The Casio CA-50 is a black-resin calculator watch introduced in 1984, with module 437 driving an eight-digit calculator operated through membrane keys below the display. (Digital-Watch.com) It preceded the near-identical CA-53W that replaced it in 1988; the silver Casio CA-500WEBF-1A is a separate 2025 anniversary model. (Wikipedia)
The model worn by Marty McFly remains disputed. Casio's 2025 press release calls it a CA-500, while the anniversary product page calls it "Marty's original CA-53"; neither names the CA-50. This catalog's identification rests on the film frames and collector documentation rather than the brand's conflicting retrospective copy.
