When barometric pressure changes due to weather conditions, the measured altitude value will also change. *When measuring the outside temperature, remove the watch from your wrist to avoid the effects of body heat, sweat (water droplets), direct sunlight, etc. Accuracy: ±15 seconds Compass Bezel LED: White Band Fitting Size: 145–215 mm First Link Width: 23mm Crystal Material: Inorganic Glass Case Material: Resin Case Size: 54.7 × 51.7mm Case Thickness: 15.1mm Band Material: DuraSoft Band Band Clasp Type: Buckle Wrist Circumference (Max): 21.5cm Dial Color: Black Weight: 60g
