Wal-Mart sells affordable watches by the company Athletic Works. It's sometimes common to throw away the directions, only to discover later you can't figure out how to set the watch. The problem is that Athletic House doesn't have a website or any manual online, so you may have difficulty getting help unless you find someone who also has the watch.
There should be four buttons: mode, reset, start and light. Find the mode button and press it three times until it is in the set time mode.
Find the reset button, which usually is located on the bottom right side of the watch face, and hold it until the time starts blinking.
Press the start button to change minutes.
Press the reset button again to switch to hours. You will know it worked when the hour starts blinking instead of the minutes.
Press the start button to change the hour. The watch can handle two modes: standard and military. As you press start, the hour will change from AM to PM, noted by an "A" or a "P" in the top right. When you get through 24 hours, the watch will change to military time and an "H" will be displayed instead of "A" or "P." Keep pressing start to go through another 24-hour cycle and it will revert back to standard time.
Press the reset button to switch to the date, starting with the month, and press start to change it.
Press reset one last time to switch from month to the day, and again press the start button to switch days.
Press the mode button to finish the changes.
