Seiko 5R65 Manual - 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. 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. 4 English NAMES OF THE PARTS Hour hand Minute hand Date Second hand Power reserve indicator 6 CROWN a b c CROWN a) Normal position : winding up the mainspring (manual operation) b) First click position : date setting c) Second click position : time setting [Caliber 5R65] 5
