Karl here with a new review. This one is a little different. A smart watch, but not your average smart watch, as most smartwatches supplement a phone. This is a standalone smartwatch. It runs full Android 5.1. It is the D6 by No. 1. It has a 3G radio and SIM card slot. I was really excited when I found out I could do this review.
Below are some pics from their website.

First Impressions
The watch looks good to me. I had a few people say it looked big to them but I don’t feel like it is too big….in fact I wish it were bigger. Below are some pics I took. My pictures don’t due it justice so that is why I posted the professional pics above.

First Tests
First thing I did was try to push it to the max and do some absurd testing. What does that entail? For me it was watching movies on a watch. Kodi Netflix MX player, Plex, HdHomerun, and Emby.

To my surprise most worked pretty well considering it is a watch. With Emby I couldn’t use the built in player and had it use MX player and I couldn’t get Plex to work at all. This is not a deal breaker…it is really a ridiculous test but sometimes you do things just to see if they could be done. I also ran Antutu and got a 23221 on version 6.1.4….not too shabby for a watch.
OTA Firmware Update
After a couple days I received notification that the watch needed to be updated. So I performed the updated and followed the instructions. It went through and when it booted the first time after the update it hung on the boot animation and got really warm. I waited a long time I took the battery out and when I turned it on next it booted properly. Then a 2nd update appeared but this time the watch soft bricked. I went to the website, downloaded the latest firmware, and installed it. It mostly went off without a hitch except I should have waited to plug in the watch until after I installed the drivers. It took 30 tries for me to catch the device in the device manager to install the drivers manually from the download. Included in the download were the drivers and flashing tool and img. It did not come with any instructions that I saw but it was easy to reflash. (Received another update today and it installed perfectly.)
Setup
I didn’t like the built in launcher at first so I installed Nova Launcher. Added 3 widgets one is clock, circle battery widget from the play store, and power control widget. Nova is pretty customizable so I was able to mimic an android phone setup. But I ended up getting errors with Nova and it would force close frequently and I had to choose default launcher over again.

I really wish Nova worked better, didn’t close like this, and I think it takes a toll on the battery. I installed Apex launcher which worked pretty well and not too heavy but had to sacrifice too much. After a while I ended up back with the stock launcher. It’s good enough for a watch that runs full android with a small screen.
Use
So as I see it, there are a couple ways use the device. You can use it as a standalone. Pop a SIM card in and use it as your phone. A Bluetooth headset is necessary for this. Speaker phone is weak and there is no privacy. I tested first with a Ting SIM card. Popped it in and I was immediately up and running. I only made a few calls this way. I also tested with a Metro PCS SIM. Not quite as easy…I had to call and give Metro my IMEI number, and about 30 minutes later I was in business. I am not a fan of Bluetooth headsets so I didn’t enjoy this way. And I got caught at the end of the day once before I started charging midday without phone service. 2nd way is you can use it paired to your phone through Bluetooth and receive notifications, pass files to the watch and uninstall applications on the watch. Use it like a traditional smart watch. I didn’t find this particularly useful and when you get out of range of the watch both the watch and the phone beep. I opted to use it standalone. When out and about I turn on my hotspot on my phone and when home I use my home WiFi. This seemed to work best for me. You could also pair the phone and watch and also use hotspot. I just didn’t find notifications particularly useful. The good thing about this watch is you get many choices.
Battery
The battery has a 450 mAh capacity…which is tiny considering this processor is installed in full size phones. I really had to watch what I installed and had to be conscious of background tasks or it would destroy the battery. After testing to see if I could make it all day I started charging on my lunch break at work after that I didn’t have to be concerned with battery life. It charges relatively fast. After receiving the last OTA update when this review was nearly complete, I got significantly better battery life. I used it quite a bit the next day and I had about 20% left at the end of my work day with no charging. Depending on how it is used will significantly impact battery. I would recommend a second charging cable. It is proprietary with magnets that aren’t particularly strong. I found sometimes it was difficult to get it to stay.
Apps
I installed lots of different apps. Everything would install and was mostly usable. On a small screen it was sometimes difficult to navigate. I covered all the video apps already but I also installed ES File Explorer and to get on the pop bandwagon I installed Pokemon Go and it played fine.
There are thousands of apps and if you would like for me to test one leave a comment below and I will give it a shot. I live in the United States so some apps might not be available.
Radios/Antennas
Cellular, WiFi, or GPS worked ok. I had more dropped calls than I typically did with my smartphone. I do live in rural America so this will vary. WiFi range was OK. With Pokemon Go I did notice that trees were enough to disrupt the GPS signal.
Final Thoughts
It’s a pretty neat watch considering what it is doing in such a small amount of space. With this last update from No.1 battery life improved a lot. I wish it had come earlier in the review. It is definitely up the tech junkies alley and would make a cool gift. I am sure there are a lot of uses that it could be used for. There is a long thread on XDA as well covering the watch and I would imagine a custom ROM will be out soon. People are already flashing an img from another smartwatch on this one. Supposedly 6.0 will be coming to the watch in the near future and hopefully bring adaptable storage to the watch. If you have any questions feel free to post in the comments below.
I would like to thank Chinavasion for sending the NO. 1 D6 to review. It comes in 3 different versions: silver like shown in review, gold, and black. You can purchase it for $76.99 on their website. Alternatively, you can also find the watch on GearBest, GeekBuying, eBay, and Aliexpress for similar or slightly higher prices up to $90.
