The Casio W-738H-3AV combines practical everyday functionality with a rugged, sporty design inspired by classic square-case digital watches. Finished in a versatile olive green colourway, this durable timepiece is designed for active lifestyles, work environments, outdoor adventures, and daily wear.

Additional features include dual time display, 1/100-second stopwatch, countdown timer, daily alarm, hourly time signal, and a full auto-calendar, making it an excellent all-round digital watch for everyday use.
The square resin case offers a comfortable mid-size profile that wears naturally on the wrist while maintaining a bold, sporty appearance. Lightweight at only 43 grams, it provides all-day comfort without sacrificing durabilit
