Shock-Proofing of watch

Most watches are sturdy enough to protect against normal everyday wear and tear, including light bumps. If you’re going to be engaging in intensive athletic activity, you may want a watch that is also shock-proof. For example, G-Shock by Casio is an extensive line of shock-proof watches.
