■ CHARACTERISTICS
Spring Drive, the unique mechanism made available only by SEIKO technology, ensures quartz accu-
racy while using the mainspring as its sole power source.
With Spring Drive as its basic structure, the Spring Drive Chronograph features the world's first
center chronograph that has a glide-motion second hand.
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 glide-motion second hand that moves around the dial in a perfectly smooth movement is one of the
remarkable features of this watch.
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.
Refer to "POWER RESERVE INDICATOR" on page 58.
