Before starting repairs, read this manual carefully to understand the features of this watch and strictly
observe the instructions regarding how to perform repairs and checks in order to ensure appropriate
work is carried out.
Features of Cal. 7L22A
The Cal. 7L22A is a fully-fledged chronograph featuring a Kinetic Automatic Generating System.
5M6 series parts are used for the Automatic Generating System and 7N series parts are used for the
wheels and motors.
1. Stopwatch functions
◆The stopwatch is designed to time up to 45 minutes in 1/5 second increments.
◆The measured time is indicated by two stopwatch hands.
◆After timing for 45 minutes, it continues timing up until 48 minutes before automatically stopping.
◆The stopwatch can be reset even while it is currently timing.
◆Stopwatch Operation:
Button A : Start/ Stop
Button B : Reset
BEFORE STARTING REPAIR WORK ON 7L22A
◆Heartcam Chronograph Reset:
The two stopwatch hands are instantaneously reset to the zero position.
◆Measuring methods:
Standard measurement
Accumulated elapsed time measurement
2. Kinetic features
◆The watch will keep operating for approximately 5 months when fully charged under the condition
that the stopwatch is used for no longer than for 45 minutes per day.
◆Energy Depletion Forewarning Function
When energy is running low, the small second hand will start moving in two-second intervals to
indicate recharging is required. If the watch is not recharged at this time, it will run down within
approximately 12 hours after the initial forewarning.
◆Gently swing the stopped watch from side to side at least five hundred times until it returns to its
normal one-second intervals from the two-second intervals.

FEATURES
SEIKO KINETIC Cal. 7L22 is an analogue quartz watch equipped with an Automatic
Generating System developed by SEIKO. It generates the electric energy to power the
watch, utilizing the movement of the arm, and stores it in the KINETIC ELECTRICITY
STORAGE UNIT (KINETIC E.S.U.), which requires no periodical replacement unlike
conventional button-type batteries.

POWER RESERVE IN YOUR SEIKO KINETIC WATCH
●The electric energy generated while the watch is worn on your wrist is stored in the

CAUTION
Never install a silver oxide battery for conventional watches in place of the KINETIC
E.S.U. The battery may burst, become very hot or catch fire. Even if the battery
is installed, electricity will not be conducted.
ENERGY DEPLETION FOREWARNING FUNCTION
●When the second hand starts moving at two-second intervals instead of the normal
one-secondintervals,thewatchwillrundowninapproximately12hours.
*If the second hand starts moving at two-second intervals while the stopwatch is in use, the watch will
run down in approximately 45 minutes assuming the stopwatch remains in use. (Refer to “HOW TO

REMARKS ON THE KINETIC E.S.U.
●Donotpullthecrown outtothesecondclickwith the intentionofstoppingthesecond
hand just to save energy. By doing so, a large amount of current flows through the
built-in IC. Therefore, pulling out the crown to the second click will not save energy
but,infact,consumemoreenergythanusual.
