Embrace retro style with the Casio CA-53, a contemporary take on the legendary Casio Mini calculator from 1972. This watch reimagines the original with a calculator-style LCD display and full keypad, featuring green text on a negative LCD and a red mode indicator, staying true to the iconic design of the Casio Mini.

The CA-53 isn’t just about looks; it also offers practical functions like a calculator for basic calculations, dual time, a stopwatch, and an alarm. The bio-based resin band adds an eco-friendly touch.

The Casio Mini, introduced in 1972, was the first personal calculator, known for its compact design and affordability. It sold six million units and was later recognized by Japan’s National Museum of Nature and Science for its technological importance.
