Casio Edifice Standard Chronograph watch, steel, EFV-640D-1AVUEF
Stainless steel Casio Edifice Standard Chronograph wristwatch with a black dial and an octagonal bezel
The black sunray dial has three subdials and a date display, and the octagonal bezel has a seconds scale. The look is sporty but understated, and the 44.3 mm wide steel case works well as an everyday watch. The luminous coating makes the time easier to read in low light. Edifice is Casio's collection of metal-cased, motorsport-inspired watches.
The quartz movement runs on a battery. The chronograph measures time up to one hour with a precision of one tenth of a second. Water resistance of 100 m / 10 atm is enough for swimming, water sports and snorkeling, but not for scuba diving. The steel bracelet fits wrists of 150–205 mm.
