Casio CA53WB-3B Heritage

Revive your retro vibe with the Casio CA-53, a modern reinterpretation of the classic Casio Mini calculator from 1972. This watch captures the essence of the original, featuring a calculator-style LCD display and a full keypad, with green text on a negative LCD and a red mode indicator—paying tribute to the pioneering design of the Casio Mini.

In addition to its nostalgic look, the CA-53 offers practical features, including a calculator for basic math, dual time, a stopwatch, and an alarm. The bio-based resin band also contributes to a more eco-friendly design.

Released in 1972, the Casio Mini was the first personal calculator, known for its compact size and affordability. It became a massive success, selling six million units, and was later honoured by Japan’s National Museum of Nature and Science for its historical significance.
