The clock does exactly what it should. It is an extension of the mobile phone displays. And that is why I have brought me. I Tizen (ie the latest update from Samsung) installed. With Android it was worse to classes. For me it is important that I can read WhatsApp and emails. And that works great. Only answers can not unfortunately. For this, the display would be too small. The display is crisp sharp and not exaggerated color. The battery lasts loose two days before by the Gear has on the charger. So just as long as my S3. When new messages you will be made either by sound or, I think attention to weak vibration. What I feel is pleasant is that the clock is also a speakerphone. The understanding about it comfortably and clearly.
My conclusion: A useful gadget for a now acceptable price.
