Watch shuts off when I press the light button. When I press it, the temp only lights off then the rest is gone

Muhammad, take a pen and repeatedly stab the light button 20x,
to un stick button, if this does not do it, change the battery, as it is probably weak.

it needs a new battery

There is a button with an atomic time symbol below the face of the watch. Press and hold this button until you hear a beep and the light will go off. To turn it back on again, just press and hold that same button until you hear a beep and it will come back in automatically when you tilt your watch.

think of the top buttons from left to right as A & B and the bottom buttons from left to right as C & D. The way to turn the chime off and on is by holding the C & D Buttons simatainiously and the pressing the B button. This will allow you to turn the Hourly Chime Off and On. When you see the digital chime pattern in the display the chime is on. When no pattern is shown the chime is off. Hope this helps the ton of people who have purchased these watches & either did not have instructions with or lost them. This perticular watch has been annoying the whole household for quite sometime and has now been put to rest..lol
