■ CHARACTERISTICS
Characteristics of the minute repeater
○ This watch features a mechanically-actuated minute repeater function that is powered by
mainsprings. It audibly chimes the current time with two different sounds, a high tone and
a low tone.
○ The number of times the low-tone gong is struck represents the hour, and the number of
times the sequence sound of the low-tone and the high-tone gongs are struck represents
the 10-minute intervals after the last hour, and the number of times the high-tone gong is
struck represents the minute.
Unlike most minute repeaters that represent a quarter hour by a sequence sound of the
low and high tones, the minute repeater of this watch has a decimal system so that the
indicated time is easily understood.
(For more details on the time announcement method, refer to P. 11.)
○ The source of the sounds which produce crisp, clear sounds are the rod-shaped gongs
made from specially hammered steel, using a technique passed down through generations
of the Myochin family, master blacksmiths from Himeji.
○ The volume of the striking gongs is tuned slightly louder so that you can comfortably enjoy
the passage of time and relaxed atmosphere in a quiet place without need for raising the
watch close to your ear.
* As the minute repeater is a mechanically-actuated time announcing device, an error of
approximately one minute may occur between the time indicated by the number of times
the gongs are struck and the time indicated by the hands of the watch.
Characteristics of spring drive
○ This watch features“ Spring drive”, the unique mechanism made available only by SEIKO
technology.
○ The Spring Drive watch ensures quartz accuracy while using the mainspring as its sole
power source.
○ The glide-motion seconds hand moves in a perfectly smooth movement.
bCAUTION
○ Spring Drive works by the power provided by the mainspring. Remember to check the
power reserve indicator and keep the mainspring of the watch sufficiently wound while
using the watch.
“Power reserve indicator”→ P. 9
○ Under a low-temperature condition (below 0°C), the watch may stop when the power
reserve indicator shows less than one-sixth of the power reserve.
In such a case, turn the crown to wind the mainspring.

■ HOW TO USE
How to wind the mainspring
This watch has a manually wound spring drive.
You can wind the crown to wind the mainspring to drive the watch.
The watch has two mainsprings, a first mainspring and a second mainspring. These two
mainsprings can be simultaneously wound with one operation.
Guide for winding state of the mainspring
Manual winding : Five full rotations of the crown will provide the power to run the watch
for approximately ten hours.
Observe the power reserve indicator to check the level of the remaining power.
“Power reserve indicator”→ P. 9
* Under a low-temperature condition (below 0 °C), always keep at least one-sixth of the
watch power shown by the power reserve indicator.
The watch may stop.
How to manually wind the mainspring
2Wind the mainspring until the power reserve indicator shows a fully wound state.
“Power reserve indicator”→ P. 9
3Make sure that the seconds hand is moving.
bCAUTION
The crown cannot be turned further when the mainspring is fully wound to prevent
overwinding of the mainspring. Do not try to forcefully turn the crown as this may damage
the watch.
1Turn the crown at the normal position
clockwise (12 o’clock direction)
slowly.
8HOW TO USE
Power reserve indicator
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

time after that, wait for approximately 30 seconds after the seconds hand starts moving,
then pull the crown out to the first click.
3The seconds hand will stop moving when the crown is pulled out to the first click. Do not
stop the movement of the seconds hand for longer than 30 minutes. If the stoppage of the
seconds hand movement exceeds 30 minutes, push the crown back in, and wait for
approximately 30 seconds after the seconds hand restarts moving, and then set the time.
10 HOW TO USE
How to use
Minute repeater function
The minute repeater function audibly chimes the time with two different sounds, a low-tone
gong and a high-tone gong.
The number of times the low-tone gong is struck represents the hour, and the sequence of
low-tone and high-tone gongs represents the 10-minute intervals after the last hour, and the
number of times the high-tone gong is struck represents the minute.
While most minute repeaters use a
sequence of low-tone and high-tone
gongs for quarter hours, the minute
repeater of this watch has a decimal
system, which makes its time
announcement easily understood.
Hour

