CASIO to Release PRO TREK Smart for the Outdoors in Limited Edition Color
Deep White Color Scheme Inspired by Crystalline Fluorite

Norderstedt, January 10, 2018 – Casio Computer Co., Ltd. announced today a new addition to the PRO TREK Smart series of wrist devices for outdoor enthusiasts. The WSD-F20-WE features a fluorite white color scheme inspired by crystalline fluorite. A limited edition of just 1,500 watches will be released worldwide in March, 2018.

The WSD-F20-WE is a limited-edition color model of the WSD-F20 series, featuring white as a base color to provide an accent to colorful outdoor wear. The fluorite white scheme is inspired by the color of crystalline fluorite, which is sometimes used as a raw material in outdoor wear. The white color features a clear-coat to give a deep multilayer finish with crystalline-like depth.

CASIO is also releasing a new watch face called "Journey" that makes travel even more fun. Journey shows a map of the current location in the background of the analog-style watch display. When the user saves events with locations to Google Calendar, the watch displays up to three upcoming events and a map of the next scheduled destination. Users can save destinations beforehand from an itinerary, such as outdoor destinations or sightseeing spots, so that they always have a view of the next destination to look forward to and a map to guide them. Journey can also be installed on WSD-F20/F20S/F20X models.

The WSD-F20-WE is a limited-edition color model featuring white to give an accent to colorful outdoor wear, as well as a useful watch face that displays events in order to make trips and being outdoors even more fun.
