CASIO EDIFICE EFS-S520

The new CASIO EDIFICE EFS-S520 series stand out sapphire crystal, carbon dial and a sustainable energy supply.
The latest model of EDIFICE by CASIO features impressive high-quality materials combined with an environment-friendly and innovative solar technology that CASIO has named Tough Solar® due to its exceptional performance capacity.

The watch features tiny solar cells integrated inconspicuously in the dial that absorb solar energy and daylight to power the watch. Excess solar energy is stored in a battery that provides a dark power reserve of up to 24 months.

CASIO has been gradually advancing this technology for 35 years. In the early 1980s the solar cells were still visible on the dial. Now these extremely high-capacity cells are integrated in the dial and even respond to artificial light. This makes battery changes a thing of the past.

For the first time, the CASIO EDIFICE EFS-S520 features solar cells that are placed on a dial made of carbon fibre. The even fabric structure of this highly resilient material underscores the high-quality, athletic character of the chronograph.

The main dial has three ancillary dials: a 24-hour display at 3 o’clock, a small second hand with a battery display at 6 o’clock and a stopwatch at 9 o’clock. A useful battery display is also integrated at 6 o’clock, allowing the user to check the level at all times.

The watch is dynamic in design, in line with the EDIFICE brand motto ‘Speed & Intelligence’. The look and functions of the watch are inspired by motor racing, as can be seen in the striking stainless steel case, the detailed carbon dial with red highlights and the sporty bezel with black IP coating.

In the EFS-S520CBL, a black napped leather strap with red seams reminiscent of a sports seat in a racing car perfectly rounds off the sporty look of this light-operated watch.

The EFS-S520 is capable of handling somewhat rougher sports activities, too: the watch glass is made of scratch-resistant sapphire crystal.

The CASIO EDIFICE EDIFICE EFS-S520 series is available in stores from February 2018 at a recommended retail price starting at EUR 189.
