Automatic watches will generally run for 2-3 days before the spring is fully unwound, so you are likely to have bought the watch in the unwound condition.

It can be wound by gently shaking the watch from side to side (for about 100-200 times). This should give it sufficent engergy to operate and thereafter normal use will keep it wound up.

If it stops working when the watch is rotated out of the face up position, then it may be that the watch is faulty. (If the watch has been dropped in transit, it may have been damaged).

If normal operation is not achieved, then send it back to get it repaired under warranty.
