A white rectangular sundial plaque is affixed to a textured, light beige building wall

A white rectangular sundial plaque is affixed to a textured, light beige building wall. A metallic gnomon projects perpendicularly from the plaque's center. The plaque's surface displays black lines indicating hours from approximately 7 AM to 6 PM, with numbers 1 through 12 marking the time. One set of 12 o'clock is labeled "12 (CET)", and another set is labeled "12 (DST)". A specific date line is marked "19. VIII" (August 19th) with a Libra symbol. Inscriptions on the plaque are in Serbian Cyrillic and Latin script. At the top, "JЕВТО ДЕДИЈЕР (1879-1918)" is prominently displayed. Below this, "Требиње" is written, indicating the city of Trebinje, Bosnia and Herzegovina. Corresponding geographical coordinates are listed as "42° 43' N", "18° 21' E", and an altitude of "279 m". The bottom of the plaque states "ПОКЛОН ГЕОГРАФСКОГ ФАКУЛТЕТА ИЗ БЕОГРАДА" (Gift from the Faculty of Geography from Belgrade). The sundial is mounted slightly below an architectural overhang. To the right, a brown-framed window is visible, reflecting a distorted image of an adjacent building and sky. To the left, another window reflects a similar urban and sky view. The wall texture consists of small, uniform protrusions.
