Seiko 5R86 User Guide - Page 3

English 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. 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.
