■ CHARACTERISTICS

● 200-meter water resistance
This watch is designed for diving using compressed air cylinder featuring a superior water resistance property to
withstand depths down to 200 meters. （The watch cannot be worn during saturation diving which uses helium gas.）
● Spring Drive
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 68.
