Model No. BJ2XXX

Cal. No. B74❈

This watch is an analog solar powered diver's

watch into which an electronic depth meter function

and chronograph function are built. The solar power

generation function transforms solar energy to

electrical energy to run the watch.

• Since solar energy is used as the power source of

this watch, it has no need of regular replacement

of the battery unlike the general diver’s watches

using the mercury cell, etc. (Solar power function)

• The built-in depth meter function automatically

measures the depth in diving with the watch worn

on the wrist. (Depth meter function)

• The maximum depth in diving is automatically

memorised. (Maximum depth memorising

function)

• The chronograph function measures the time in

units of one second for 50 minutes at maximum.

Safety precautions

(Instructions to be followed at all times)

In order to prevent injury to yourself or other

persons or damage to property, this manual gives

instructions which you should strictly follow as

described below

■ Injury and/or damage which might be caused by

using the watch improperly or neglecting any of

the instructions or precautions in this manual are

classified using the following symbols.

■ The instructions for safe operation are classified

using the following symbols.

(The following are just examples of symbols.)

WARNING

• Diving is one of the sports involving many risks.

When using this watch for diving, carefully read

this manual and follow the instructions with good

understanding of the proper way to use it.

• Diving with this watch must be limited to

recreational diving (diving without decompression).

Don’t use this watch for decompression diving,

saturated diving or diving in a high altitude. The

depth meter function of this watch works normally

in seawater with temperatures of +10˚C to +40˚C

(50˚F to 104˚F), however, depth indication is

incorrect in water other than seawater (specific

gravity: 1.025).

• Rapid and sharp change of the atmosphere and/or

seawater temperature occasionally affects the

indication and performance of the watch.

Therefore, it is recommended that this watch be

used together with another depth gauge. Read the

indication of this watch as a rough guideline.

• Even recreational diving involves many risks.

Before using this watch as an auxiliary instrument

for diving, be sure you receive right training in

scuba diving by a qualified instructor in order to

acquire experience and technique necessary for

safe diving as well as to master the proper way to

handle and operate this watch.

Any repair of this product should be conducted at

a Citizen Service Centre. For repair and

inspection please contact the place of purchase

or contact a Citizen Service Centre directly.

• Before using this watch,

carefully read this instruction

manual for safe and correct use.

• After reading this manual, keep

it at hand for future reference.

Since the depth meter function of this watch is

not approved as an official depth gauge, be sure

to use this function as an auxiliary means to know

the approximate depth.

Can cause serious injury or death.

Can or will cause minor or moderate injury or damage.

Warning or caution symbol followed by instructions for safe operation and/or precautions that you should take.

1. BEFORE USING “Battery” means a secondary battery (rechargeable battery) in this manual. Before using, make sure the watch is sufficiently charged by exposing it to the light. A secondary battery is used in this watch to store electrical energy. If the battery is fully charged once, the watch will continue running for about two months. When the watch is used for diving (about two hours a week), it will run for about one month (until NG is indicated).

• After confirming that the crown is screwed down tightly, wash out seawater, mud, sand, etc. sticking to the watch, with fresh water. Then, wipe off water and moisture with a dry soft cloth. • Neither remove the sensor cover nor pick at it with a sharp-point in order to remove particles of dust, etc., collected in the sensor. If the sensor part is packed with dust, etc., wash it out with fresh water.

. WARNING FUNCTIONS OF THIS SOLAR POWERED WATCH With decline of the battery power of this watch, its warning function is activated to change the indication. Charge level indication The function hand indicates the charge level as follows (LV.1, LV.2, and NG) to let the user know whether the watch can be used for diving or not.In the diving mode, consumption of battery power is considerably increased because the pressure sensor and water sensor are actuated.
PAGE 5
Stop warning function Stop warning indication – Mode hand: “0” position, Function hand: “0” position If the watch is left in the insufficient charge warning indication for two days, both the mode hand and function hand will move to “0” position respectively. If the watch falls into this condition, it indicates that the watch has stopped operation completely. (Stop warning indication) * All functions of the watch are inactivated in this indication.
PAGE 6
7. SWITCHING BETWEEN MODES • Each time button A is pressed for two seconds, the mode is switched from the time mode to the chronograph mode and vice versa. • If the water sensor gets wet while the water is in time mode, the mode is switched over to the diving mode. However, this mode shift is not performed when the function hand indicates “NG” on the charge level index.
PAGE 7
9. DIVING MODE When the watch is immersed in the water, while it is set in the Time mode and the battery is charged enough for diving, the water sensor senses the water and switches the watch to Diving mode to measure the depth. In the Diving mode, the watch automatically memorises the maximum depth of the last dive and the user can recall it after the dive.

12. SETTING FUNCTION HAND AT “0” POSITION (1) Set the watch to the Time mode or Chronograph mode. (2) Press button A or B to set the function hand to the “0” position. (3) Press the crown into the normal position and turn it until it is tightly screwed against the case. * The aforementioned procedure is effectual only when the hand is located within 15 graduations before/after the “0” point. When the hand is located outside the adjustable range, correct the “0” position of the hand referring to “13.
PAGE 9
[No decompression limits] The range within which the diver can rise to the surface without rest for decompression is determined by the depth and elapsed time of the dive. The ranges are called “No Decompression Limits”. A table of “No Decompression Limits” compiled according to the U.S. Navy Diving Manual (1993 edition) is printed on the watchband of this watch (there are some models that have no print of the table on the watchband).

CAUTION – Note on the luminous dial • The luminous paint used for the dial of this watch is mainly made from light accumulating materials, which are harmless to the human body and the environment since it contains no toxic substances such as radioactive material. This luminous paint accumulates light of the sun and indoor lighting and emits light in a dark place. (For example, if the luminous dial is exposed to light of 500 lux or more for 10 minutes or longer, it will emit light for 3 to 5 hours.
