Casio Edifice EFV-640D-1AV UDF

The Casio Edifice EFV-640D-1AV brings a strong, contemporary look to the EDIFICE Standard Chronograph collection. Its standout feature is the octagonal bezel, which gives the watch a dynamic and sporty character while maintaining the refined appearance expected from an EDIFICE timepiece. The watch has a 44.3 mm wide stainless steel case with a thickness of 10.8 mm and weighs approximately 136 g. Its stainless steel bracelet is secured with a convenient one-touch 3-fold clasp, while the mineral glass provides protection for the dial. The integrated chronograph provides 1/10-second precision and can measure up to 59 minutes and 59.9 seconds. It supports elapsed-time, split-time, and first/second-place timing. The three sub-dials display the chronograph’s 1/10-second, minute, and second measurements, while a date display adds everyday practicality. With 100-meter water resistance, approximately 2 years of battery life from an SR920SW battery, and an accuracy of ±20 seconds per month, the EFV-640D-1AV is a versatile choice for everyday, business, and casual wear.
