English
To check the movement number
A case number—4 alphanumeric characters and 6 or
more alphanumeric characters—is engraved on the
case back. (Figure on the right)
The first 4 characters of the case number represent
the movement number of the watch. In the example
on the right, “ ” is the movement number.

PROHIBITED Do not use this watch while diving when...
• Do not use your watch while diving when the watch stops or exhibits any abnormal operation.
CAUTION Diving with the watch
• Persons using the diver’s watch are strongly recommended to receive proper instruction and
training pertaining to diving and observe those rules at all times.
• Please use this watch properly only after you fully understand the operating procedures and
cautions.
Using this watch other than as indicated in this instruction manual may result in failure of the
watch to function properly.
• Check the water-resistant indications on the watch face or the case back. Never dive beyond
the indicated depth.

CAUTION Before diving
• Check items below before diving
- Make sure that the watch is fully wound.
- Make sure that the watch is running correctly (check the movements of the time/calendar/
second hand)
- Make sure that the crown is pushed all the way in and locked in place.
- Make sure that the band is firmly anchored to the watch body.
- Make sure that there are no cracks or other damage to the watch band or the glass face.
- Make sure that the register ring rotates properly.
CAUTION During diving
• During diving, never operate the crown. Operating any of them in water may cause trouble
including deterioration of water resistance.
• Be careful not to hit the watch against hard objects such as equipment or rocks.
CAUTION After diving
• After making sure that the crown is locked in place, make sure the watch is free of seawater,
mud and sand using fresh water. Wipe completely with a dry cloth.

Characteristics of Mechanical watches
About time accuracy of mechanical watches
The time accuracy described on this instruction manual is the static accuracy
at normal temperature. The accuracy of mechanical watches may get out of the
described range depending on the following three usage conditions or other
reasons.
• Winding amount of the mainspring
• Attitude
• Usage environment (temperature, magnetism, impact, etc.)
Winding amount of the mainspring
Mechanical watches keep accuracy most stably when the mainspring is sufficiently
wound.
Attitude
Accuracy of mechanical watches varies affected by gravity. The accuracy varies
as the result that may take various attitude while worn and gravitate to a different
direction every moment.

Characteristics of Mechanical watches
Usage environment (temperature, magnetism, impact, etc.)
• Metal parts are used for the part for keeping accuracy in mechanical watch. The
accuracy varies affected by their thermal expansion and contraction.
• Metal parts are used in mechanical watches. Magnetism affects them and
accuracy of the watches in consequence. Do not bring them close to things which
have or generate strong magnetism.
• Strong shocks may also affect the accuracy.
Maintenance
Mechanical watches may become inaccurate due to insufficient lubrication or worn
parts. Have the watch disassembled and cleaned (overhaul) every 2-3 years (charge
basis). It may be difficult to restore the watch from degradation after long-term use
to its initial performance even after repairs.

■Water-resistant to 200m
• This watch is a scuba diver’s watch (water-resistant to 200m). You can use it
for scuba diving with air tanks, but must not be used in a helium-enriched
atmosphere (e.g. saturation diving).
■Automatic winding movement
• A automatic winding movement is employed in which the watch mainspring
is wound automatically by movement of the hand when worn, and the force of
the mainspring is then used to drive the movement (watch).
[Automatic winding]
When worn on the wrist, the normal movement of the arm will wind the mainspring.
[Manual winding]
Rotate the crown clockwise while it is in position to wind the mainspring.
