The signal watch is a watch used by Superman and Supergirl's allies to contact the heroes for emergencies.

History

Superman gave James Olsen the watch just in case he ever got into trouble, so the latter would be able to contact him. James is also able to use the watch to communicate with Supergirl when she is in the field.

When Supergirl was overwhelmed by Reactron, James used the signal watch to summon Superman to National City as backup.[1]

Following Reign's defeat, Alex Danvers gave Ruby Arias a signal watch as a parting gift.[2]

Soon after Eve Teschmacher shot James in his office at CatCo, she activated the signal watch to summon Supergirl as a part of Lex Luthor's scheme.[3]

At some point, Kara gave Alex a signal watch if her sister ever needed help. Kara and Alex also arranged a special code between them for whenever the latter uses the signal watch: pressing it once means that Supergirl should come; pressing it twice means that she shouldn't come, because it's a trap.[4]

After Lena Luthor discovered her secret identity, Kara gave her a signal watch to use in emergencies.
