CASIO VINTAGE AQ-240E-2ADF ANALOG-DIGITAL LIGHT BLUE SUNRAY WATCH

The AQ-240E-2ADF is the next evolution of Casio's long-running AQ-230 — the same retro analog-digital DNA, widened into a more contemporary silhouette with softer contours and a bigger canvas for colour. The light blue sunray dial catches light differently at every angle, shifting from pale sky to deeper ocean tones depending on how your wrist turns. Chrome-plated resin case, slim silver-tone analog hands, a small digital window at 6 o'clock showing day, date, and seconds — all sitting on a stainless steel bracelet with oblong horizontal links that lay flat against the wrist.

Module 5154 keeps the feature set deliberately simple: analog hour and minute hands over a dual-display layout with digital readout, dual time, 1/100-second stopwatch (elapsed time), daily alarm with hourly time signal, and a 12/24-hour format toggle. At 40.9 × 35.8 × 8.1 mm and 51 grams, the AQ-240E wears slightly wider than the AQ-230 but at the same slim 8.1 mm thickness — just enough presence to fill the wrist without bulk. The self-adjustable stainless steel clasp means you can size the bracelet yourself without tools or a trip to the store. SR920W battery, approximately three-year life.

At a Glance

Why You'll Love It

• The light blue sunray dial is what makes this variant stand out from the rest of the AQ-240 lineup. Sunray finishing means the colour shifts with light — cooler and paler under overcast skies, warmer and more saturated in direct sunlight. It's a dial that looks different every time you glance at it, without being loud about it.
• The AQ-240 silhouette is the wider, more refined successor to the AQ-230. The case has subtly rounded contours instead of sharp edges — Casio calls it "gentle curves on the bezel top" — which gives the watch a softer, more contemporary feel while keeping the retro rectangular shape. It fills the wrist better than the AQ-230 without adding bulk, staying at just 8.1 mm thin.
• The stainless steel bracelet uses oblong horizontal links that lay flat — no lifted segments, no catching on sleeves. The self-adjustable clasp lets you size it at home without tools or a store visit, though complimentary strap adjustment is available at any City Chain outlet.
• Analog hands over a digital sub-display at 6 o'clock is the classic Casio dual-display layout — you get the glanceability of analog hands for telling time quickly, plus the precision of digital for seconds, day, and date. Two information layers in one clean dial.
• At 51 grams on a stainless steel bracelet, this is a light, slim watch that wears like jewellery rather than a sports instrument. The chrome-plated case and silver-tone bracelet pair with the cool blue dial for a clean, fresh combination that works in both casual and smart-casual settings.
• Three-year battery life on an SR920W. No charging, no solar panel management — set it once, wear it for three years, replace the battery when the time comes.
