The clock is supplied with a sturdy paper / cardboard, which is perfectly adequate for use for transport. Included is a manual in English and Chinese. As a default setting, the clock is set English, so you can easily change the language to German in the settings. My claim to a SmartWatch was to purchase a relatively inexpensive clock which sent me messages of Messenger (Telegram, threema, Simsme, SMS), and information about incoming mail from my iPhone. That to this clock a telephony function is still functioning, is of secondary importance to me. I must say that this clock met my expectations more than we thought. To be informed about incoming messages, without the iPhone has to be taken out of his pocket, is pretty nifty. And there must be no iWatch ... Well, pedometer, sleep monitoring, compass and other functions on top complement the functionality of this clock. Who needs it ... The bracelet and the case of plastic bothers me personally less. With caution should however take the water resistance, the openings for the micro USB connector (although with cover) and to the small speaker seem me very doubtful to be tight. However, I do not intend to take this clock with a bath ... Another phrase for endurance: With a single charge you get loose with moderate use over two days, I think. But here I'm still missing "runtime experience" in order to give a more accurate assessment. Oh, an app in the AppStore, there are also to be these used to log the fitness program. Control of the clock through the iPhone does not work, that would be asking too much for this price.
