Watch how do i change the date on my citizen ecodrive perpetual calendar

You should be able to pull the crown out 1/2 way and turn the crown clock-wise and you should hear a click and the calender should move one day. Don't change when the hands when the time is between 10 and 2 , just manually move the hands past that time , and re-set afterwards. If that dosn't work let me know ,.There are other types of those watches , but the way I told you is the most common.
