I've always wanted light up digital watch like this since I was 7. And that's exactly what this watch is.
REMEMBER 3 stars means "It's okay"

pros:
 - tells time, day, and date
 - has an alarm clock, hour chime, and stopwatch
 - water proofed enough to stand being on the wrist while washing the hands, and up to 30 meters. (eg. no scuba-diving)
 - despite what other users have said, I've run the watch under a tap, and noticed no water- but it wasn't for very long.
 - it has a light
 - the band is easily re-adjustable
cons:
 - the metal feels cheep and flimsy
 - the light is only one side, not evenly lighting the face of the watch.
 - and finally - this is a personal one which won't apply but to guys - if you're a hairy dude, the watch links will catch and pull every once in awhile, so be sure to not be too touchy about it.
