Chinese Pebble Clone

So I discovered a manufacturer in China that has started manufacturing a smart-watch that is plainly put a clone of the pebble. I just received today my production sample and am testing it. It's based on the EFM32 Cortex-M micro-controller. Bluetooth 4.0 BLE. The screen is Sharp Memory LCD. Battery 270 mAh , they claim battery life is over 10 days. Firmware is based on FreeRTOS and looks very similar to that on the Pebble. Watch has the same 4 buttons layout and the exact magnetic charger. Water resistance is rated IP 67. Tested it by tacking a bath. Even has the same issue with an easily scratch-able screen . Comes with 4 watch faces.
Here are some images :

These things go for 58 usd a piece. They haven't hit any sites like DealExtreme or Aliexpress yet.
This is the Android app used to connect to the watch if anyone wants to decompile it : https://docs.google.com/file/d/0B_0tZLvAcbvCYVVSaEQzVWpsZzQ/edit
Managed to find out that ZTE is selling this device under their brand : http://www.appchina.com/app/com.mtt.smartwatch/
It's exactly the same as this ZTE as I am curently using the ZTE app to connect to the watch.

the ZTE bluewatch looks a hell of a lot better?

This is basically the ZTE bluewatch in a different case.

Guess you'll need about 9 days to test the battery

It came with a half charged battery and it ran out of charge after 5 days.

Super anything else you've found out? Any other issues?
would you recommend it? :good:

Pretty hard not to recommend for 58 bucks. I found that on my Note 2 it sometimes looses Bluetooth connection after a few hours but doesn't seem to have this issue on the P6. The companion app for Android is just version 1.0 and has just been released last month so I am hopping there will be updates to solve this.

Manufacturer sent me an updated companion app that seems to have fixed the connection issues. https://docs.google.com/file/d/0B_0tZLvAcbvCR1pZcWw0OHdxcWQxQUt2bUFJczNRSXdtV3A0/edit
They claim to provide updates at least once a month.

Good news. :laugh:
can you use apps from the pebble apps store?
does this work as a stand alone watch? I.e. when its not connected to a device.

No you can't use the Pebble app's and yes it does work like a standalone watch , you can even completely shut down Bluetooth. Till now I'm quite impressed with the little guy. I'm now used to being able to see all my notifications on it and to control the music player. Pedometer is also kinda cool and the data syncs to the phone app.

same spec as the pebble

So without connected to a device you the the time, date, does the vibrating alarm work, any others functions?
Are the spec's exactly the same as the pebble with all the sensors and GPS?
The 10 day battery life is just fantastic. :good:
Thanks for the info' :good:

i'm writing right now a detailed review of the watch and will be posting it in a new thread.
Yes it has all the functions you would expect from a normal watch and they can be used without a phone , so you can set alarms.
Neither this nor the Pebble have GPS. But they do have an accelerometer.

The info' in the ClearDroid link watch comparison I posted is incorrect, its says it has a GPS.

Magnetic and it doesn't have that. The review is up.

I have to test this for a longer time before I can answer on that. I have had it turned off between my test so far, so I don't have a clear picture yet of it. Will update my post when I know more.

The version I test here is only for Android. MIMI are saying they are working on a version for iPhone, but they can't say when it is ready. They are aiming for December. The cost is right now unknown, but I believe it will be around the same as this version.

Sorry I missed it but what is the cost of this current version?

On the IP67 test. The International Electrotechnical Commission requirements are 30min/1m. The IEC is the organization that makes the standards for the test/rating, so if it does not meet 30min/1m static immersion test then it can't technically be IP67. Just a heads up.
Thanks for reviewing it.

okay thanks for the info, but here http://aceeca.com/handhelds/ip67 it says
6 Totally protected against dust
7 Protected against the effect of immersion between 15cm and 1m
And if that's the case, it does fill the requirements. As it is water & dust-proof. Can be soaked more than 3 hours in 50cm deep water according to MIMI.

Max 3 days it seems.

looks nice, but also rather huge
and very disappointing to see the exact same crappy companion app
that came with the u8 and all those other clones
i assume you have to have either phone or media audio connected for the watch to work at all?

IEC 60529 (doesn't get any more official than this)
The link you posted is technically incorrect as the lowest point has to be at a depth of 1m. If the object is more than 850cm (can't remember exactly but it's in the pdf) tall then it requires 15cm from the top of the device to the surface of the water.

Clockfaces
Hello,
I just bought this smartwatch and waiting for delivery. Do you know if there will be more clockfaces ?
Btw, 3 days battery sounds good enough for me.

I have this watch almost two weeks now, very nice watch and the design look quality. The things that i notice is that, connection sometime disconnect and you need to connect it by your smartphone not like other models that the watch it self searching for the phone. Heartrate seems accurate. The liveview cam is laggy and not full screen. I hope they implement auto face detection most pics taken is blurry. Qwerty keyboard not a default handwriting is awful very slow. Sometime the watch is autorestarting so you need to pair it again thru you smarphone and open the apps. I hope they could update thebfirmware soon.

