Casio Edifice Classic watch, steel, EFS-S660PB-1AEF
Gray Casio Edifice Classic Watch with Solar Movement, Chronograph and Black Tachymeter Bezel
A red timing hand sweeps across the black textured dial, which is framed by a black tachymeter bezel. The Casio Edifice Classic EFS-S660PB-1AEF is a men's watch whose gray steel case and vertically grooved black polyurethane strap give it a sporty look. Edifice is Casio's collection of metal-cased watches inspired by motorsport.
The chronograph measures time to 1/20 of a second, and the tachymeter scale on the bezel can be used to estimate average speed. The solar cell charges the watch from light, so you never need to replace the battery. The crystal is sapphire crystal. Water resistance is 100 m / 10 atm, so the watch is suitable for swimming and snorkeling, but not for scuba diving. The case is 38.3 mm wide and 11.6 mm thick, and the watch weighs 71 g.
