Caring for your early 20^th century watch: watches of this period are not sealed so they should not be worn near water, Even hand washing or wearing in the rain can cause damage to the movement. If your watch does get wet please dry it as quickly as possible. You can open the case to make sure there is no water in the movement. An annual service will keep the watch in best condition.
