Barometer
Measurement and display range: 260 to 1,100 hPa/mb (or 7.65 to 32.45 inHg)
Display unit: 1 hPa/mb (or 0.05 inHg) 1hPa = 1mb
Measurement Timing: Daily from midnight, at two hour intervals (12 times per day); every five second in the barometer/thermometer mode
Other: Calibration; manual measurement (button operation); barometer pressure graph

Thermometer
Measurement and display range: -10.0 to 60.0C (or 14.0 to 140.0F)
Display unit: 0.1C (or 0.2F)
Measurement Timing: Every five seconds for the first three minutes after entering the Barometer / Thermometer Mode
Other: Calibration; manual measurement (button operation)

Altimeter
Measurement range: -700 to 10,000 m (-2,300 to 32,800 ft) without reference altitude
Display range: -10,000 to 10,000 m (or -32,800 to 32,800 ft)
Negative values can be caused by readings produced based on a reference altitude or due to atmospheric conditions
Display unit: 5 m (or 20 ft.)
Other: Reference altitude setting; altitude graph; altitude differentia; altitude measurement type

Bearing Sensor Precision
Direction: Within 10
Values are guaranteed for a temperature range of -10C to 40C (14F to 104F)
North Pointer: Within 2 digital segments

Pressure Sensor Precision
Values are guaranteed for a temperature range of -10C to 40C (14F to 104F)
Precision is lessened by strong impact to either the watch or the sensor, and by temperature extremes
