B. Charging by Swinging the Watch
When there are few opportunities for charging the watch by exposing to light, occasion-
ally charge the watch by swinging. In addition, for those persons who only wear the
watch for short periods of time (several days) or when there is little movement while
wearing the watch, it is also recommended to charge the watch by swinging.
Swing the watch back and forth over a dis-
tance of about 20-25 cm (8-10 in.) at the rate
of about 2-2.5 strokes per second.
* Swing the watch for about 300-500 times
(strokes) when it has stopped.
<How to Effectively Charge the Watch by Swinging>
Examples:
* Charging in close proximity to an incandescent lamp or halogen lamp which can
easily reach high temperatures.
* Charging in locations that can reach high temperatures such as on an automobile
dashboard.
* When charging with an incandescent lamp, always make sure to keep the watch at least
50 cm (20 in.) away from the lamp to prevent the watch from overheating.
