Dial Features

The focal point of the Casio Edifice EFV-640D-2AVUDF is its captivating sunray blue dial. Decorated with multi-dimensional sub-dials, the layout offers clear readability and high visual depth. Applied silver-tone hour markers and prominent hands are coated with Neobrite luminous material, ensuring effortless timekeeping even in low-light environments. A discrete date window situated between the 4 and 5 o'clock positions provides added daily convenience without cluttering the dial’s aesthetic harmony.

Case Features

Crafted from solid high-grade stainless steel, the case measures approximately 47mm in diameter and 10.8mm in thickness. The sturdy construction protects the internal movement from everyday impacts and vibration. Featuring a solid screw-lock back, the casing protects the internal mechanics against moisture and dust ingress, guaranteeing longevity and structural integrity over years of wear.

Movement

Inside the Casio Edifice EFV-640D-2AVUDF lies a highly reliable Japanese quartz movement known for exceptional accuracy within ±20 seconds per month. The movement powers a precise 1/10-second chronograph stopwatch capable of measuring elapsed time up to 59 minutes and 59.9 seconds. Whether timing daily activities or sports events, the tactile pushers provide responsive and accurate stop-start execution.

Strap / Bracelet

The watch comes fitted with a durable, multi-link stainless steel bracelet that seamlessly integrates into the case design. It features a secure one-touch 3-fold clasp with a push-button release mechanism, ensuring that the watch stays safely on your wrist throughout the day while offering effortless application and removal.
