FEATURES

English

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. 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.

 

The caliber 5R65 has a second hand in the center of the dial. The caliber 5R64 has a small

 

second hand at the 9 o’clock position on the dial.

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, especially if it is left at a temperature below 0ºC.
