Main watch hour hand

Sub watch hour hand

(A) Button

Main watch second hand

KM. 13

Crown Date hand
*The sub-watch is synchronous with the main watch. *The day hand indicates the date of the main watch.
3. Adjusting the main watch
(1) When the second hand is at 0 second, pull the crown out to the position where you can adjust the time. (2) Turn the crown to adjust the main watch. It is at 0:00 am when the date increments. Don't mistake am for pm when adjusting the time. To adjust the time more accurately, it will be convenient to advance the minute hand 4-5 minutes ahead of the right value and turn it back. (3) After adjusting the time in reference to a time signal, return the crown it the normal position.

4. Adjusting the date

* The day hand indicates the date of the main watch. (1) Pull the crown out to the position where you can adjust the date. (2) Turn the crown to adjust the date. Turning the crwon once to the left will increment the date value. Turning it to the right does not work. The date varies in a period of 31 days. When the month ends at the 30th or earlier, you have to adjust the date at the first of the next month manually. Don't adjust the date in between 7:00 pm and 1:00 am because the date might not increment on the next day. Move the hand and adjust the date, avoiding that time zone. After adjustment, adjust the main watch again.

5. Adjusting the sub-watch (correcting time difference)
*You can adjust the time in units of hour in reference to the main watch. (1) Press the (A)-button once and the hour hand of the sub-watch goes back by an hour (counterclockwise). Press the (A)-button as many times as needed to correct time difference in reference to the main watch.
(Example) To adjust the sub-watch to the time at London when the main watch reads 10:10 am at Tokyo. The time difference between Tokyo and London is -9 hours. When it is 10:10 am at Tokyo, the time at London is 1:10 am. To correct the time difference: (2) Press the (A)-button nine times to move the hour hand of the sub-watch 9 hours back to 1 o'clock.

6. Using the Register Ring
The bezel design may vary depending on the model. [Calculation function] Note the following points when using this function. Use the calculation function of this watch only as a guide.These scales do not indicate the position of the decimal point.

Speed index

Outer scale (distance scale) Inner scale (Time acale)
1) Time required Example: Obtain the time required fo the fight of an aircraft at 180 knots for 450 nautical miles. Answer. Align 18 on the outer scale with the SPEED INDEX (L) on the inner scale. Then, 45 on the outer scale corresponds to 2:30 on the inner scale (time scale). Thus, the time required for the flight is 2 hours and 30 minutes. 2) Knots (air speed) Example: Obtain the knots (air speed) for 240 nautical miles with a flight time of 1 hour and 20 minutes.
A. Navigational calculation
Answer. Align 24 on the outer scale with 1:20 on the inner scale (time scale). Then, the SPEED INDEX (L) on the inner scale corresponds to 18 on the outer scale. Thus, the air speed for the flight is 180 knots. 3) Flight diatance Example: Obtain the air distance when the air speed is 210 knots and the flight time is 40 minutes. Answer. Align 21 on the outer scale with the SPEED INDEX (L) on the inner scale. then, 40 on the inner scale corresponds to 14 on the outer scale. Thus, the air distance of the flight is 140 nautical miles. 4) Rate of fuel consumption Example: Obtain the rate of fuel consumption (gallons / hour) when the flight time is 30 minutes and the fuel consumption is 120 gallons. Answer. Align 12 on the outer scale with 30 on the inner scale. Then, the SPEED INDEX (L) on the inner scale corresponds to 24 on the outer scale. Thus, the fuel consumption is 240 gallons per hour. 5) Fuel consumption Example: Obtain the fuel consumption required for a flight when the vate of fuel consumption is 250 gallons per hour and the flight time is 6 hours.
Align 25 on the outer scale with the SPEED INDEX (L) on the inner scale. Then, 6:00 on the inner scale (time scale) corresponds to 15 on the outer scale. Thus, the fuel consumption is 1,500 gallons. 6) Estimated flight time Example: Obtain the estimated flight time when the vate of fuel consumption is 220 gallons per hour and the aircraft has 550 gallons of fuel. Answer. Align 22 on the outer scale with the SPEED INDEX (L) on the inner scale. Then, 55 on the outer scale corresponds to 2:30 on the inner scale (time scale), Thus, the estimated flight time is 2 hours and 30 minutes. 7) Difference in altitude The difference in altitude can be obtained from the rate of descent and the descent time. Example: Obtain the difference in altitude when an aircraft continues descending for 23 minutes at a rate of 250 feet per minute. Answer. Align 25 on the outer scale with 10 on the inner scale. Then, 23 on the inner scale corresponds to 57.5 on the outer scale. Thus, the difference in altitude is 5,750 feet.

Answer.

