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 72 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 perfectly
smooth movement.
This is an automatic watch equipped with a manual winding mechanism. When first
using the watch, manual winding is convenient.
Caliber 5R66, which is equipped with a 24-hour hand, features an hour-hand inde-
pendent adjustment function (for time difference adjustment), offering several types
of 24-hour hand usage. For instance, if you set the 24-hour hand to show your home
time, you can independently set the hour hand to display the time of the place you are
staying at as well as easily check your home time by the 24-hour hand. Alternatively,
you can set the 24-hour hand to display the time in a different time zone. Caliber 5R67
features a moon phase display function.
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.
