I had one problem setting up the watch. It asked for a password when I was copying my Google Account to the watch, but my Google password would not work. It turned out it wanted my phone lock screen password, and I wasn't expecting this. Once I overcame that, the watch was excellent.
I have worn Citizen watches for many years and was excited to see that smart watches were available. the other brands seem more sporty and for younger demographics, the Citizen looks more like a classic watch, round face vs. square, metal link band you name it. Very happy with this product so far.
I like the watch, but battery time is very short and the sleep interface doesn't capture all sleep time, and it is not possible to edit. Since that is my main reason for the watch, I am returning it.
Watch isn't holding a charge. Can't go 24 hours without losing the charge. Thus, my steps and everything are not accurate
