The Casio AQ-240E-3ADF brings a modern refinement to Casio’s classic vintage analog-digital aesthetic. The watch features a slightly rectangular face with softly rounded case edges, a blue-green sunray-finish dial, metallic indexes, and a digital LCD positioned at 6 o’clock. This creates a balanced combination of traditional analog styling and useful digital functionality.

The analog display uses two hands for hours and minutes, while the digital section displays the hour, minute, second, PM indicator, month, date, and day. The dual-time function allows you to monitor a second city or time zone, making the watch particularly useful for travel and everyday time-zone tracking.

For additional functionality, the AQ-240E-3ADF includes a 1/100-second stopwatch with a maximum measurement of 59 minutes 59.99 seconds, a daily alarm, hourly time signal, and an auto-calendar designed for 28 days in February. It also supports both 12-hour and 24-hour formats.

The watch measures 40.9 × 35.8 × 8.1 mm and weighs just 51 g. Its stainless steel bracelet has an adjustable clasp and accommodates wrists approximately 150–205 mm. The resin/glass crystal and water-resistant construction make it practical for everyday use.
