This watch is really slim and light weight. I ordered it for my brother and he has been wearing it for 3 months now, it works amazing. Its battery lasts for about 7-12 days. I offers an app which has an option for custom faces. The watch come with pre loaded 3 faces but in the app you get 100+ customisable faces for the watch. You can even set an image as the face of the watch. Thats amazing!
