Item Detail
Battery CTL1616 (Storage battery)
Note: Use CTL1616 only. Other storage battery or CR1616 can cause damage to the
watch.
Battery life Approx. 8 months
Current consumption 1.32 μA maximum
See page 16
Alarm system Piezo plate on Cover/Back
Accuracy ± 15 sec./month
Accuracy setting system Theoretical regulation
Accuracy checking See page 17
Functions • Timekeeping: Hour, minutes, seconds, p.m. (P), year, month, day, day of the week,
Time format: 12-hour and 24-hour
Calendar system: Full Auto-calendar pre-programmed from the year 2000 to 2099
• Time Calibration Signal Reception:
Auto receive 6 times a day (5 times a day for the Chinese calibration signal) ; Remaining auto receives cancelled as
soon as one is successful; Manual receive; Receive Mode
Receivable Time Calibration Signals:
Mainflingen, Germany (Call Sign: DCF77, Frequency: 77.5 kHz); Anthorn, England (Call Sign: MSF, Frequency: 60.0
kHz); Fort Collins, Colorado, the United States (Call Sign: WWVB, Frequency: 60.0 kHz); Fukushima, Japan (Call
Sign: JJY, Frequency: 40.0 kHz); Fukuoka/Saga, Japan (Call Sign: JJY, Frequency: 60.0 kHz); Shangqiu City, Henan
Province, China (Call Sign: BPC, Frequency: 68.5 kHz)
• 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 (–32,800 to 32,800 ft.)
Negative values can be caused by readings produced based on a reference altitude or due to atmospheric condi-
tions.
Display unit: 1 m (5 ft.)
Altitude Memory Data:
Manual save records: 40 (altitude, date, time)
Auto save values: High altitude (with month, day, time of reading), low altitude (with month, day, time of reading),
cumulative ascent (with month, day, time of first reading), cumulative descent (with month, day, time of first
reading)
Other: Reference altitude setting; Altitude graph; Altitude differential; Altitude auto measurement method (0’05 or 2’00)
• Digital Compass: 60 seconds continuous measurement; Angle value 0° to 359°; Four direction pointers; Calibration
(bidirectional, northerly); Magnetic declination correction; Bearing Memory
• Barometer:
Measurement and display range: 260 to 1,100 hPa (7.65 to 32.45 inHg)
Display unit: 1 hPa (0.05 inHg)
Measurement timing: Periodic atmospheric pressure measurement (at two hour intervals); Real time measurement,
Barometric pressure sensor calibration, Barometric pressure graph, Atmospheric pressure differential graphic, Atmo-
spheric pressure tendency information
• Thermometer:
Measurement and display range: –10.0 to 60.0°C (14.0 to 140.0°F)
Display unit: 0.1°C (0.2°F)
Real time measurement, Temperature sensor calibration
• Bearing Sensor Precision: Direction: Within ±10°
Values are guaranteed for a temperature range of –10°C to 60°C (14.0 to 140.0°F)
North pointer: Within ±2 digital segments
• Temperature Sensor Precision:
±2°C (±3.6°F) in range of –10°C to 60°C (14.0 to 140.0°F)
• Pressure Sensor Precision:

5. REPLACEMENT OF BATTERY: MODULE QW-3410
5-1. OPEN DISPLAY
This model is equipped with EEPROM. When the back cover is open, a message “OPEN” is displayed
on the LCD.
The watch is in the Timekeeping mode. Returns to the usual display when the cover is closed.
5-2. AC (ALL CLEAR)
Be sure to perform AC (All Clear) after a battery is replaced.
Unless AC is performed, the memory(s) and/or counter(s) may not be initialized and cause malfunc-
tions.
1) Touch the AC contact and the CIRCUIT SUPPORTER 3414 with metallic tweezers.
The contact should be made for about two seconds.
2) Close the back cover.
3) Press any button except Eto go to the Timekeeping mode.
Without pressing buttons, it takes approximately one minute to automatically go to the
Timekeeping mode.
* When removing the back cover, do not misplace the spring/coils.

6. DISASSEMBLY AND REASSEMBLY: MODULE QW-3410
Note: The pressure sensor may be replaced separately.
The temperature sensor is mounted on the flexible board of the pressure sensor;
therefore, replacing the pressure sensor may repair some temperature measurement
failures.
The O ring for the back cover has 6H, and 12H sides.
Be careful to place the O ring in the right direction.
6-1. REMOVING THE MODULE
1) When removing the back cover, do not misplace the spring/coils.
