This is a very rare version of these models of casio ani digital watches based after the amw platform. Most that you will see is the amw 320 which had a straight digital read out but on this much more rarer ad 520 model the digital display is curved hence the nickname "smile" or "Smiley". The amw models in this color scheme are also referred to as "Arnies" because arnold schwarzenegger wore this exact model in several movies he was in..likely it was his personal watch or you wouldn't see him wearing it in everything from kindergarten cop to jingle all the way to true lies. This watch is in excellent condition from a jewelers estate.
