BASIC OPERATION INSTRUCTIONS
HOW TO SET THE TIME ON AN ANALOG WATCH
Gently pull the crown out as far as it will go. The watch will not run when
the crown is in this “set” position. If the watch has a “screwdown locking
crown,” you may have to “unlock” it before you can pull the crown out. To do
this, rotate the crown counter-clockwise (toward the bottom of the watch.)
This unlocks the crown. Once it is unlocked, gently pull the crown out as far
as it will go.
Then, rotate the crown clockwise (toward the top of the watch) so the hands
advance past the 12 o’clock position. If the day/date changes you are in the
AM position, if the day/date does not change you are in the PM position.
Proceed to set the correct time and push the crown all the way back in. Note:
it is best to set the time and date in the AM for instant day/date setting.
HOW TO SET THE DAY/DATE ON AN ANALOG WATCH
To set the day/date on an analog watch, gently pull the crown out to the first click position.
Rotate the crown clockwise (toward the top of the watch face). The date on the watch will advance. If the number showing in the window is too high, go past “31,” and the counter will start at “1” again.
If your watch also displays a day-of-the-week, set this by rotating the crown counter-clockwise (toward the bottom of the watch face). The dayof-the-week will advance, going past Sunday and restarting at Monday, if necessary. Stop one day before the correct day-of-the-week.
Next, pull the crown out another stop and turn it clockwise so the hands move forward. When you pass 12, the day and date should change automatically to the correct date. If you are setting the watch before noon, stop as soon as you get to the correct time and push the crown all the way back in. If you are setting the watch after noon, go past 12 again before you stop at the correct time and push the crown all the way back in. If the watch is a “screwdown locking crown,” relock the crown after setting the correct time by pressing down on the crown as you turn it clockwise.
CHRONOGRAPHS
A Seiko chronograph is not only a watch, it is also a sophisticated stopwatch that can measure down to fractions of a second and includes functions such as
- elapsed time,
- accumulated time, which allows you to track playing time, and stop the clock during time-outs,
- split time measurement, which allows you to make submeasurements of times for laps or legs of a race or to time two different racers.
USING ANALOG CHRONOGRAPH FUNCTIONS
The chronograph functions are operated by pressing the buttons on the side of
the case.
-
STANDARD TIMING
To measure how long it takes someone to go from point A to point B, simply push button A to stop and start the stopwatch, which displays time in the sub dials, and use button B to reset. -
ELAPSED TIME MEASUREMENT
To record elapsed time, use button A to start, stop and restart as often as required. Use button B to reset after the match is over. -
SPLIT TIMING
Press button A at the start of the race. Press B to check the time for one segment of the race, the press B again to return to a display of total running time. Press A at the end of the race, then use B to reset. -
TIMING TWO COMPETITORS
Press button A at the start of the race. Press button B to see the time for the first finisher. Press A when the second competitor finishes, then press B to see the finish time. Reset by pushing B again.

KINETIC ® ELECTRICALLY CHARGED EVERY TIME YOU MOVE YOUR BODY.
GENERATING UNIT
Transforms the movement of the wearer into electricity.
-
OSCILLATING WEIGHT
The everyday movement of your wrist rotates the oscillating weight. -
GEAR TRAIN
This amplifies the rotational movement of the oscillating weight 100 fold and transfers it to the rotor. -
ROTOR
This is where the magic begins. Every movement of the oscillating weight is turned into a magnetic charge. It can spin up to 100,000 RPM-faster than a Formula One race car. -
GENERATING COIL BLOCK
Extremely high density coil transforms the magnetic charge into the electricity to power the watch. -
KINETIC ENERGY STORAGE UNIT
The electrical energy is stored in this tiny technological marvel. CHARGING UNIT
Stores and supplies the generated electricity.
-
CIRCUIT BLOCK
Vital to the process, this electronic circuit controls voltage, amps and by quartz oscillation, produces a precise watch signal. -
QUARTZ CRYSTAL OSCILLATOR
When electricity is passed to it, it oscilllates at a highly stable rate of 32,768 times a second. -

KINETIC
SEIKO KINETIC watches are marvels of brilliantly applied technology.
They convert energy created by the movement of the wrist into electricity
which is stored, regulated and released with perfect quartz accuracy. No need
to ever change a battery.
HOW TO CHARGE SEIKO KINETIC SEIKO KINETIC
watches must be charged before they are set. Charging is simple. Gently swing
the watch from side to side in a small arc for two to three minutes. As you
swing the watch, the oscillating weight in the generating system may give out
a small sound as it rotates. When the second hand begins to move in one second
intervals, the watch has stored at least three hours of power and is ready to
be set.
CHECKING THE POWER RESERVE
The power reserve indicator function shows how much energy is stored in the
watch’s capacitor. To check how long the watch can operate on its current
charge, wait until the second hand is in the 12 o’clock position and press the
button at the 2 o’clock position on the watch case. Then use the chart below
to determine how much stored energy is indicated by the number of seconds that
the second hand moved. The secondhand will resume normal operation in 30
seconds or less.
MOST COMMON KINETIC CALIBERS
LOW ENERGY RESERVE WARNING
When the second hand starts to move in two-second intervals instead of the
usual one-second intervals, the watch’s energy reserves are low. The watch
should be charged by swinging it gently from side to side in a small arc for
approximately one minute.
KINETIC AUTO RELAY
SEIKO KINETIC AUTO RELAY is an enhanced version of SEIKO KINETIC which features power saving and time relay functions that keep the watch operating for up to four years, even if left unused.