Also how to change alert tones, when entering engineering mode theres a lot of tones to choose but cannot change or use it.

Battery is ok for a couple of days, BT connection is stable for me, but also depends on what phone you use and how strong the BT is on the phone. No idea about Lollipop, but I think it would work.

I have a OnePlus One, I owned rwatch m26, the app worked well with kitkat while with lollipop I had to use an alternative apk, SmartWear. Since you bought it there were updates? I found a blog that talks about a new firmware with the voice command, but the site mimi-hk says nothing. However, I think I'll buy, the transreflective display, the ability to watch the time or answer the call with the shake and ip67 are rare on this type of device. On Lightinthebox it's 89 euros + 13 for shipping, I think it's a good price. Thanks for your suggest

Although it's not released yet, the New InWatch Z (the old/current one is 2G) is a 3G standalone, Android & always on. Check out the thread it should be released in a few months. But! ... its one of the most expensive one.
User S7yler reviewed a cheaper always-on watch on his Utube channel, but i can't recall if it was a stand-alone.
If you do find one please share it with the XDA smartwatch community
EDIT:
https://www.youtube.com/watch?v=mcKetu-JIws - its not a standalone

There will always be a balance between battery life and utility. Android (Kitkat and greater especially) offers a lot of use natively, and as far as I know, there isn't a single phone with the system that suggests keeping the screen on all the time. The battery cost would be too great.
That being said, simple1i's suggestion is the watch I ended up purchasing as well - for different reasons. Using any full android phone (Not Android wear, or diluted companion only or minimal call & companion devices) with the screen on all the time will drain the battery fast.
So, you want Full Android utility, so lets talk battery life:
I believe with minimal use (BT pair perhaps) the Inwatch Z (580 mAh) with always on mode active may be able to get a full day (8-12 hours I bet). To compare that, I get around 10 days with BT paired SWApp and the watch screen off (no other modifications, thanks to KK optimizations). 30'ish hours with shake to wake enabled and downclocked to min and 1 core disabled.

yup but the inwatch Z is crazy expensive/overpriced like hell

Which smartwatch to buy under 200€?

I gathered some information in this forum and around the internet and I've found that there are 2 possibilities for me: android wear devices (but the price is higher) and Chinese smartwatches, which seems to be more "complete" as they run a modified version of android (so that play store and other common android features work on the watch). Plus, I'd like to know more about rooting and flashing smartwatches... I see some kingwear, or lemfo lem5 (currently my favourite by design).
Now, is this correct? And if so, what smartwatch would you suggest right now?

I've also found these: FINOW X5: http://www.gearbest.com/smart-watch-phone/pp_576172.html NO.1 D5+: http://www.gearbest.com/smart-watch-phone/pp_446744.html

The only problem i have with the chinese smartwatches (i have 3 different types) is battery life (with the exeption of LEM4 / DM98). I can't get thru the day with one charge. And what good is a smartwatch if it runs out of battery in the middle of the day. It's like wearing a rock around your wrist.
Android wear smartwatches get thru the day on one charge, sometimes even two or three days (i have the LG G watch R, and only have to charge it once in two days). I'm waiting untill the Android Wear 2.0 smartwatches will hit the marked in a few weeks/month to really replace my LG g watch R. Yes, they will be more expensive then the chinese "full android" smartwatches but battery life is important to me.

I don't think battery life would be a problem for me, I would not make an intense use of it. It's more like -when my phone battery runs out, I still have my watch. But ye when the battery runs out the watch becomes a rock. So I should consider battery life of: NO.1 D5+, FINOW X5 PLUS and LEMFO LEM5 (my 3 choices for now). Do you have any of them?

No i don't have those. I have a Q1, LEM4 (sold it recently) and DM368(LF16). And i'm about to sell them all and i will probably wait for the android wear 2.0 smartwatches (although i kinda like the full android type of watches). I did a lot of searching and internet browsing before i bought my watches. And spend a lot of time tweaking them (also rooting them). But as a said, the battery life is a bit of a party crasher for me. I'm looking for a smartwatch that can replace my smartphone on some days. The LEM4 came close, but it's not a very appealing smartwatch, and the Android 4.4 version that i bought (android 5.1 is also available) had a very small app installation partition.
My perfect smartwatch isn't out there yet...

I see, since this would be my first smartwatch ever, I will get the NO.1 D5+ I think cause i like the band and the hardware is really powerful for the price. Who knows, maybe one day i will try one with android wear 2.0 like you. Thanks

Dual Processor-Dual OS with Kospet Optimus Smartwatch, Gimmick or Useful Feature?

