Smartphone link with accelerometer improves the accuracy* of distance measurements.

Distance Measurement Function

Distance Measurement Function

Smartphone GPS function adjusts distance measured by the accelerometer for more accurate* distance measurement. After adjustment, it is possible to measure distance using only the watch.

  • * Compared to the conventional Casio model that measures distance using only an accelerometer. This function depends on the accuracy of the smartphone GPS.

Size of Case / Total Weight

  • * The heart rate monitor displays the estimated heart rate based on the pulse measured by the sensor on the back of the watch (back cover). The heart rate data displayed by the watch is for reference only, and accuracy is not guaranteed.
  • * The heart rate measurement function of this watch is for recreational use only and cannot be used for any medical purpose.
  • * When without GPS signal reception or without a smartphone link, the watch operates with normal quartz accuracy (average monthly difference: ±15 seconds).
  • * The altimeter is a relative altimeter that converts changes in pressure to altitude. When atmospheric pressure changes due to weather conditions, the measured altitude value also changes.
  • * For outdoor temperature measurements, remove watch from wrist and make sure that it is not affected by body temperature, sweat (water droplets) or direct sunlight.
  • * The GBD-100 is approved under the Japan Radio Act.
  • * The smartphone connectivity depends on the specifications of the mobile phone itself as well as the services provided by the telecommunications carrier in the country of use, and results will therefore vary.
