Beautiful modern and satisfying watch. I have a mobile phone Haier W970 and was able without any difficulty connecting with the watch Sony. Really handy to not miss to call and discreetly read text messages during meetings. I am very happy with this watch with great value for money. Only the extension for email only works for the Sony phone owners, but hey, it's not too bad for me. However, I suggest that you change the bracelet for he that comes standard rubber is poor and takes too hot.
