TECHNICAL GUIDE 9.To wind up the mainspring <<Movement>> The mainspring would be fully wound up by turning the ratchet wheel screw 8 times clockwise. (Manual winding or Screwdriver) Manual winding Rotate crown clockwise at normal position by minimum 55 times. (Equal to ratchet wheel screw 8 times ) Screwdriver winding Turn the ratchet wheel screw 8 times clockwise. [ Manual winding ] [ Screwdriver winding ] Screwdriver Ratchet wheel screw Ratchet wheel 10.How to attach hands Place the movement directly on a flat metal plate or something similar to attach the hands. We recommend the use of movement holder to attach hands. For hands attachment, please use a special equipment. When the movement receives a strong shock, it may be damaged. <<Note: Power reserve hand setting>> (1)The mainspring should be fully wound up before setting power reserve hand. (2)Set power reserve hand at the fully wound up position of the dial graduation.

OPERATION [ NE57A operation manual ] Minute hand Hour hand Second hand Date hand Crown at normal position Second click First click Power reserve hand 1.How to set the time 1) Pull out the crown to the second click position. 2) Turn the crown to set hour and minute hands. (Check that AM/PM is set correctly.) 3) Push the crown back into the normal position. *When time setting is performed in counterclockwise, date hands reverses. Please reset by date correction. 2.How to set the Date hands 1) Pull out the crown to the first click position. 2) Turn the crown to left for date setting. * Do not set the calendar between 9:00 P.M. and 2:00 A.M. If the setting of the calendar is made during this period, the date will not change to the next date. Please set the calendar after changing the time other than the above period. 4) Push the crown back into the normal position. 3.To wind up the mainspring a) Manual winding Rotate the crown clockwise at normal position. Wind turning the ratchet wheel screw 8 times. It will start to move naturally after shaking slightly. b) To wind up with winding machine.
