What Casio digital watches actually use metal?

I really like the sleek look of old casiotron watches. Which modern Casios are actually made from metal and not chromed resin? Are there any that resemble the original line of 70s Casiotrons? I am thinking of getting the A700 but I don't know how durable said resin is, how does it keep up over time with scratches and bumps?

Thanks for all the answers in advance.
