Hi, This watch is Calibre C651, same as Model #JR3090-58M (Promaster Air Collection - Blue Angels Skyhawk). C651 is not available on Citizen website, but you can use Calibre C650 instructions. Download PDF manual and follow instructions on page 3. They are pretty detailed, so take your time, and you should be successful. If you don't have the manual, Try this link:

Take the four-digit Calibre number (C651 or C650 in this case) from the back of the watch, enter it, and download a PDF of your watch setting-instructions/manual.
I hope this helps you. Thanks, Bill