The new Kospet smartwatch, Kospet Optimus Smartwatch, it has dual operating system and dual processor, it look like a good feature, but it could be just a gimmick and just little impact on the overall performance of the smartwatch.

when they find the way i will buy it,no reason to buy,is the same Android 7.1 as the others nothing more.For Android act as a phone same problems or issues,not Bluetooth phone call,same display 1.39" , bigger is better as the Lemfo LemX, the resolution i can said better a little,yeah waterproof at least we can swim for 30 minutes,,we dont about the speaker if is louder or decent even the where are place it, Amoled no good for outside. So for the other MCU(SoC) the nordic,can do a lot of more, they call it Lite OS and as you can see and search this SoC in cheaper regular Bluetooth Smartwatch can do; Health,outdoor activities,Bluetooth notfication and call answer and rejection and fitness with better implementation of the GPS..
So will see

The second processor will dig in if you go to the limited mode where you basically don't have a smartwatch, but a watch. Is this what you look for when buying a smartwatch? I would say no. This is a really poor made device imo. With its gigantic battery for a smartwatch it will stay in stand by mode for 5-7 days. Please note that this is only stand by. If you actually use it, it will last 2-3 days(for example take a look at banggood where they list this). Ofc they say this is with 4g, but it is unknown what the "persistent" mode is.

its really a dump idea because its not implemented,for what reason i need a bracelet mode if i am using the watch as a phone and i wont get get nothing,the only way to work is with a second small display in the band.

I had one of the first Kospet devices and I liked it but it lacked the Lite OS and the always on display. I purchased the Optimus Pro and it arrives this week. The 3GB/32GB version.

I just returned my Kospet Optumus Pro - nothing but problems
Pay attention to these details:
Fresh out of the box - you must setup the watch for language and body height/weight/gender - then when the QR code pops up - follow the exact procedure on video below to install the SPECIAL VERSION of WiiWatch 2 app on your Android phone
https://youtu.be/WquMzVsXBmk
Avoid the WiiWatch 2 app on Google Play Store here
https://play.google.com/store/apps/details?id=com.weitetech.WiiWatchPro&hl=en_US
This is crucial procedure for all owners of the Kospet Optimus Pro - as this special WiiWatch 2 app version is required to install all the latest firmware for each processor in the Kospet Optimus Pro
On my Kospet Optimus Pro, problems began right after I installed Google Chrome Browser - (to gain access to all my Google account password credentials for all the URL web sites I participate on ( lots of forums)) - the Heart Monitor stopped working, and the raise watch to enable the watch display stopped working too. Next I entered the new Low Power mode , and thats when I discovered the Watch internal silent alarm buzzer would start, and never stop and just remained buzzing the whole time - sadly I made this discovery after the watch had been sitting on a desk buzzing for 15 minutes straight!
Only recourse is turn off the watch - but that did not function until after I placed the watch in the USB charging cradle , then it responded to the upper right side power button ( long 30 second press) - after a full 2 hour charge , I removed all apps, and verified I had the latest firmware version
Kospet Optimus Pro firmware reports
Build Number = Kospet_Optimus_Pro_V1.5_20190523
KERNEL VERSION = 4.4.22
Thu May 23 16:56 10CST 2019
Baseband Version MOLYLR12A R2.MP.V5.23.P10
SERIAL NUMBER - 0123456789ABCDEF ( WTF?)
Frankly it smells like I may have a counterfeit Optimus Pro - other owners might want to review their "About Watch properties and inspect their serial number , as surely a S/N of "1234567890ABCDEF" is not valid!
https://youtu.be/0Ne11J7U-0w
Here are the results - no third party apps installed and no Sim Card installed
= non stop buzzing in low power mode at all times - and no remedy from Kospet Support -they point me to the useless "FullAndroidWatch.com forum
https://discourse.fullandroidwatch.com/t/kospet-optimus-pro-constant-buzz-in-low-power-mode/47540
And tell me "Update firmware and reset" - did that several times - no fix
Had to return watch to Ebay seller

the most of the apps will work as there is an option to make the screen square. there is also an other option to optimize 3th party apps.
as for the battery life it's not bad at all. I use mine with sim card installed and I did not run out of the juice at the end of the day yet. so surely 1, maybe up to 2 days of "normal" use
in the "long standby" probably a week or two on one charge. I switch between the two modes depending on if I want to take my phone with me or not.
much on this watch remains to be fixed (gps integration with the stock fitness app, a working tethering app etc), but for what I use it ( 2nd phone and audio media consumption) I'd say it's pretty cool.
best regards

Kospet watches are nice to wear BUT they are not compatible with the VERIZON network. Sprint only offers a Dara plan, no voice or text. No matter who you have the phone can not make bluetooth calls.
It turns out to be little more than a wrist watch that doesn't offer near what you think.
