■ CHARACTERISTICS

Spring Drive, the unique mechanism made available only by SEIKO technology, ensures
quartz accuracy while using the unwinding power of the mainspring as its sole power
source.
In addition to the self-winding mechanism, which uses the natural motion of the wearer's
arm as a power source to wind its mainspring, the watch is equipped with the manual
winding mechanism, which is convenient to wind the mainspring when you start using the
watch.
The watch keeps working for approximately 72 hours （three days） when the mainspring
is fully wound.
The watch features the power reserve indicator to show the winding state of the
mainspring （the amount of the remaining power） .
The glide-motion second hand that moves around the dial in a perfectly smooth
movement is one of the remarkable features of this watch.
※ For the details of the Spring Drive mechanism, refer to the separate volume "Spring Drive Handbook".
※ 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" on page 53.
