Revive your retro style with a watch inspired by the Casio Mini, the innovative Casio calculator.

The CA-53, Casio’s best-selling calculator watch, pays homage to the Casio Mini, the world’s first personal calculator, by bringing back the original colors and design of this legendary and revolutionary calculator.

The unique design of this watch features a combination dial with LCD and full keypad that follows the style of the calculator, taking the shape of the original Casio Mini introduced in 1972. In the display the text is green on a negative LCD and the keypad uses the font of the original version, with each key separated by a grid line. The use of red for the mode indicator at the top 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 a retro-modern calculator style.

In addition to the calculator function that performs addition, subtraction, multiplication and division of up to eight digits, the watch also features dual time, stopwatch, alarm and more.

The strap is made with bio-based resin, a material designed to help reduce environmental impact.

In 1972, Casio introduced the world’s first personal calculator. With single-chip large-scale integrated circuits (LSIs), a six-digit display, and simple componentry, it was a quarter of the size of mainstream models at the time, and at 12,800 yen, it cost only a third of competing products. The Casio Mini became a huge success, selling one million units in the 10 months following its release and a total of six million units over the course of the series. With the Casio Mini, the calculator went beyond office equipment, becoming part of everyday life as a personal household item. In 2008, the SL-800 was designated as an essential historical material for science and technology (or heritage for future technology) by the National Museum of Nature and Science in Tokyo, as it is an extraordinarily thin and compact calculator.
