The inner side of the lid has geometrical decoration on the borders. Inside the brass case itself is a compass with a card, printed from an engraved plate and hand painted with a sun effigy in blue and pink. The hour lines are engraved around the compass and numbered from IIII to XII to VIII, together with the initials 'R G'. A decoration is engraved at the top and the bottom of the plate. Around the edge of the oval box is geometrical decoration. The dial also has a ring for suspension that suggests its possible use as a medallion.
