Casio GPR Runner Watch GPR-100E

A pace checker feature shows the difference between your current time and distance, and target values. Up to 50 run records can be stored in memory. The watch even uses GPS time data, it receives to calibrate the settings of your Home Time zone and World Time Mode times automatically. All of this makes the GPR-100 the perfect too for runner training management, as well as for cycling, Nordic walking, and just about other outdoor sport imaginable.
