The design is simple, elegant, a single power button, a charging socket. The watch is waterproof.
I use it for 2 days and the battery is at 82%. Regarding my use is mainly: Time display and notification display to avoid picking up the phone and see a message like "Ok", one leaves his watch and it's good.
The configuration is simple to perform, simply install SmartConnect Sony. It is compatible with Android, I currently use my watch with a Galaxy Note 2, perfectly compatible, I get a message alert on the watch.
The application to control the phone's camera I do not use it because I do not find it terrible ...
