Casio "PRO TREK Smart WSD-F21HR" released on 9 / 13! It seems to be good as a running watch with a heart rate measurement function

I'm a Casio girl. I'm a Tokyo stroller.
Casio Computer's new product “PRO TREK Smart” for outdoor device “PRO TREK Smart”WSD-F21HR"2019 9 May 13 will be available for sale on the day!

Equipped with heart rate measurement function

“WSD-F21HR” is equipped with a heart rate measurement function that is the first in the series. Combined with the map display function, it is easier to use for running and trail running, and boosts appropriate training by visualizing the distance you run while running, the distance to the goal, heart rate and pace. It seems to me.

The color is red and black 2. The price is 56,000 yen + tax.

The back of the board is equipped with an optical sensor that measures LED light on the wrist.

A new watch face “Heart Rate” is installed, and when the accelerometer detects movement, it automatically switches to the heart rate measurement screen, and the measured heart rate information is likely to be expressed in the heart rate zone at the 5 stage.


“Running” and “Trail running” are added as new activities, and up to 4 patterns such as pace, heart rate and distance can be registered in the display data.

Of course, like the conventional "PRO TREK Smart", it is waterproof to 5 pressure for outdoor use and toughness compliant with MIL specs (US military procurement standards established by the US Department of Defense).
