Communicator

The Communicators were special devices used by the Sailor Senshi to keep in touch with each other. Two sets appeared throughout the series, one being watches that came from the Sailor V video game that were destroyed before the start of Pretty Soldier Sailor Stellar. The second set was gifted by Luna and were designed after Sailor Moon's Crystal Star compact.

The Otaku Senshi have their own set of communicators designed after Hikari's Dark Moon Brooch, made by Saphir in the second arc. It's unknown how Uranus and Neptune acquired theirs.
