Casio EFV-640D-3AV

Slip on a classic with a colorful twist wearing the Casio Edifice EFV-640D-3AV. This sporty analog chronograph seamlessly blends high-performance timing with a refined, architectural edge. The standout visual attraction is its soft, yet vibrant sage-green dial, which breaks away from traditional dark watch faces to inject an incredibly fresh, contemporary aesthetic into your daily rotation.

The defining characteristic of this model is its beautifully geometric octagonal bezel. To achieve a striking play on light, the flat front surfaces are brushed to a fine hairline finish, while the angled sides feature high-polished mirror surfaces, providing a "handsome textural contrast" that elevates it to a true fashion statement.

Key Features

• Architectural Octagonal Bezel: Features an iconic eight-sided geometric profile with alternating brushed and mirror-polished facets that catch the light from every angle.
• Vibrant Sage Green Dial: Dressed in an eye-catching, pastel-tinted green hue that adds a unique "touch of extra style" while maintaining a highly professional look.
• Full Stainless Steel Construction: Built with a solid steel case and a matching link bracelet, giving the watch a premium, substantial presence on the wrist (136 g).
• 100-Meter Water Resistance: Engineered with a robust 10-bar depth rating, making it completely resilient against swimming, cold showering, snorkeling, and sudden downpours.
• 1/10-Second Chronograph: Equipped with an active three-dial stopwatch configuration capable of measuring split times, elapsed times, and 1-2 place finishes down to a fraction of a second.
• Slim Executive Profile: Despite its commanding 44.3 mm width, it stands at a remarkably thin 10.8 mm, allowing it to slide smoothly under crisp dress cuffs or jackets.
• One-Touch 3-Fold Clasp: Designed with an ergonomic metal deployment buckle that clicks shut securely and opens effortlessly with a quick squeeze of the side push-buttons.
