Casio Collection Watch W-220HF-3AVEF

Introducing the Casio W-220HF-3AVEF, a digital outdoor watch that combines materials and colors with a visual coherence rarely found at its price point. The round case is finished in matte military green, framed by a black bezel marked with ADJUST, MODE, SPLIT and START in white, and the word ILLUMINATOR in orange at the top. The inner bezel ring houses a small function selector dial with indicators: SIGNAL, A.LIGHT, SPLIT/ALARM and AUTO LIGHT ON/OFF. At the lower part of the module, a dark brown strip carries the word LIGHT in orange lettering. The strap is one of the most distinctive details: it pairs dark brown stitched leather on the outer face with olive green nylon on the inner side that contacts the wrist, creating a two-tone effect that reinforces the military aesthetic of the whole piece. The buckle is silver-tone steel. ALARM CHRONO is embossed on the lower strap section.

The dial is a liquid crystal digital display on a black background. The upper section reads CASIO with WR AUTO LIGHT SWITCH and ALARM CHRONO. The large central area displays the time in 12 or 24-hour format with wide, highly legible digits. Above it, the abbreviated day of the week and the set alarm time are shown. A numerical scale from 02 to 10 serves as a visual seconds reference. At the bottom of the dial, mode indicators TR, ST, AL and DT are visible. Module 3549 delivers the following functions: time and auto-calendar, daily alarm with beep signal, 1/100-second stopwatch up to 24 hours, 12/24-hour format, automatic wrist-tilt backlight (Auto Light Switch) and manual Illuminator backlight. The watch is water resistant to 50 meters, suitable for swimming and rain.

The W-220HF-3AVEF belongs to the Casio Timeless Collection, the classic digital watch line that since the 1980s has defined practical utility accessible to everyone. These models inherit the DNA of the first Casio digitals: toughness, functionality, and a design that never ages. The outdoor aesthetic of this reference, with its palette of green, brown and orange, connects directly to the tradition of field and adventure watches that Casio has cultivated for decades.
