Hello,
This will be a quick review of LOKMAT watch with bluetooth.
I will divide it into several parts:
- Design
- Hardware quality
- Software
- Firmware
Design
The watch looks nice on the first glance. A simple watch with bluetooth connectivity and "reversed LCD" (digits are light while background is dark).
It is not so simple to set it up - but there is an instruction (English only) attached.
Hardware
Pretty good - except the glass. I have broken mine quite easily.
Back plate is "stainless steel" according to the label. Once removed - it is very difficult to mount it back.
There are 4 buttons. One to turn on night light and turn on Bluetooth. One to show statistics (steps, etc.). Other are too complex to use.
The watch feels pretty large and heavy. I had larger and heavier watches... but this one just doesn't feel well on the hand.
Strap is some kind of rubber. It has two loops to keep the strap close - a good thing.
Inside there is a sticker saying that quality check has passed.
Bluetooth is 4.0 low energy. It is loosing connectivity often so you need to turn on the Bluetooth once in a while to connect it back. Bluetooth is loosing connectivity once disconnected for a while (it is good as it won't drain the battery but bad also as you won't re-connect automatically).
Button 1 (top left) will enable dimmed light and will enable/disable Bluetooth when pressed for some longer time.
Manufacturer promised 6 months of usage when Bluetooth is on. And waterproof case up to 50 meters of depth.
Software
Weakest part of the watch. Poor translation, not much functionality. And it looses all the statistics after watch restart.
It has nice backgrounds - if you like looking at pictures then it is nice. But if you prefer functionality over the look..... well... buy another one.
Application drains battery a bit. But only a bit.
After connected - it will set up the clock and date. Very nice thing.
Firmware
All the icons are "on" by default. If you expect to be informed about important events such as incoming SMS or a call... it is a bad choice.
You won't be able to use the watch for anything else than pre-defined features as the software is closed source and the communication protocols are "custom".
Summary
I liked the watch (until the glass broke). For the price ($15) I would expect a bit more - but the price is not that bad either.
I would imagine that the watch could be really nice if they would:
- release the firmware source
- release API documentation for the communication protocol
- improve the case back plate and glass
