Reception radio waves: JJY, frequency: 40kHz / 60kHz (model compatible with both Fukushima and Kyushu stations) < North America > Received radio waves: WWVB, frequency: 60 kHz Received radio waves: MSF/DCF77, frequency: 60 kHz / 77.5 kHz Received radio waves: BPC, frequency: 68.5 kHz *Home time settings can be received in cities Once set, you will receive stations tailored to your city. Please note that the time difference is set depending on the selected city. - Sensor function details
- *The altimeter is a relative altimeter that converts changes in atmospheric pressure into altitude. If the atmospheric pressure changes due to weather conditions, the altitude of the measured value will also change. * When measuring the outside temperature, remove the watch from your wrist to prevent it from being affected by body temperature, sweat (water droplets), direct sunlight, etc.
