So I am very pleased with the clock. By design they like best the current Smart Watches with the exception of Apple clock EVT. The apple has just really on it. Only the operating system and the dependence go do not fit unfortunately. The tape of Sony is very light, but still feels very valuable and robust to. She must have omitted the glass to remuneration probably have something to do with the price, not nice but I can live with - the film of Mumbi is acceptable. Heart rate monitor I do not need when I train I take the chest strap - Eh accurate than so ne photometry. GPS is cool if you are on foot. Software Technically Androidwatches are anyway all the same but it is waterproof and runs smoothly. Use them also like as a monitor for my IP Cams or mp3 player while biking and 2 of 4GB is more than enough for songs. On the subject of "Who needs a SmartWatch?" As long as the clock does not have any Sim I can see all the information on your phone. So sogesehen it is really just ne relief so I do not always dig out the phone or have to carry around as long as the home or office are not greater than 9m. However, if the WLAN support, hopefully coming soon that's really cool not always having to have the giant smartphone. You get used to inform surprisingly quickly to the new style. Achso often the battery life will be discussed. So let's face it as long as we are not in the age of the fuel cell can be surely live wonderfully with a charging time of 1-2 hours. When I come home in the evening and make myself fresh I hang the clock on the loaders, go eat something and then she is already fit again until the next day and in the early days where you still much rumfummelt tuned. What happens, of course, when the battery time has its cycles behind them remains to be seen. The but the Sony is the only one with a direct micro-USB connector, I do not understand - Who wants to even the charger to carry around with ... I have not even tried the clock to load via NFC, tomorrow in the same company time to try. Whether it's just a HIPE? Do not think so! I have replaced recently my flat screen TV against a UHD SmartTV with Prime (Will lately somehow everything Smart ...) and actually realized that the way remote watching but has improved tremendously. In about as I see it with the Smart Watches - Of course it's a gadget but gadgets are now time to as to us to make everyday life easier. So bring it on ;-) Incidentally also find it more politely looking at the clock to as always staring into the phone! In my opinion, makes the Sony for all that need to remain inconspicuous on the ongoing / want to sense. It is upscale, chic, fast, well priced and is comfortable to wear throughout the day and even beyond.
