E-80
Specifi cations
Accuracy at normal temperature:
± 15 seconds a month (with no signal calibration)
Timekeeping:
Hour, minutes (hand moves every 10 seconds), seconds, day, day of the week
Calendar system: Full Auto-calendar pre-programmed from the year 2000 to 2099
Other: Home City code (can be assigned one of 29 city codes and Coordinated Universal Time);
Daylight Saving Time (summer time) / Standard Time
Time Calibration Signal Reception:
Auto receive up to six times a day (5 times a day for the Chinese
calibration signal; Remaining auto receives cancelled as soon as one is successful); Manual
receive
Receivable Time Calibration Signals:
Mainfl ingen, Germany (Call Sign: DCF77, Frequency: 77.5 kHz); Anthorn, England (Call Sign:
MSF, Frequency: 60.0 kHz); Fukushima, Japan (Call Sign: JJY, Frequency: 40.0 kHz); Fukuoka/
Saga, Japan (Call Sign: JJY, Frequency: 60.0 kHz); Fort Collins, Colorado, the United States
(Call Sign: WWVB, Frequency: 60.0 kHz); Shangqiu City, Henan Province, China (Call Sign:
BPC, Frequency: 68.5 kHz)
Compass:
20 seconds continuous reading; North indication by hand; Calibration (bidirectional, northerly);
Manual reading
Altimeter:
Measurement range: –700 to 10,000 m (or –2,280 to 32,800 ft.) without reference altitude
Display range: –3,000 to 10,000m (or –9,840 to 32,800 ft.)
Negative values can be caused by readings produced based on a reference altitude or due to
atmospheric conditions.
Measurement unit: 10 m (or 40 ft.)
Other: Calibration; Manual reading
E-81
Barometer:
Measurement range: 260 to 1,100 hPa (or 7.7 to 32.5 inHg)
Display unit: 1 hPa (or 0.1 inHg)
Other: Calibration; Manual reading; Barometric pressure differential indicator
Thermometer:
Measurement range: –10.0 to 60°C (or 14 to 140°F)
Measurement unit: 0.1°C (or 1°F)
Other: Calibration; Manual reading
Bearing Sensor Precision:
Direction: Within ±12°
Values are guaranteed for a temperature range of –10°C to 40°C (14°F to 104°F).

• Values are guaranteed for a temperature range of –10°C to 40°C (14°F to 104°F).
• Precision is lessened by strong impact to either the watch or the sensor, and by temperature extremes.
Temperature Sensor Precision:
±2°C (±3.6°F) in range of –10°C to 60°C (14°F to 140°F)
Alarm:
Daily alarm

Measuring capacity: 11:59' 59"
Measuring modes: Elapsed time
E-83
Illumination:
LED (light-emitting diode); Selectable illumination duration; Auto Light Switch (Full Auto LED
Light operates only in the dark)
Other:
Power Saving function; Low battery alert (second hand jumping at 2-second intervals); Auto hand
position adjustment
Power Supply:
Solar panel and one rechargeable battery
Approximate battery operating time: 7 months (from full charge to Level 3) under the following
conditions:
Alarm: 10 seconds/day
Light: 1.5 seconds (one operation)/day
Second hand operation: 18 hours/day
Time calibration receive: 4 minutes/day
Direction reading: 20 times/month (20 seconds continuous reading)
Readings using the barometric pressure differential indicator: 12 times/day
Climbs: Once (30 altituded readings)/month
Frequent use of illumination runs down the battery. Particular care is required when using the auto
light switch (page E-71).
