The Adrianov compass (russian: Компас Адрианова) is a military
compass designed by
Russian Imperial Army topographist in 1907. Wrist-worn versions of the compass were then adopted and widely used by the
Red and
Soviet Army.
Some of the older production examples (differentiated by the brownish color of their
glow-in-the-dark markings, like the one in the photo) are slightly
radioactive because of
Radium-226 used in
their dials. Newer ones, with teal or white paint color, use the non-radioactive
phosphorescent paint.
