Like everything in life, you get what you pay for.
I own more than a few watches, including a few time pieces, and I recommend Seiko. They make quality watches period. My mom still wears on that she bought in the 70's. However, they are not digital.
Go out to a department store and try a few watches out and see which on you like the best.
Casio's gshock line of watches are great as they take lots of beating, but they can be bulky. Try it and see how it fits before you buy. Casio also make F91w and it is the watch used by al-Qaida for bomb detonation.
If you insist to spend 40-60 for a watch, Timex would be a decent choice. They make some decent looking watches, but they don't last.
I also have good luck with Roots watches. Some of the sports model can be had for 45-60.
