Premium Design

The Casio W-221H-1AVDF showcases a distinctly geometric, bold angular structure that stands out in any casual setting. Its matte black finish radiates a clean, stealthy aesthetic suitable for sport and everyday wear. Built using high-impact resin materials, the case absorbs everyday shocks and minor bumps effortless while keeping the total weight exceptionally light at just 35 grams.

Dial Features

Designed for maximum visual legibility at a glance, the watch features a large, high-contrast digital LCD panel. Time, date, day of the week, and active mode indicators are organized neatly across the main screen. For nighttime visibility or low-light conditions, an integrated amber LED backlight illuminates the screen evenly with a selectable lighting duration of 1.5 or 3 seconds with afterglow.

Case Features

Measuring 43.7mm in length, 38.4mm in width, and 12.2mm in thickness, the compact resin case offers a perfectly balanced proportion on wrists of varying sizes. Tough resin glass protects the digital module against daily scratches, while four dedicated function side buttons provide tactile, immediate feedback for setting alarms, timers, and toggling world time modes.

Movement

At the core of the Casio W-221H-1AVDF is a high-precision Japanese quartz digital movement operating at an accuracy of ±30 seconds per month. Powered by an ultra-efficient CR2032 lithium battery cell, the movement offers a staggering 10-year battery life, freeing you from frequent battery replacements and ensuring years of continuous, dependable timekeeping.

Strap/Bracelet

Fitted with a durable black resin strap and a secure pin-buckle closure, this watch stays firmly anchored during physical activities. The flexible resin band is moisture-resistant, easy to clean, and fully adjustable to accommodate wrist sizes ranging from 145mm to 215mm.

Water Resistance

Engineered to handle active daily environments, the Casio W-221H-1AVDF features 50-meter (5 bar) water resistance. This rating easily withstands rain showers, handwashing, kitchen splashes, and light recreational swimming.
