CasioGeneral Men's Watches Data Bank DB-36-9AVSDF - WW

A basic retro Casio digital watch in the 1980s style, this model is easy to configure with a decent LED backlight. It's missing some bells and whistles (no game and watch here; support for a few time zones would be nice), but the price is right. I've worn this watch in saunas and swimming in the ocean and had no problems with its waterproofing.
