Casio to Release New PRO TREK Smart That Supports Personalized Pacing in Exercise


Heart Rate Monitor Enables Users to Pace Themselves when Road or Trail Running


Casio Computer Co., Ltd. announced the release of a new addition PRO TREK Smart series for outdoor enthusiasts. The new WSD-F21HR, to be released September 13, 2019, is an outstanding smartwatch for efficient, effective fitness training, as well as mountain climbing and trekking. The heart rate monitor is great for pace management during activities such as road running, trail running and cycling.

Casio entered the smartwatch market in 2016 and released the WSD-F20 in 2017. Featuring GPS technology and offline maps, this and subsequent models allowed users to easily check their current location from their wrist, even in locations without cell phone service, and they have been especially popular.

The new WSD-F21HR offers a new heart rate monitor together with the wearable map technology, enabling wearers to continually check their physical condition, or navigate unfamiliar routes. Running and Trail Running menus have been added to the Activity app, which displays measurement data in real time. The user can optimize the data displayed by choosing three types of information such as heart rate, pace, and distance*1 to display on the watch. Furthermore, because up to four screens can be set, the user can easily switch between

them and check the desired information during the activity.
*1: The information that can be displayed includes Heart rate and zone / Heart rate / Heart rate graph/ Total time / Running time

/Expected time / Goal ETA / Lap / Average lap / Pace / Average pace / Maximum pace / Total distance / Distance remaining to goal / Speed / Average speed / Maximum speed / Speed graph / calories consumed /Barometer / Barometer graph / Altitude / Altitude change graph / Target altitude / Altitude remaining to goal / Elevation gain / Elevation loss / Current time / Battery level

Certain types of information can only be shown in the upper, middle, or lower parts of the display.

In addition, it comes with a new Heart Rate watch face. Using an accelerometer, the WSD- F21HR automatically switches to the heart rate monitor screen when motion is detected. The heart rate information is expressed as five heart rate zones,*2 allowing the user to see this data at a glance.

*2: By setting the maximum and resting heart rates, current fitness and training results can be shown as five levels. The targetexercise intensity can be checked with the heart rate zone screen, allowing the user to determine the ideal heart rate for the target training, or the user’s current fitness level.

As with other PRO TREK Smart models, the new WSD-F21HR can use Google App services, the trekking app ViewRanger, the cycling app BIKEMAP, the running app STRAVA, and other outdoor sports apps compatible with Wear OS by Google. The WSD-F21HR is a wrist device for all kinds of activities.
