Got this as an early Fathers day gift from my kids. Love it.
Beautiful watch - easy set up, and it was nearly fully charged out of the box. I like that I can check for atomic syncing at any time I wish, or just let the watch do everything automatically. And no more major programming efforts city by city when daylight savings begins or ends! All the listed features work as advertised. The manual is online, and watch warranty registration is by app. The app needs a bit of work, but in the end just make sure to keep evidence of purchase if you do need warranty service. One last thing - I found it by accident, but if you search for ‘Citizen U680’ (U680 being the movement designation of this watch) the full and an abbreviated (4 page) manual will pop up next to each other in the results. Save both to your Reading List or Bookmarks, and you can play with the various settings and features during down times. Not too complex at all - just appears that way at first. Very highly recommended!
