FEATURES
Spring Drive, the unique mechanism made available only by SEIKO technology,
ensures high accuracy while using the mainspring as its sole power source.
The watch will work continuously for approximately 7 hours (three days) when the
mainspring is fully wound. The watch features a power reserve indicator to show
the winding state of the mainspring. The glide-motion second hand works in a per-
fectly smooth movement.
This is an automatic watch equipped with a manual winding mechanism. When first
using the watch, manual winding is convenient.
CAUTION
•
This watch is powered by the mainspring. To ensure constant operation
of the watch, be sure to wind up the mainspring sufficiently before the
power reserve indicator points to " 0."
•
The watch may stop if the power reserve indicator is showing less than
one-sixth of the power reserve, especially if it is left at a temperature
below 0ºC.
