This is a complete replica of the Galaxy Gear. Build quality is excellent, looks like they use all the same screen, shell and band (with camera) of the original GG. Sealed non-replacable battery in a relatively thin body (about 11mm, same as GG1).

It uses MTK6572, has 4G ROM (about 1.1G usable), 512MB RAM. Pity there is no microSD slot to expand the memory.

It has only one button (to switch on watch / wake screen, and be the Home button). To navigate, swipe down from top = back, swipe up from bottom = menu.

There is a true Android 4.2.2 device and not some cheapo phonewatch with Java apps. There is access to Developer's options and USB Debugging (mine was set "on" already). This allows use of ADB to install apks.

No there is no Google Play store, no built-in web browser or video player. I am sure you can install these apps manually (I dunno how to install the Google Play package and I dont intend to do that).

Yes there is wifi, bluetooth (connects to my BT keyboard and working) and GPS (not tested).

I have not really tried out the apps, but they are pretty standard ones. I have also not tested the connection manager to the phone.

What I have done is so far are:

(1) Root the watch - after many failures using MTK Droid Tools, Framaroot, eroot etc., a friend gave me a tip about this chinese root tool called Kingroot. It is very successful in rooting most if not all chinese phones particularly those using Mediatek chips.

It installs its own version of superuser called kinguser, and its own version of su binaries. I thought what the heck lets give it a try, and it rooted the watch on the first run, and has no problem since.

Kingroot download page (Google translate) - choose "Kingroot PC ..." version

The program is in chinese. Installation was full of funky unreadable characters but most of the responses eg yes / no are the highlighted buttons. After installation, there is only one button to press. Just like all other one-click root programs, enable USB debugging on the watch, plug into USB cable and click the button, and it will do it all for you. Your watch should have rebooted when the process finishes.

(2) Back up the firmware using MTK Droid Tools + SP Flash tools - I followed this guide:

CONCLUSION:

This is a great find!! Excellent build quality, lightyears ahead of ZGPAX and SmartQ ZWatch. The hardware is similar to the Omate Truesmart / InWatch Z, except it is 4G ROM / 512 RAM with about 1.1Gb internal memory usable. I can live with this for the price of < USD 100.

You should go and buy this watch now because it is going to sell like hot potatoes. I am not going to test all the apps or answer questions about them, because they should work the same as Omate TS.

I am NOT a developer so dont ask me to do this and that cuz I dont know how to. I only back up the firmware in case I screw the watch up.

Hope that someone more knowledgeable would buy this watch to tweak and develop it. Then you can ask him questions.
