· Automatic daylight saving time adjustment; local time change; UTC direct recall
DIGITAL COMPASS
· 60-second continuous reading; 16 directions; angle value 0° to 359°; measuring unit: 1° (digital display)/6° hand; North indicated by the second hand: Compass calibration (bidirectional, figure-eight calibration, magnetic declination angle), automatic heading calibration.
ORIENTATION SENSOR ACCURACY
· Heading: Within ±10°.
· Values ​​are guaranteed for a temperature range of 10°C to 40°C (50°F to 104°F).
· North indicated by the second hand: Within ±2 digital segments.
BAROMETER
· Measuring range: 260 hPA to 1,100 hPA (7.65 inHg to 32.45 inHg).
· Display unit: 1 hPA (0.05 inHg).
· Barometric pressure graph; barometric pressure differential pointer (–10 to +10 hPa/–1 to +1 hPa); Barometric pressure change indicator
PRESSURE SENSOR ACCURACY
· Measurement accuracy: Within ±3 hPa (0.1 inHg) (Altimeter accuracy: Within ±75 m (246 ft)).
· Values ​​are guaranteed for a temperature range of –10°C to 40°C (14°F to 104°F).
· Accuracy decreases due to strong shocks applied to the watch or sensor, and extreme temperatures.
ALTIMETER
· Measurement range: -700 m to 10,000 m (-2,300 ft to 32,800 ft) without reference altitude.
· Display range: -3,000 to 10,000 m (-9,840 to 32,800 ft). Readings produced based on a reference altitude or due to atmospheric conditions may cause negative values.
· Display unit: 1 m (5 ft).
· Current altitude data: Every second for the first 3 minutes, then every 5 seconds for approximately 1 hour (0.05); every second for the first 3 minutes, then every 2 minutes for approximately 12 hours (2.00).
· Altitude memory data:
· Manually saved records: 14 (altitude, date, and time).
· Automatically saved values: A set of values ​​for high altitude and its reading date and time, low altitude and its reading date and time, total ascent and its storage start date and time, total descent and its storage start date and time.
· Activity log data: High altitude, low altitude, cumulative ascent, cumulative descent for up to 14 activities.
· Other: Reference altitude adjustment; Altitude difference (–100 to +100 m/–1,000 to +1,000 m); automatic altitude measurement range (0.05 or 2.00 m).
THERMOMETER
