The medal is awarded by decision of the Council of the CMS.
The medal was issued on the occasion of the 15th anniversary of the CMS (that time Mathematical Research Section of the Union of Czechoslovak Mathematicians and Physicists). Its diameter is 80mm, average thickness 9mm.
The obvers depicts an astrolabe of the Prague Astronomical Clock as symbol of time, astronomic tower in Klementinum and the Carolinum in Prague, and Michal tower and the building of "Academia Istropolitana" in Bratislava. Above them there are silhouettes of the St. Vitus Dome with the Royal Palace in Prague and of the Bratislava Castle. On the right hand side there is the circular shield with the logo of the Union of Czechoslovak Mathematicians and Physicists (JČSMF), at the bottom is the year 1862 when the Union was founded. The right edge is trimmed with the Czech name of the Union (Jednota československých matematiků a fyziků).
On the reverse there is again the astrolabe and portraits of founders of modern Czech mathematics Karel Petr (1868–1950) and Bohumil Bydžovský (1880–1968) with their autographs. On top there is silhouette of the original seat of the Union on Prague Karlov (today the Faculty of Mathematics and Physics of the Charles University).
The medal was designed by the prominent Czech sculptor Zdeněk Kolářský.
