Casio CA-53W

The Casio CA-53W is a digital calculator watch made by the Japanese electronics company Casio, introduced in 1988 as a successor to the CA-50. It became culturally prominent through its appearances on screen, worn in the science fiction films Back to the Future Part II (1989) and Back to the Future Part III (1990) and later worn by the main character throughout the television series Breaking Bad (2008 to 2013); although often associated with the original 1985 Back to the Future film, the CA-53W was not actually worn in that movie, where the earlier CA-50 model appeared instead, and the CA-53W features only in the two sequels.
