Query: Great nerd watch!

I had several of these Casio data bank watches over the years, all black plastic. The last couple all had pieces physically break off, where the watch band connects. Too cheap! I thought I'd try a metal one (even though I don't like how the band can pull my hair, I've gotten used to it). It has all the great features of the old watches I had, and it's lasted over a year now!!!
