ugly watches... Although probably not nearly as hideous as the atrocities "created" by Invicta).
But I can't help but think that subconsciously this may be the reason I never pulled the trigger on a Glycine.
Apart from all that, I think that Glycine is a super interesting Swiss brand with an apparently rich history and attractive models (they have a pilot watch series with strong IWC pilot vibes that I like a lot...). The Combat Sub is a pretty cool watch too and from the positive feedback I've read on gen forums, I also have the impression that they must be pretty good value for the money.
