Here is the information from the website. The link to the manual is provided below. HOW TO CHARGE AND START THE WATCH Swing the watch from side to side approximately 50 times. * Before swinging the watch, check and remember where the minute hand is so that you can tell if the start-up indicator has worked or not. First, check that the crown is at the normal position. * If the crown is pulled out and the watch is swung, the start-up indicator will not work even if the watch starts operating. * Swing rhythmically at a rate of twice a second. * No additional benefit is obtained by swinging the watch more quickly or with greater vigor. * When the watch is swung, the oscillating weight in the generating system rotates to drive the mechanism. As it rotates, it gives out a sound, which is not a malfunction. 1 2 The minute hand moves quickly and stops as the watch starts operating. (Start-up indicator) Then, it will move at 20-second intervals. 3 After checking that the minute hand has done this, pull out the crown to set the time. 4 After pushing back the crown in to the normal position, swing the watch further approximately 350 times to reserve one day of power, and then, put the watch on your wrist. http://www.seikowatches.com/support/ib/pdf/1m20_e.pdf Good luck, Techjoel