When the watch is not in use, time is still calculated in the Integrated Circuit (IC), but the watch hands stop moving in order to save energy. When the watch is picked up and moved again, the KINETIC power generating system is activated and the correct time is automatically relayed from the IC to the hands, which quickly reset themselves to the exact time.
ADVANCED FEATURES:
- Automatic power generator (see description of KINETIC watches)
- Automatic energy saving function
- Manual energy saving function
- Time Relay function
- Energy depletion warning function
AUTOMATIC ENERGY SAVING FUNCTION
If the watch is left untouched for approximately 3 consecutive days, the hands
will automatically stop moving to save energy, while the advanced integrated
circuit (IC) continues to keep track of the time.
MANUAL ENERGY SAVING FUNCTION
You can also activate the energy saving function manually by pulling the crown
out to the first click position and pushing it back in to its normal position
in less than a second.
Warning: Do not pull the crown out to the second click position while the
energy saving function is in operation. This will cause the time data retained
in the watch to be erased, thus disabling the time relay function.
TIME RELAY FUNCTION
The Time Relay function automatically resets the watch hands to the correct
time when the watch is reactivated after being in the energy saving function
mode in which the hands don’t move. The correct time is “relayed” from the
built-in IC to the hands, which begin to move again.
All you have to do is swing the watch gently. This generates electricity which
automatically activates the Time Relay function, and the hands are adjusted
automatically to the time retained inside the watch’s IC. If the watch is
fully charged when the power saving function is activated, the Time Relay
function remains operable for approximately four years.
ENERGY DEPLETION WARNING FUNCTION
As with all SEIKO KINETIC and KINETIC AUTO RELAY watches, when the second hand
starts to move in two-second intervals instead of the usual onesecond
intervals, the watch’s energy reserves are low. The watch should be charged by
swinging it gently from side to side in a small arc for approximately one
minute.
PERPETUAL CALENDAR
Crown
Pull out to second click when second hand is at the 12 o’clock position. Turn
in either direction to set the time and date. Push back completely in
accordance with a time signal.
Each Seiko Perpetual Calendar is a masterpiece of advanced timekeeping. The calendar is pre-set at the factory and will automatically adjust for the length of every month, including February in leap years, up to February 28, 2100. To reduce the need to ever reset these watches, they are highly accurate, with a yearly gain or loss of less than 20 seconds. In those models that feature Dual Time and World Time Display, you can set the watch for a second time zone when you travel without disturbing the setting for your home time zone.
CHECKING THE CALENDAR
Because the watch may have crossed international date lines since it was
originally set, you should check that the calendar is correct before setting
the watch. To do this, pull the crown out to the first click position, and
push it back in quickly (in less than a second.) If the watch has a screw lock
crown, you will need to unscrew the crown by turning it counterclockwise
before you can pull it out.
-
First, the number for the current month will be displayed in the calendar window for five seconds, (January is “1,” February is “2” etc.)
-
Then the calendar window will return to displaying the number for the date.
PRO TIPS: -
Be sure you pull the crown out only one click. If the crown is pulled out to the second click position before it is pushed back in, the calendar will not be displayed.
-
Be sure to push the crown back into its normal position against the watch case. Leaving the crown out in the first click position will shorten battery life.
LEAP YEAR INDICATION
Seiko Perpetual Calendar watches also include a function in which the second
hand indicates the number of years since the last leap year. With the second
hand at the 12 o’clock position, pull the crown out to the first click
position then push it back to the normal position quickly (within a second).
The second hand will move to the 5 second position indicating one year has
passed since leap year — the 10 second position indicates two years etc
SETTING A PERPETUAL CALENDAR WORLD TIMER
Because this watch is designed with an hour hand that can move separately from
the other hands, setting procedures are a bit different.
You can set the watch into two different modes:
- so the 24-hour hand shows 24-hour time and acts as an AM/PM indicator while the hour hand shows 12-hour time, or
- so the 24-hour hand shows the time in a different time zone from the time shown by the hour hand.
-
Pull the crown out to the second click position when the second hand is at the 12 o’clock position.
2A)For a single time zone, so the 24-hour hand indicates AM/PM. Turn the crown in either direction to set the minute hand and 24 hour hand to the current time in your area, using the 24-hour marks on the dial.
OR
2B) To use the 24-hour hand to indicate time in another zone. Turn the crown in either direction to set the minute hand and 24 hour hand to the time in another area, positioning the 24-hour hand as if it were a 12-hour hand -
Push the crown all the way back in.
-
Now pull the crown out to the first click position and rotate it in either direction, moving the hour hand around the dial (it moves in one hour increments )until both the date and hour are correct for your area.
-
Push the crown all the way back in.
READING WORLD TIMES ON ROTATING BEZEL MODELS
To read the times for 22 cities in different time zones around the world:
- Turn the rotating bezel so that the 24-hour hand points to a city in the time zone it has been set for
- The times for various cities will be indicated by the 24-hour marks next to them.
The 24-hour hand will continue to indicate the time of the area you had previously set the watch for.
BATTERY LIFE INDICATOR
When the second hand starts to move in two-second intervals instead of the
normal one-second intervals, replace the battery within two weeks. The
calendar function should not be affected by battery changes, as long as the
watch has not been allowed to stop completely. Nonetheless, it is still a good
idea to check that the calendar is correct after a battery change.
