Step into the world of retro style with the Casio CA-53. This watch takes inspiration from the legendary 1972 Casio Mini calculator. It features a calculator-style LCD display with green text on a negative LCD and a red mode indicator, just like the original. With a full keypad, it stays true to the iconic design of the Casio Mini. The CA-53 is not only stylish but also practical. It comes with functions like a calculator for basic math, dual time, a stopwatch, and an alarm. The eco-friendly bio-based resin band is a great plus. The 1972 Casio Mini was the first personal calculator, known for its small size and low price. It sold six million units and was recognized by Japan’s National Museum of Nature and Science for its tech importance. It has a 43.2 × 34.4 × 8.2mm case size, weighs 25g, and has a resin case, bezel, and glass. The watch is water-resistant, with an approximate battery life of 5 years on a CR2016. It offers world time (dual time), a stopwatch, a daily alarm, a full auto-calendar until 2099, a mute feature, an 8-digit calculator, and both 12/24-hour formats for regular timekeeping.
Using your Casio CA53WB-1B Heritage watch is easy. To use the calculator, just press the keys on the full keypad. For setting the dual time, look for the mode button and follow the prompts on the display. The stopwatch can be started, stopped, and reset with the dedicated buttons. To set the alarm, find the alarm - setting function and set the time you want. Remember, this watch is water - resistant, but don't swim or dive with it for long periods. When it comes to battery replacement, wait until the watch starts to show signs of low power. Replace the CR2016 battery carefully to avoid any damage. Clean the watch regularly with a soft, dry cloth to keep it looking good. Also, keep it away from extreme temperatures and strong magnetic fields to ensure accurate timekeeping.
