Which casio ?

Which is the casio with a stopwatch, timer, preferably a calculator .. and cool bonuses or colours I'm open to. Preferably not crazy money but open to seeing them anyway. Anything better than the Casio Data Bank DBC-32 (doesn't have timer)? Im sure there are but there's so many variations I know someone here will know better than me. Second hand old watches are fine just don't know which to look for
