Have the part with me - yes - is always nice and even working a bit with iPhone. (Call list, call answering calls at a moderate audio quality / Sim and memory card I have not tried, for that I would have the clock screw) For me, the camera and also another app crashes on the clock from now and Watch goes to Freeze ( which is the other, I do not know, it's manual nil.) calendar data and other message apps should not go on the iPhone. The small robots there's an app that can be installed so that these messages are pushed to the clock. Battery suffering on both sides, of course, considerable, because yes Bluetooth connection must be constantly maintained (is then also in the iWatch to worry about). In fact, I use the clock now only to display my time. But one has rather moderate well-designed 4 analog and 3 digital designs to choose from. Operation via the touch screen is, however, refreshing well what hope is that then also the iWatch works. Furthermore me the bracelet is too short, so the clock is not likely to live long, because it will fall down if I is away with the loop, stuck somewhere. Conclusion - the only positive thing about the clock is that it is earlier than the iWatch outside and they may look a bit like her. If the first run with the real yells sure nobody after this clock. The concept of iWatch is a completely different and I'm sure that Apple will make it again to show everyone how to do paired wrist part with the iPhone really reasonably usable.
