To set an Armitron Wr330 watch, use the buttons on the upper and lower left- and right-hand sides of the watch to manipulate the seconds, minutes, hours and day date. Hold the top-left button until the seconds flash, then hold the top-right button to zero them out. Hold the bottom-left button until the hours flash, then press the top right button to change to the desired hour. Repeat the last two steps to set minutes, month and date.
Set the minutes by pressing the Mode button, located on the bottom left-hand side of the watch. Hold it until the minutes begin to blink, and continue holding it until the desired time appears. The steps are identical for changing the month and day date. Simply press the Mode button, and hold it until the desired unit of time appears on the screen. If desired, set the alarm time by holding the Mode button until the alarm hours flash, then hold the Alarm button, located on the upper left-hand side of the watch to advance them. Once the month, day date, hours, minute and alarm are set to your satisfaction, confirm the changes by pressing the button on the bottom, left-hand side of the watch.
