Product information

Introducing the Casio ProTrek Smart WSD-F20X...

Like its base model, the WSD-F20X features low-power GPS and color map functionality that can be used offline. By downloading maps in advance, you can easily check your current location using only the watch. When skiing or snowboarding, the Snow mode of the Activity app lets you check out the course and maximum speed of each run, letting you make the most of every trip down the hill.

A newly-designed watch face called "Place" has been added to the lineup of interchangeable watch faces. When the watch is used to select an event with a location from your Google Calendar, a map of the destination will appear in the background of the analog-style watch display. Of course, the current location can also be shown. In addition, the round windows at the 12 and 6 o’clock positions represent complications made possible by Android Wear devices.

Another useful feature is the customisability of the information appearing on the watch face, such as altitude, atmospheric pressure, and battery level, as well as data from Google or third-party apps. The "Place" watch face is scheduled for release at the same time as the WSD-F20X, and it can also be installed on the existing model, the WSD-F20.
