You do not think about which arm we were wearing the wristwatch.
If we do not have a special reason, we have the right one on our left arm. The reason for our watch to our left arm is that we use our left arm less according to our right arm. We move our right arm before our left arm. Therefore, it prevents our wrist watch from hanging out and damage anywhere.
The settings of our wristwatches are in the middle of the number 3 in all of this institution process usually with the right hand. We can only apply our watch to our left arm even to apply the installation process easily.
The arm in which the female and male clock is attached is the same, the left wrist is attached.
