The base model is the CA-500, a long-selling CALCULATOR model from Casio watches that has been around since the 1980s. The motif of the DeLorean, which symbolizes the work, is used on the face to vividly express the world of the movie. Furthermore, the multi-color around the buttons, which is inspired by the "time circuit," a device for setting the destination time in the DeLorean, gives you a sense of traveling to the future. The back cover is engraved with the "flux capacitor," a device that is essential for time travel in the movie. The clasp is decorated with the "Back to the Future" logo, paying attention to every detail. The special package, which looks like a video tape, also reflects the world of the movie.
