Crimson Dawn's Hylobon Enforcers utilized a wrist comm device.
A wrist-mounted communication device, known by names like wrist link or wrist comm, was designed to be worn on the arm. It functioned similarly to a comlink, providing a means of communication. Many wrist comms also included a built-in chrono. During the time of the Age of the Empire, the Hylobon Enforcers serving Dryden Vos used wrist comms to stay in contact with each other and their boss. Omega was in possession of Crosshair's wrist comm until Cad Bane destroyed it on Bora Vio. The rebel Ezra Bridger sported a wrist comm on the left sleeve of his jacket.