2Second mainspring
The first mainspring is mounted on the front side and the second mainspring is mounted on
the rear side of the watch.
These mainsprings are the power source for the watch and minute repeater.
3One-way clutch
The one-way clutch transmits and interrupts the power generated by the mainsprings to the
minute repeater.
The one-way clutch slips when the mainsprings are wound and is locked when the minute
repeater mechanism is activated. When winding the mainsprings, you can view the
movement of two small springs and the slipping one-way clutch.
4Large hammer
The large hammer strikes the gong for a low-tone sound (sound source).
5Small hammer
The small hammer strikes the gong for a high-tone sound (sound source).
6Repeating rack
This is a mechanism for reading the number of times the gongs are struck.
Three repeating racks for the hour, 10-minute intervals after the last hour, and minute operate
in conjunction with each other.
When the button is pressed to activate the minute repeater, the repeating racks
instantaneously rotate and slowly return to the original position.
The number of times the gongs are struck is determined by the returning amount.
7Slow governor
The slow governor controls the speed at which the mainsprings are unwound and regulates
the chime intervals.
When the button located at the 8 o’clock position is pressed, the slow governor rotates at a
high speed, and stops after chiming is finished.
It uses the viscosity of air to minimize the operating sound.

Safety device of minute repeater mechanism
Failure of the minute repeater most frequently occurs due to operation of the crown when the
repeater mechanism operates.
In most watches which are mounted with a repeater function, when the crown is pulled out to
adjust the hand position while the minute repeater is chiming, an abnormal load is applied to
the gears or lever to cause a failure.
In order to prevent a failure from occurring because of the time setting while the minute repeater
is chiming, this watch is provided with a safety device that prevents both operations from being
performed at the same time.
◎The minute repeater cannot be activated while the time is
being adjusted.
When the crown is pulled out to the first click
position
Cannot be pushed in
The button located at the 8 o’clock
position cannot be pressed in the
state where the crown is pulled out to
the first click position.
* Please keep in mind that if the
button is forcibly pressed when the
crown is pulled out to the first click
position, this may result in a failure.
◎The following operations cannot be performed while the
minute repeater is chiming.

16 TO PRESERVE THE QUALITY OF YOUR WATCH
Daily care
The watch requires good daily care
○ The watch body and band touch the skin directly just as underwear.
Keep the watch body and band clean in order to avoid stain on the sleeve edge or rash or
itch.
After removing the watch from your wrist, wipe perspiration or moisture with a soft cloth as
soon as possible.
○ Do not use any chemical agent such as cleaner to clean the watch.
Turn the crown from time to time. (Only several turns in
slow movement will be enough.)
○ This prevents corrosion of the crown and helps to extend the life of the gasket in use.
○ Stainless steel is a highly rust-resistant metal. However, rust will form if contaminants are
left on it for a long time.
Remarks on 18-karat gold
○ 18-karat gold (18KT) is an alloy comprised of 75% of gold and 25% of other metals.
Depending on the proportion of the other metals mixed with the gold, the 18-karat gold is
classified into three colors such as yellow gold (YG), white gold (WG) and pink gold (PG).
Decoloration of 18-karat gold
○ While gold can maintain its glittering quality, other metal components in the alloy may
discolor to look like reddish or blackish due to various reasons.
○ Daily care helps to prevent discoloration of the alloy, however, if the discoloration or stain
of the alloy persists even after wiping the watch off, take your watch to the retailer from
whom the watch was purchased for refinishing. (Refinishing will be done at a cost.)
Watch body / metal bracelet
Length adjustment service
○ For the length adjustment service of the 18-karat gold or platinum bracelet, ask the retailer
from whom the watch was purchased.
The watch will be submitted to CREDOR SERVICE STUDIO for the length adjustment.
It may take two to three weeks depending on the model to adjust the length of the bracelet.
○
The length adjustment service of the 18-karat gold, platinum or stainless steel mesh bracelet
will not be charged only for the first time. However, the cost for materials or parts necessary
for the length adjustment and repair cost other than the length adjustment will be charged.
○ The length adjustment service of stainless-steel band is available from the retailer from

Band
The band touches the skin directly and becomes dirty from 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 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.)
Wipe off the remaining moisture with a soft cloth.
○ Because some titanium bracelets 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 bracelet,
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.
Leather band
○ A leather band is susceptible to discoloration and deterioration from moisture, sweat and
direct sunlight.
○ Wipe off moisture and sweat as soon as possible by gently blotting them up with a dry cloth.
○ Do not expose the watch to direct sunlight for a long time.
○ Please take care when wearing a watch with light-colored band, as dirt is likely to show up.
○ Refrain from wearing a leather band watch other than Aqua Free bands while swimming,
and when working with water even if the watch itself is water-resistant enforced for daily
use.
Notes on skin irritation and allergy
Skin irritation caused by a band has various reasons such as allergy to metals or leathers, or
skin reactions against friction on dust or the band itself.
Notes on the length of the band
Adjust the band to allow a little clearance with your wrist to ensure proper airflow.
When wearing the watch, leave enough room to insert a finger between the band
and your wrist.
