No.1 D5 – Everything that You Ever Need in a Smartwatch!

Many tantalizing Smartwatches were introduced this year. But all of them lacked something. This included an independent watch, heart sensor, pedometer, 3G, etc. So looking at this, the renowned Chinese company ‘NO.1.’ launched their newest smart watch called No.1 D5.

You guys would be glad to know that it is slim as compared to the majority of the smart watches. The part of this watch is that it is IP65 certified.

Hardware and OS:

The heart of the D5 smart watch is the solid 64 bit, Octa-core MediaTek MTK6572  processor with 512 MB of RAM which is enough to handle a low energy consuming watch. The internal storage is 4 GB with no option of inserting a TF card, which is the only drawback of this watch.

Moreover, the smart watch is powered by a Li-ion battery having a capacity of 450 mAh and can be charged through a USB charger. Sadly, this watch does not support adsorption or magnetic charge. This time, NO.1 D5 has a built in OS. The OS is based on Android KitKat (V 4.4), and the best thing is that now it supports google play store.

But for them, this is the first smart watch which not only has a SIM slot but also supports 3G network. But wait, friends! That is not all this watch offers. Apart from networking, this watch is the first of its kind to have a built-in WiFi 802.11 AC and Bluetooth 4.0 (supports both 2.1 and 4.0).

  1. I got a price from them…it will be launched from 20th December and will have a 124 USD price tag. Not bad I guess!

  2. I just ordered the watch from Geekbuying and when I inquired about the SIM slot, they indicated that they did not find one after taking the watch apart. Furthermore, the watch comes in only two colors: Silver and black (not the gold often illustrated). I guess the truth will be known when I receive the smartwatch.

    1. Thanks for reading. When you receive the watch, please let me know whether it has a SIM slot or not. As far as the color is concerned, you’re right that it comes in two colors. However the article is written before the release of the watch, the illustrated pics are just to show the multiple clocks not the color. Tell us whether you like the watch or not.

    2. Hello,

      iam thinking about buying it too…
      did you receive your watch and can you confirm if it has a SIM slot?
      Thanks in advance

      Greetings Marc

  3. Compared to some of the other smartwatch especially I have tried, I really like the look aND feel of this one. Just wondered if anyone knows what apps function best on this, wear apps don’t work well, if at all. Any suggestions?

  4. Gearbest claims this watch has a GPS, though there’s no mention of it here. If this is the case can gpx track logs be saved? I’d be grateful if anyone knows.
    Also I read that this watch does not show notifications from your phone. 🙁

    1. I have one. I does have GPS and it does show all notifications from your phone from any app that you like. I have it connected perfectly with my LG G4.

  5. Im thinking of buying one of these.Anyone know if its ok with android 5.1.1 on a samsung galaxy s6 (new) and 4g network ?
    I bought a u18 and it doesnt work with my phone, not sure whats up because it was meant to be compatable!

    1. You can’t change the app as the antenna for the phone capability of it is built into the strap.

    1. Yes… it will connect to your S5 trought bluetooth using a app you install on the phone that let you make calls, send messages and receive notifications.

  6. Hello there,
    I own the watch and can confirm it is good value for money, very nice gadget. However, have two major difficulties. First is related to health sensors comms with smartphone applications – could not find any appication that will connect to watch, neither will any application work correctly if installed to the watch directly. Could you please suggest the app to use? The second one is related to data comms via SIM card – watch works fine as a phone, but cannot access data from mobile network (in Croatia). Thanks and best regards. Miodrag

    1. Since it has the Google Play store, you could try installing Google Fit or Samsung S-Health. both can track and log steps. Personally I prefer Google Fit on my smartphone, since my information is also accessible from web browser.

      1. Thanks for answer Vernon – have tried both (and some others too), but doesn’t seem to work. At No1 facebook page they rcommend using mediatek smartdevice apk (as a bluetooth connection software / watch helper), which alegedlly works fine with Google Fit. Unfortunately mediatek smartdevice would not work with my d5 🙁 Only watch helper apk that works is the one provided with the watch itself. That apk establishes good and reliable bluethoot link, but gives no support to any common health / activity tracker software. Still searching for apk that will work…

  7. Hello,
    Where I can buy the original watch strap with built-in antennas and what is the cost?

  8. Doesn’t work with Tmobile….just an fyi….definitely having buyers remorse. Couldnt even make calls

  9. Can someone confirm if this watch can receive notifications from the phone. That’s the only purpose of me buying this. Do not plan to install a sim card in the watch.

      1. Postovani g. Sajina,
        Ne mogu nikako naci aplikaciju tipa endomondo koja bi koristila senzore sata i radila samostalno na satu bez potrebe kontinuirane konekcije s telefonom. Isto tako, sat mi ne omogucava podatkovni promet preko SIM kartice. Kakva su vasa iskustva, imate li kakav dobar savjet? Lijepi pozdrav.

  10. Can i install whatsapp in this? Or a maximum of how many apps?

    If i buy this from Ali express or Gear Best…will i get to return this and get my money back?

    If connected to bluetooth can i send texts right through the watch using google?

    Please answer me..It will be a great help.????

    1. yes, it can install whatsapp, d5 512mb ram, so it deponds on what app you install. you can buy from gearbest.

  11. I just bought the watch. Everything is good, there’s a nano sim slot that connects to 3g but i can’t receive calls from my watch using bluetooth. Anyone facing the same issue? Any other apps to use beside watch helper? I have another watch G3 using fundo apps
    which i can make and receive calls using bluetooth.

      1. Yeah, I did that and able to receive push notification but not making bluetooth calls using watch helper app. Anyone able to make bluetooth call from G5 let me know. Thanks.

  12. Hi, i want to ask:

    I bought one at 96 dollars, product called: NO.1 D5 Android 4.4 Smart.
    after 1 day I cancled it because i saw another seller have the same model just with Upgrading:
    android 5.1 (not 4.2), Ram 1 gb (not 0.5gb), Rom 8 GB (not 4gb) and quad core 1.3Ghz .

    1. FIRST VERSION: http://www.everbuying.net/product1128292.html
    2. I THINK THAT’S NEW ONE: http://www.ebay.com/itm/331952220199?euid=9ae72eeb3ac84bb2a066ec7a93dea119&bu=44249362542&cp=1&sojTags=bu=bu

    Is somebody know if this Smart watch in this model (NO.1 D5) is exaclly one just with that’s upgrading?

    thanks 😉

  13. I receive my NO.1 D5 3 days ago and have problems with bluetooth connection with my Xiaomi MI4i.
    The connection its lost every time and dont reconnect automatically never.

    Can I make calls with bluettoh connection? I try everything but cant find this option.. just with a SIM Card.

  14. it is impossible to make/answer calls and then speak directly through the No.1 D5 (when it is connectecd and sync via bluetooh with a smartphone), can you confirm that you use the No.1 D5 as a phone (listen and talk) with no SIM, but just via bluetooth?

  15. Dear Sir, I have bought a smartwatch No1 D5 from “aliexpress” site. I have found that my smartwatch can not connect with the camera of my smartphone and additionally there is no icon of camera in my smartwatch. After stating my problem to the seller, he respond to me saying that “my smartwatch doesn’t support remote camera”. In your site, I found that D5 does support remote camera.
    Please inform me if it real supports remote camera and how it works!!!!!
    Additional can you inform me if I can change the wristband of my D5?

    Thank you in advance for your information.
    Best regards

  16. Dear Sir,
    I am still waiting for your reply, concerning my questions 18 days ago.

    Best regards
