b CAUTION
Please note that there is a risk of minor injury or material damage if the following safety regulations are not strictly observed.
HOW TO USE
Do not turn or pull out the crown when the watch is wet.
Water may get inside of the watch. * If the inner surface of the glass is
clouded with condensation or water droplets appear
inside of the watch for a long time, the water resistant performance of the
watch is deteriorated. Immediately consult the retailer from whom the watch
was purchased or SEIKO CUSTOMER SERVICE CENTER.
Do not leave moisture, sweat and dirt on the watch for a long time.
Be aware of a risk that a water resistant watch may lessen its water resistant
performance because of deterioration of the adhesive on the glass or gasket,
or the development of rust on stainless steel.
Do not wear the watch while taking a bath or a sauna.
Steam, soap or some components of a hot spring may accelerate the
deterioration of water resistant performance of the watch.
EN 7
b WARNING
1
HOW TO USE
Do not use the watch in scuba diving or saturation diving.
The various tightened inspections under simulated harsh environment, which are
usually required for watches designed for scuba diving or saturation diving,
have not been conducted on the water resistant watch with the BAR (barometric
pressure) display. For diving, use watches specifically designed for diving.
b CAUTION
Do not pour running water directly from faucet. The water pressure of tap
water from a faucet is high enough to degrade the water resistant performance
of a water resistant watch for everyday life.
HOW TO USE

Mechanical watch characteristics (Hand-wound, auto-wound) 1
· This is a mechanical watch powered by a spring. · To use it from a stopped
state, turn the crown 20 turns by hand to wind up the spring before starting
the
watch. · Although the accuracy of quartz watches is measured in differences
over months or years, in mechanical
watches it is measured in differences per day (i.e., the amount the watch
speeds up or slows down in a single day). · Additionally, mechanical watches
are subtly affected by the conditions in which they are used (e.g., duration
worn, temperature, arm movement, the amount wound, etc.) ; thus, the amount of
error is not constant. · When affected by a strong magnetism from outside, a
mechanical watch may lose/gain time temporarily. The parts of the watch may
become magnetized depending on the extent of the effect. In such a case,
consult the retailer from whom the watch was purchased since the watch
requires repair including demagnetizing.

How to wind the mainspring
HOW TO USE
· This is an automatic mechanical watch with a manual winding mechanism.
· When the watch is worn on the wrist, the mainspring is wound automatically
through normal wrist movement. The watch can also be wound up by turning the
crown.
· To start the watch after it stops completely, wind it up either by turning
the crown or swinging it from side to side until the seconds hand starts
moving. Then, set the time and date before putting the watch on the wrist. To
wind up the watch, turn the crown clockwise slowly. The watch cannot be wound
by turning the crown counterclockwise. In this way, the watch can be wound up
fully. Furthermore, turning the crown further will not break the spring.
- For the watch with screw down crown, please unlock the crown before operating it and be sure to lock the crown after operating it.
· Wind the mainspring until the power reserve indicator shows a fully-wound state. Once the watch is wound up fully, it operates for about 41 hours. - To check the winding state of the mainspring, refer to “Power reserve indicator” P.13.
EN 11
Crown
1
HOW TO USE
There are two types of crowns, a normal crown and a screw down crown. Please check the type of the crown of your watch.
While pressing the crown in, turn it in the direction indicated by the arrow.
The crown turns.
Normal crown Pull out the crown and operate it.
Screw down crown
The crown does not
turn.
Unlock the crown before operating it.
Unscrew
After operating the crown, lock it.
Rotate while pressing the crown in.
- By locking the crown by screw, a screw down crown can prevent malfunction and increase water resistance. * Be careful not to screw the crown in by force as it may damage the slots of the crown.
EN 10
- If the watch is used without being wound up fully, gain or loss of time may result. To avoid this, wear the watch for more than 10 hours a day. If the watch is used without being worn on the wrist, be sure to wind it up fully every day
1
at a fixed time.
HOW TO USE
- If you use a watch that has stopped with the mainspring unwound, winding the mainspring with the crown will not start the watch immediately. That is because the mainspring torque or force is low at the beginning of its winding due to the characteristics of mechanical watches. The seconds hand will start to move when a certain degree of torque is reached after the mainspring has been wound up. However, swinging the watch from side to side to forcibly turn the balance can start the watch sooner.
EN 12
1
Power reserve indicator
HOW TO USE
· The power reserve indicator lets you know the winding state of the
mainspring. · Before removing the watch from your wrist, observe the power
reserve indicator to check if the watch
has stored enough power to keep running until the next time you wear it. If
necessary, wind the mainspring. (To prevent the watch from stopping, wind the
mainspring to store the excess power that will allow the watch to run for
extra time.)
Power reserve indicator
- The continuous operating time of the watch may vary depending on the conditions of your usage (such as the number of hours you wear the watch or the extent of your movement while wearing it).
- In a case where you wear the watch for a short period of time each day, observe the power reserve indicator to check the level of the remaining power. If necessary, manually wind the mainspring.
EN 13
1
How to set the time and date
HOW TO USE
The watch is provided with a date function and is so designed that the date changes once every 24 hours. The date changes around 12 o’clock midnight. If AM/PM is not properly set, the date will change at 12 o’clock noon.
b CAUTION
Do not set the date between 9:00 p.m. and 1:30 a.m. Amending the date during
this time period may cause problems such as the date failing to change the
next day.
How to read the power reserve indicator
1
HOW TO USE
· As shown in the diagram below, when the indicator is pointing near 40 or F on the scale, it is fully wound. As the mainspring unwinds, the indicator will move toward 0 or E. The accuracy of a mechanical watch is affected by the winding amount of the mainspring. If the watch is used for a long time when the winding amount is 20 hours or less, stable accuracy may not be obtained. Therefore, it is recommended that the winding amount be between 20 hours and full winding when you use the watch. Once the mainspring is fully wound, it will slip if you wind it further, so there is no chance of the mainspring breaking even if it is over wound. * The indicator may move beyond 0 or E, but this is not a malfunction.

