Premium Design

Blending minimalism with sporty retro aesthetics, the Casio F-91WF-3ADF modernizes the world’s most recognized digital watch shape. The subtle olive green color palette adds a neutral, Earth-toned touch that pairs effortlessly with modern casual, streetwear, and athletic attire. Designed to sit low and light on the wrist, its compact profile offers an understated look that never goes out of fashion.

Dial Features

The clear digital LCD display provides immediate, highly legible timekeeping at a single glance. It displays hours, minutes, seconds, pm indicator, date, and day of the week with crisp visibility. For effortless nighttime reading, a built-in micro-LED side light illuminates the screen whenever required, ensuring functional utility around the clock.

Case Features

Crafted from high-grade durable resin, the square case of the F-91WF-3ADF measures approximately 38.2mm x 35.2mm with an ultra-slim thickness of just 8.5mm. This lightweight resin housing protects the internal module against everyday bumps and impacts while remaining light enough to forget you are even wearing it.

Movement

At the core of the Casio F-91WF-3ADF is a precision-engineered Japanese quartz movement (Module 593). Renowned globally for extreme accuracy, it maintains reliable timekeeping within ±30 seconds per month. Powered by a long-lasting CR2016 lithium coin cell battery, this movement offers an incredible approximate battery life of up to 7 years under normal usage conditions.

Strap/Bracelet

The matching olive green resin strap offers flexibility, skin-friendly comfort, and resilience against moisture and sweat. Secured with a sturdy, adjustable pin buckle closure, the strap ensures a customized, stable fit for a wide range of wrist sizes.

Water Resistance

Built for standard daily utility, the Casio F-91WF-3ADF offers everyday water resistance suitable for daily wear. It effortlessly handles minor splashes, rain showers, and accidental hand-washing contact, making it a reliable companion for daily routines in Sri Lanka’s tropical climate.

Comfort

Weighing approximately 21 grams, this watch offers exceptional, weightless comfort all day long. Its low profile prevents catching on shirt sleeves or jacket cuffs, making it one of the most comfortable daily drivers ever produced.
