Description
The Casio Edifice EFV-620L-1AVUDF (also referenced as EFV-620L-1AV / EFV-620L) is a bold, high-precision Japanese quartz chronograph designed for men by Casio under the speed-and-intelligence-inspired Edifice series. Recognized among watch collectors and daily-wear enthusiasts by its series nicknames—the "Classic Sports Chronograph" or "Black Dial Leather Chronograph"—this 50.5mm timepiece pairs a solid stainless steel case with a multi-layered matte black dial, a black ion-plated bezel ring, a calendar date window at 3 o'clock, a screw-lock back plate, and a genuine black leather strap. Designed for modern gentlemen who appreciate athletic motorsport styling, functional timing capability, and versatile leather strap comfort, it transitions effortlessly from business meetings to casual weekend wear. The defining visual highlight of this EFV-620L-1AVUDF reference is its multi-dimensional black dial face framed by a sporty black ion-plated bezel. Set beneath a protective mineral crystal, the dial features bold 3D hour markers with luminous coating for low-light legibility, three detailed sub-dials for chronograph timing, and a framed calendar date window positioned cleanly at 3 o'clock. The combination of deep black, stainless steel, and refined genuine leather delivers a dynamic, high-contrast aesthetic on the wrist. Beneath its athletic exterior, the watch is driven by a high-accuracy Japanese Quartz Movement powered by an SR920SW silver oxide battery, providing a reliable battery life of approximately 3 years with a timekeeping precision within ±20 seconds per month. The integrated 1/10-second chronograph offers measuring capacities up to 59 minutes and 59.9 seconds with dedicated timing modes for elapsed time, split time, and 1st-2nd place finishes. The bold round housing measures 50.5mm in case width (55.0mm lug-to-lug) with a profile thickness of 12.4mm and a comfortable weight of approximately 90 grams. Dial protection is provided by a durable, scratch-resistant mineral crystal. Engineered for everyday durability and water activities, the solid stainless steel case incorporates a screw-lock back plate and protective crown guards, achieving a certified 100-meter (10 bar / 330 ft) water resistance rating to safeguard against daily rain, splashes, showering, and swimming. The timepiece comes completed on a genuine black leather strap, fitted with a stainless steel pin buckle clasp for a secure, customized fit.