HOW TO USE
Pull out the crown to the second click when the seconds hand is at the 12 o’clock position; the seconds hand stops on the spot. Turn the crown to advance the hands until the date changes to the next. The time is now set for the A.M. period. Advance the hands to set the correct time.
4 Push the crown back in to the normal position in accordance with a time signal.
The seconds hand immediately starts moving. The telephone time signal service is helpful for setting the seconds hand exactly. For models with screw down crown, please be sure to lock the crown after operating it.
b CAUTION
The mechanism of mechanical watches is different from that of quartz watches.
When setting the time, be sure to turn back the minute hand a little behind
the desired time and then advance it to the exact time.
EN 17
HOW TO USE
1 How to use the simplified world time function (Only for models with the
simplified world time function)
By using the names of major world cities shown on the rotating bezel and the
24-hour display on the dials, the approximate time in each city can be read. ·
This is only a simplified world time function, and should not be used where
accuracy is critical.
Example: When in Tokyo and wanting to know the time in Paris 1 Check the
current time in Tokyo. (In this case, the time is 14:00 [2:00 p.m.].)
2 Set the rotating bezel to align “TOKYO” with the 14 indicator.
3 Check to see what time “PARIS” aligns with on the rotating bezel. (In this
case, it aligns with 6, and therefore it is 6:00 a.m. in Paris.)
Time in other cities may be read in a similar way. For example, the time in
Los Angeles can be read as 21:00 (9:00 p.m.).
EN 19
Date adjustment at the end of the month
1
It is necessary to adjust the date at the end of February and 30-day months.
HOW TO USE
Ex.) To adjust the date in the A.M. period on the first day of a month following a 30-day month The watch displays “31” instead of “1.” Pull out the crown to the first click. Turn the crown counterclockwise to set the date to “1” and then push the crown back in to the normal position. * For models with screw down crown, please be sure to lock the crown after operating it.
Pull out the crown to the first click
b CAUTION
· Avoid amending the date when the watch is displaying between 9:00 p.m. and
1:30 a.m. Doing so may cause damage.

