Description
The Casio Edifice EFS-S660PB-1AEF is a sporty men's chronograph that combines motorsport aesthetics with reliable solar technology. The compact stainless steel case with grey ion-plating and a black ion-plated bezel measures just 38.3 mm in diameter and 11.6 mm in height, delivering a slim profile suited to any occasion. The textured dial allows sufficient light through to ensure continuous solar operation, while the central seconds hand enables precise timekeeping to 1/20 of a second.
The sturdy resin strap accommodates wrist circumferences from 14.5 to 21.5 cm and ensures excellent wearing comfort. With water resistance to 10 bar, a scratch-resistant sapphire crystal with anti-reflective coating, and a tachymeter bezel, the EFS-S660PB-1AEF is a dependable companion for active men with an eye for speed and style. A date display and a stopwatch with lap time measurement complete the feature set.
