The three new watches Casio has released in its Classic collection look so familiar that many people probably won’t even think they’re new, or even from this decade, for that matter. With the nostalgic look of the ubiquitous digital watches from 1980s like the plastic-classic F-91W, these retain all the features and qualities qualities you either love or hate. They’re small, thin, and light; they cost about as little as any watch could, and they pack in a surprising amount of functionality. They light up. They beep.
