Watch is great revolutionary piece amongst the Casio g shock series.
Just wana tell.it connects to other phones too apart from iPhone and high end galaxy series.
I own YU yureka and it work perfectly fine.
Cons -
Didn’t like the light functioning of watch.
Just a glow of few inner LEDs.
No glowing of digital numbers or the rotating dials of clock.
Does not work with android phones correctly. There is a preference towards Samsung as the apps made in android are only made to work on Samsung’s high end galaxy series S5, S6 etc. The watch is however is very funky, really loved it but in my case the Bluetooth connectivity is not working.
