Casio Edifice EFR-505 Watches

A strict minimalistic chronograph with a laconic dial – for fans of classic simplicity and restrained design. Most hour markers are labeled with the appropriate numeric designations to improve readability – this makes it easier to navigate in the current time. Two additional windows are responsible for indicating the time of the stopwatch, and the third shows the time in 24-hour format. The case and bracelet are made of high-strength steel, and the mineral glass reliably protects the dial from damage. The hands and hour markers have a light-accumulative coating that glows in the dark.