General Usage
1
If in distress, these signs should be drawn on the ground for search & rescue craft/parties.
HOW TO USE
The sign should be at least 10 meters square. The characters should be oriented in a north-south fashion.
On snow, the sign should be dug as a trench or raised so as to be readable through shading.
Clothing and equipment should be used if physical strength is insufficient. Grass, trees, or stones should
be used if available nearby.
In a rescue operation, aircraft may use loudspeakers and communication tubes to contact parties at ground
level, but the person in distress will find it difficult to reply. However, knowing these reply methods can
enable proper rescue.

time and stores it to emit light in the dark. For example, if exposed to a light of more than 500 lux for
approximately 10 minutes, Lumibrite can emit light for 3 to 5 hours. Please note, however, that, as Lumibrite
emits the light it stores, the luminance level of the light decreases gradually over time. The duration of the
emitted light may also differ slightly depending on such factors as the brightness of the place where the
watch is exposed to light and the distance from the light source to the watch.
- In general, when coming from a place that is bright to a place that is dark, it takes human eyes some time to adapt to the darkness making it difficult to see objects initially. (Dark adaptation)
- Lumibrite is luminous paint that stores and emits light, which is harmless to human beings and the environment, containing no toxic materials such as radioactive substances.

Band
2
The band touches the skin directly and becomes dirty with sweat or dust. Therefore, lack of care may accelerate deterioration of the band or cause skin irritation or stain on the sleeve edge.
The watch requires a lot of attention for long usage.
Metallic band
· Moisture, sweat or soil will cause rust even on a stainless steel band if
they are left for a long time. · Lack of care may result in a rash or cause a
yellowish or gold stain on the lower sleeve edge of shirts. · Wipe off
moisture, sweat or soil with a soft cloth as soon as possible. · To clean the
soil around the joint gaps of the band, wipe it out in water and then brush it
off with a soft
toothbrush. (Protect the watch body from water splashes by wrapping it up in
plastic wrap etc.) Clean it off with a soft cloth. · Because some titan bands
use pins made of stainless steel, which has outstanding strength, rust may
form in the stainless steel parts. · If rust advances, pins may poke out or
drop out, and the watch case may fall off the band, or the clasp may not open.
· If a pin is poking out, personal injury may result. In such a case, refrain
from using the watch and request repair.

· The power transmission gear of the movement of this watch constantly receives force. To ensure that
this mechanism works properly all the time, washing parts, changing oil, adjusting accuracy, checking
functions and replacing consumable parts on a regular basis are important. The first overhaul after the
purchase of your watch is particularly important for preserving long-time use of your watch. According
to use conditions, the oil retaining condition of your watch mechanical parts may deteriorate, abrasion
of the parts due to contamination of oil may advance or delay the time significantly, or the watch itself
may stop.
As the parts such as gasket may deteriorate, water resistant performance may be impaired due to
intrusion of perspiration and moisture.
Inspection and adjustment by disassembly and cleaning (overhaul) should be performed by the retailer
from whom the watch was purchased, and who specifies “SEIKO GENUINE PARTS.” At this time, also
request replacement of the gasket and the spring bar.
· When your watch is inspected and adjusted by disassembly and cleaning (overhauled), the movement
of your watch may be replaced.

Accuracy of mechanical watches
2 The accuracy of mechanical watches is indicated by the “daily rate.”
The accuracy of mechanical watches may not fall within the specified range of
time accuracy because loss/gain changes according to the position of the
watch, which is dependent on the conditions of use, such as the length of time
during which the watch is worn on the wrist, arm movement, and whether the
mainspring is wound up fully or not, etc.
The loss/gain of mechanical watches is not measured by a daily rate, but by
daily rates of one week or so.
Accuracy variation according to temperature
The parts that compose the accuracy of mechanical watches are made of metals.
It is well known that metals expand or contract depending on temperatures due
to metal properties. This exerts an effect on the accuracy of the watches.
Mechanical watches tend to lose time at high temperatures while they tend to
gain time at low temperatures.

Mainspring wound condition and accuracy
In order to improve accuracy, it is important to regularly supply energy to the balance that controls the speed
of the gears. The driving force of the mainspring that powers mechanical watches varies between when fully wound and immediately before it is unwound. As the mainspring unwinds, the force weakens.
2
Relatively steady accuracy can be obtained by wearing the watch on the wrist frequently for the self-winding
type and winding up the mainspring fully everyday at a fixed time to move it regularly for the wind-up
mechanical type.
Effect of magnetism
When affected by a strong magnetism from outside, the mechanical watch may
lose/gain time temporarily. The parts of the watch may become magnetized
depending on the extent of the effect. In such a case, consult the retailer
from whom the watch was purchased since the watch requires repair including
demagnetizing.
