Casio Men’s Vintage CA53WB-1B Calculator Watch

Reboot your retro style with a timepiece take on the Casio Mini, the trailblazing Casio calculator. The long-selling calculator watch from Casio, the CA-53, pays homage to the Casio Mini, the world’s first personal calculator, featuring the original colors and design of this legendary, groundbreaking calculator. The unique design of this watch face features a calculator-style combination of LCD and full keypad, incorporating design motifs from the original Casio Mini introduced in 1972. The display employs green text on a negative LCD, and the keypad uses the font from the original, with each key separated by a grid line. The use of red for the mode indicator at the upper right evokes the image of the calculator’s power light. Every detail, down to the white lines along the top and bottom of the watch face, projects retro-modern calculator style. In addition to a calculator function that adds, subtracts, multiplies, and divides up to eight digits, the watch also comes equipped with dual time, stopwatch, alarm, and more. The band is made of bio-based resin, a material expected to help reduce environmental impact. Casio Mini, the world’s first personal calculator In 1972, Casio debuted the world’s first personal calculator. With one-chip large-scale integrated circuits (LSI), a six-digit display, and simple componentry, it was a quarter the size of mainstream models at the time, and at 12,800 yen, it cost just a third of competing products. The Casio Mini became a mega hit, selling one million units in the 10 months after its release and a total of six million units over the course of the series. With the Casio Mini, the calculator moved beyond office equipment, becoming part of everyday life as a personal household item. In 2008, the Caso Mini attained an Essential Historical Materials for Science and Technology (or Future Technology Heritage) designation from the National Museum of Nature and Science in Tokyo
