I wanted a watch for a younger girl and I've always had good luck with Casio watches. They are very reliable and have the features I like. Features I like that are on this watch:
Low price and reliable maker
10 year lithium battery
50m water proof
Smaller design, while not as small as a "woman's" watch it has more features and is smaller than the normal "man's" watch
Indigo back-lite
Easy to set time and recessed adjust button(won't get accidentally bumped).

12/'12 Well watch was lost so I'll be ordering a couple more from Amazon. Can't believe this watch is only 12 bucks shipped, even with 25% off sales at local B&M it's still cheaper to buy at Amazon. Oh after  over 2 years watch was still working great, just got lost :(
