Finnish Family-Owned Business Since 1972Casio Edifice Classic watch with black dial, blue chronograph hand and steel case
The Edifice Classic EFS-S660D-1AEF is a solar-powered chronograph with a blue timing hand that stands out against the black dial. The dial surface is textured, and the tachymeter scale on the black bezel can be used to calculate average speed. The silver-coloured case is angular, the bracelet is made of the same stainless steel, and the date display is at three o'clock. The case is 38.3 mm wide and 11.6 mm thick. The Casio Edifice collection is a series of metal-cased watches inspired by motorsport.
The solar movement charges the watch from light, and on a full charge the watch runs for about 5 months without light. The chronograph measures to 1/20 of a second, and the crystal is sapphire. Water resistance is 100 m / 10 atm, so the watch withstands swimming, water sports and snorkeling but is not suitable for scuba diving. The bracelet fits wrists of 150–205 mm.
