Product Details
Description
The Casio EFV-640D-3AVUEF is a sporty yet elegant men's watch from the Edifice collection. The octagonal stainless steel case features a hairline-polished front surface and mirror-polished sides, creating a striking contrast that blends classic design with a modern sporting spirit. The vivid, softly toned dial adds a distinctive splash of colour to the wrist, making the EFV-640D-3AVUEF a true eye-catcher in everyday wear.
Mineral glass reliably protects the dial, while 100-metre water resistance (10 BAR) makes the watch a dependable companion for sport and leisure. A quartz movement ensures precise timekeeping with hours, minutes and seconds hands, plus three subdials for the chronograph function. The stainless steel bracelet with a single-push triple-fold clasp sits securely and comfortably on the wrist.
