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.\n\nIn 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.\n\nReleased 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.\n\n- 43.2 × 34.4 × 8.2mm Case Size \n- 25g Weight\n- Resin Case and Bezel Material\n- Bio-based Resin Band\n- Water Resistant\n- Approx. battery life: 5 years on CR2016\n- Resin Glass\n- World time: Dual time\n- Stopwatch\n- Alarm\/hourly time signal: Daily alarm\n- Calendar: Full auto-calendar (to year 2099)\n- Mute feature: Button operation tone on\/off\n- Accuracy: ±15 seconds per month\n- 8-digit calculator\n- 12\/24-hour format\n- Regular timekeeping: Hour, minute, second, am\/pm, year, month, date, day","brand":"Casio","offers":[{"title":"Default Title","offer_id":45807219048666,"sku":"30271308","price":59.0,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0642\/0561\/9418\/files\/30271308-a.jpg?v=1732695815","url":"https:\/\/www.grahams.com.au\/products\/casio-ca53wb-3b-heritage-30271308","provider":"Grahams Jewellers","version":"1.0","type":"link"}
