Hi david91408,
You have to start this timesetting procedure by pressing button "A" upper left, while in standard timekeeping mode. The "seconds" will start flashing.
Then press "C" lower left to cycle through the various modes. Each further press will cycle as follows: Seconds >> Hours >> Minutes >> Year >> Month >> Date...then back to Seconds.
While in each mode, press "E" lower right monentarily and continuously to change to the correct time and date. Remember to press "C" after each change.
Be aware of "PM" indicator to make sure you get the watch timing correct in order to roll over the date at midnight.
When done press "A" again to go back to standard mode.
It appears your watch module is #1289. You can also download a PDF manual here for more complete operation of all facets of your watch:
