I'm not sure how to set my champion digital watch from target!

I am having the same problem. The battery is fine, the seconds are ticking away, but none of the side buttons work. The light doesn't come on and nothing happens with any of the others either. The only thing that did work was pressing all four of the buttons simultaneously, which seemed to totally reset the watch. The problem is it reset but didn't fix the buttons. So now I can't even see the correct time anymore.

Reset it by removing the battery.

to change the battery in a champion watch:
(1) remove the back, (2) carefully peel loose the foam strip and set it aside (3) release the battery retaining bracket with a needle or awl and tweezers, (4) grasp the case with your thumb and forefinger so that your thumb is holding the works inside the case, (5) turn the watch over and the battery should fall out (6) put the new battery in the holder, (7) snap the retaining bracket back in place (8) replace the foam strip (9) replace the back

PUT it under the light

Hold the bottom right button (lap/reset) until it beeps and comes up with "SET". The bottom left button (mode) will alternate between what you are increasing (Hour, minute, month, day, ect) and the top right (start/stop) will increase it by one (hold to make it go faster). When done, just hit the bottom right button again.

The manual should be here.

On the C9 Fast Wrap Strap digital watch, press and hold the "LAP/RST" button until the display shows "SET" then release. Use the "MODE" button to switch between second, minute, hour, etc. Use the "ST/STP" button to change. Press and release the "LAP/RST" button to exit. The Sportline might be the same or similar.
