To
wind a timepiece that has stopped, hold your automatic watch in your
hand with the dial facing up. Gently move your arm back and forth to
gently shake the watch. You should hear or feel the movement in motion.
After a couple of minutes, the watch will have enough stored energy to
run for a couple of hours. Put the watch on and the motion of your arm
will continue to build the energy reserve.
Invest
in a watch winder if you have several automatic watches. A winder has
one or more rotating knobs for storing automatic watches. The knobs
rotate at a constant speed to keep automatic watches ready for wear.
However, the uninterrupted rotation can be stressful on the movement
parts and the winder should only run for a few hours at a time, perhaps
overnight.
