Casio Edifice EFV-640D-3AVUEF
Product Information
About the watch
The green dial gives the classic chronograph layout a softer colour scheme without losing its sporty direction. Three sub-dials create an instrument-like feel for the front, allowing the central hands to maintain a clear visual focus. The subtly coloured dial contrasts with the surrounding silver tones, giving the 3AV version its own identity within the model family. It's an analog Edifice where colour and function share the spotlight.
Material & fit
The case measures 47 mm in length, 44.3 mm in width, and 10.8 mm in thickness. Stainless steel is used for the case, bezel, and bracelet, and the total weight is 136 grams. The flat front of the octagonal bezel has a finely brushed finish, while the sides are mirror-polished. Mineral glass protects the dial. The steel bracelet closes with a one-touch triple-fold clasp. The combination of the brushed front surface and the polished side sections makes the bezel's geometry clearer from multiple angles. The surface treatments thus divide the bezel into a matte front plane and a shinier outer edge.
