Finnish Family-Owned Business Since 1972Black steel Casio Edifice watch with chronograph, solar-powered movement and sapphire crystal
A black dial resembling carbon fiber and three subdials give this Casio Edifice watch a sporty look. The timing subdials, the date display at 4 o'clock and the red hand stand out clearly against the black dial. Luminous hands and indexes help you read the time in dim light, and the sapphire crystal has an anti-reflective coating.
The case and bracelet are black stainless steel. The case is 44.5 mm wide and 13 mm thick, and the bracelet fits a 150–205 mm wrist. The watch weighs 118 grams. Solar cells charge the watch with light, and when fully charged, the watch keeps running in normal use for up to five months. Water resistance of 100 m / 10 atm is enough for swimming, water sports and snorkeling, but not for scuba diving. Edifice is a series of Casio metal-cased watches inspired by motorsport.
