The mark consists of a drawing of a bird's head facing to the right and resting on the words "ON WATCH". The lower part of the bird's beak bends to the left. The feathers on the backside of the bird's head are drawn as triangles stacked vertically. None of the right sides of the feather triangles are drawn. Both the lower side of the bottom feather triangle and that of the lower mandible align with the center of the words "ON WATCH".
Color is not claimed as a feature of the mark.
