When barometric pressure changes due to weather conditions, the measured altitude value also changes. * When measuring the outside temperature, remove the watch from your wrist to avoid the effects of body heat, sweat (water droplets), direct sunlight, etc. "IMPORTANT" Customs and taxes: Your country of residence may apply additional customs duties and import taxes.
