I bought my fist Citizen many years ago. I travel 45 weeks a year and the world time is perfect. I now own 8 world time A-T Citizen watches, yes several duplicates.
Very mice watch looks great works great only complaint very difficult to set the watch the Manuel leave a lot to be desired ! I have numerous Citizen watches this is the worst to set time and date !
I bought this watch 10 years ago and never had to do anything with it. Great features with the time, 24 hr, day and perpetual calendar. Plenty of features.