8) Rate of climb (or descent) The rate of climb (or descent) can be obtained from the time required to reach an altitude. Example: Obtain the rate of climb when an aircraft reaches an altitude of 7,500 feet after climbing for 16 minutes. Answer. Align 75 on the outer scale with 16 on the inner scale. Then, 10 on the inner scale correspons to 47 on the outer scale. Thus, the rate of climb is 470 per minute. 9) Time of climb (or descent) The time required for climb can be obtained from the altitude to be reached and the rate of climb (or descent). Example: Obtain the time of climb when an aircraft is to climb to 6,300 feet at a rate of 550 feet per minute. Answer. Align 55 on the outer scale with 10 on the inner scale. Then, 63 on the outer scale corresponds to 11.5 on the inner scale. thus, the time of climb is 11 minutes and 30 seconds. 10) Conversion Example: Convert 30 statuts miles into nautical miles and kilometers. Operation: Align 30 on the outer scale with STAT (L) on the inner scale. Then, NAUT (L) on the inner scale corresponds to 26 nautical miles on the outer scale, and 12 km (s) on the inner scale corresponds to 48.2 km on the outer scale. 13
B. General Calculation Functions
1) Multiplication Example: Operation: Align 20 on the outer scale with 10 on the inner scale. Then, 15 on the inner scale corresponds to 30 on the outer scale. Take into account the position of the decimal point and add one zero to obtain 300. Note that with the scales of this watch, the position of the decimal point cannot be obtained. 2) Division Example: 250 / 20 Operation: Align 25 on the outer scale with 20 on the inner scale. Then, 10 on the inner scale corresponds to 12.5 on the outer scale. Take into eccount the position of the decimal point to obtain 12.5. 3) Proportion Example: 30/20 = 60/x Operation: Align 30 on the outer scale with 20 on the inner scale. Then, 60 on the outer scale corresponds to 40 on the inner scale. At this point,the proportion for every value on the inner and outer scales is 30:20.
4) Square root Example: Square root of 225 Operation: Turn the outer scale showly and find a value that corresponds to both 22.5 on the outer scale and 10 on the inner scale. In this example, 22.5 on the outer scale corresponds to 15 on the inner scale, and 10 on the inner scale corresponds to 15 on the outer scale. Thus, the answer is 15.

If moisture has entered the watch, or if the inside of the crystal is fogged up and does not become clear within a day, immediately take the watch to your dealer or Citizen Service Center for repair. Leaving the watch in such a state will allow corrosion to form inside. If seawater enters the watch, place the watch in a box or plastic bag and immediately take it in for repair. Otherwise, pressure inside the watch will increase, and parts (crystal, crown, buttons, etc.) may come off.
CAUTION: Keep your watch clean.
Dust and dirt tend to be deposited in gaps in the back of the case or band. Deposited dust and dirt may cause corrosion and soil your clothing. Clean the watch occasionally.

CAUTION

Do NOT operate the crown or button with wet fingers or when the watch is wet. Water may enter the watch and compromise water-resistance. If the watch is used in seawater, rinse with fresh water afterward and wipe with a dry cloth.

Cleaning the Watch

Use a soft cloth to wipe off dirt, perspiration and water from the case and crystal. Use a soft, dry cloth to wipe off perspiration and dirt from the leather band. To clean a metal, plastic, or rubber watchband, wash away dirt with mild soap and water. Use a soft brush to remove dust and dirt jammed in the gaps in the metal band. If your watch is not water-resistant, take it to your dealer.
NOTE: Avoid using solvents (thinner, benzine, etc.), as they may mar the finish.
WARNING: Handling of the battery
Keep the battery out of the reach of small children. If a child swallows the battery, contact a physician immediately.
CAUTION: Replacing the battery
For replacement of the battery, take your watch to your dealer or Citizen Service Center. Replace the battery as soon as possible if the service life of the battery has expired. Leaving a depleted battery in the watch may result in leakage, which can damage the watch severely.
CAUTION: Operating environment Use the watch within the operating-temperature range specified in the instruction manual. Using the watch where temperatures are outside the specified range, may result in deterioration of functions or even stoppage of the watch.
Do NOT use the watch in places where it is exposed to high temperature, such as in a sauna. Doing so may result in a skin burn. Do NOT leave the watch in a place where it is exposed to high temperature, such as the glove compartment or dash-board of a car. Doing so may result in deterioration of the watch, such as deformation of plastic parts. Do NOT place the watch close to a magnet. Timekeeping will become inaccurate if you place the watch close to magnetic health equipment such as a magnetic necklace or a magnetic latch of a refrigerator door or handbag clasp or the earphone of a mobile phone. If this has occurred, move the watch away from the magnet and reset the time. Do NOT place the watch close to household appliances that generate static electricity. Timekeeping may become inaccurate if the watch is exposed to strong static electricity, such as is emitted from a TV screen. Do NOT subject the watch to a strong shock such as dropping it onto a hard floor. Avoid using the watch in an environment where it may be exposed to chemicals or corrosive gases.
