I like the Nixon Harmony, does a lot of things, and its especially nice if your vision isn't perfect, it has a night light and you can enlarge the numbers so you can see them. It's water resistant to 100 m. and its small, made for a woman's wrist. Actually, I like this company so much I own 4 of their watches and they all are so comfortable to wear. Also, reasonably priced, under $100.
