Dial Features

The center of attention is the striking multi-layered black dial, designed to deliver optimal legibility and high-end visual appeal:

• Sub-dials for Chronograph Functionality: Features dedicated sub-dials for stopwatch minutes, stopwatch seconds, and 24-hour time display.

• Luminous Hands and Markers: Applied hour markers and central hands are coated with luminous material, ensuring effortless time reading in low-light environments.

• Date Display Window: Conveniently positioned date indicator for quick daily reference.

• Textured Background: Subtly detailed dial surface adds depth and visual texture beneath the protective glass layer.

Case Features

Constructed with a robust stainless steel bezel and case back, the EFV-640D-1AVUDF guarantees long-lasting structural integrity:

• Mineral Glass Protection: Hardened mineral crystal covers the dial, providing excellent scratch resistance against accidental bumps.

• Screw Lock Back: A solid screw-down case back enhances water resistance and protects the high-precision internal movement from moisture and dust particles.

• Ergonomic Pushers: Precision-machined crown and chronograph push buttons provide tactile feedback when activating stopwatch functions.

Movement

At the heart of the Casio Edifice EFV-640D-1AVUDF is a precise Japanese quartz movement. Renowned worldwide for unyielding precision, this movement maintains an accuracy within ±20 seconds per month. Powered by a standard SR920SW battery, it ensures steady, hassle-free operation for approximately 2 years without requiring manual winding or frequent adjustments.

Strap/Bracelet

The watch comes equipped with a solid stainless steel bracelet featuring a 3-fold clasp with a single-touch push-button release:

• Secure Attachment: The double-locking mechanism prevents accidental opening during daily movement.

• Corrosion Resistant: High-quality steel construction protects against sweat and atmospheric humidity common in Sri Lanka.

• Customizable Fit: Removable links allow easy resizing for maximum wrist comfort.

• Safe for swimming, snorkeling, and rain exposure.

• Ideal for everyday active lifestyles without worrying about water damage.

• Note: Crown and pushers should not be operated underwater.

Comfort

Despite its solid stainless steel construction and feature-rich dial layout, the watch offers an ergonomic fit tailored for all-day wear.
