Well, you've got only one choice from the big OEMs...is the Gear S. Otherwise, there's the AI Watch which is expected to release soon. I say soon because they have delayed the launch a few times. But take a look:
www.aiwatchtech.com
Otherwise there are quite a few SZ (Chinese) watch's out there. Be careful, many of them are junk. I would stay away from the TS, there is NO developers supporting it at all.... and neither is Omate for that matter.
Not that I disagree with the above assessment, but I have now a used 1G/8G extreme version/US TS and I am pretty happy with it.
It is the only one I know of (including the Chinese copies out there) that offer it all: reasonable size with 3G/Wifi/bluetooth/gps AND full android, which I really like.Battery life is actually a bit better than expected (mine came with one of the ensec roms): I get easily 1 day.
I also own a Gear 2 (3 days of battery life; everything works well and less weight), which is a great little watch, but I hate being dependent on the companion phone (and even worse, it has to be one of the more recent Samsung ones: one reason why I never switched to iPhone/Apple).
Now, with the Omate TS you get something that works probably 95% of the time. If anything brakes, you are on your own though....no customer service, no replacement parts....so it all depends whether you are willing to take that risk....
On the positive side there is a lot to explore with the TS. I just installed Big Launcher (10$ on google play) and it works great (so far). Many apps that surprisingly work well on it. The freedom to get apps running from the Google Play store was one of my biggest incentives to try this little beast.
So far so good
Good luck!
PS: I am not 100% sure why Omate dropped development of this watch. They are now starting to advertise the Omate X, good looking, but not much different from all the many, many others out there (from companies with much bigger/well known names)....I would have sticked with the TS design idea and come out with a TS V2 (and continue to support TS V1 to not lose all the V1 customers!)....but that did not happen unfortunately....so this TS is my toy until one of the well reputed companies deliver something equivalent....(and not force you to their very confined infrastructure like Apple or Samsung)
