Have wr 200 citizen watch. how can I set the correct year to 2010. It always reverts back to 2016

I'll need more information about the watch. WR200 is not the model number. It is the depth in metres it is water resistant to.
The serial number is usually engraved on the back plate of the watch. The bit against your skin when you're wearing it. It's the number marked in red in the photo I've attached. Is this a digital watch, a watch with hands or does it have both?
Comment below with the serial number and I'll try to help you more.

If this does not help I suggest that you contact them and discuss your problem. The web site indicates that there a 5 year warranty on their watches. If this applies to your watch, then they should repair it free of charge.

My watch is experiencing the same problem. I just found out the following on Citizen's website:
"The factory has discovered a software anomaly in the calendar programming of the integrated circuit that affects some Skyhawk AT and other styles utilizing the U600 movement caliber produced in only 2007 for those watches receiving either the U.S. or Japanese time signals. Those customers receiving the German time signals or have pieces manufactured in other years are not affected. This anomaly results in the calendar displaying dates from 2016 even though the year is 2010."
It goes on to say that the watch needs to be sent in for a software update. Below is a link to the FAQ topic:

Sorry, I don't have a solution to this problem but I am experiencing the exact same problem with my Citizen Eco Drive Skyhawk A-T (JY0000-53E). It automatically sets the year to 2016 and the day to the previous day. For example, if it's currently Tuesday, the watch will indicate that it's Monday. And instead of the year being 2010, the watch will indicate that it's 2016. I have to reset my watch daily. I'm not really sure how long my watch has had this issue but I first noticed it in March, 2010.

who set set it these have a 5yr guarantee so send it back to citizen ,it may need a new capacitor this is like a battery but it stores the power from solar panel on the face of your watch these always need replacing at sometime within the 5yrs. because it can cause the functions of the watch to malfunction. if you not got the guarantee try a good repairer they may be cheaper then sending bk without guarantee
