History
The Param Vishisht Seva Medal was originally instituted as the "Vishisht Seva Medal, Class I" on 26 January 1960. Five other medals were instituted on the same day: the Sainya Seva Medal, Sena Medal, Nao Sena Medal and the Vayu Sena Medal. It was renamed on January 27, 1961, and the badge signed. Design 
The medal is round in shape, 35 mm in diameter and fitted to a plain horizontal bar with standard fitting. It is made of gold gilt. On its obverse is embossed a five-pointed star and on its reverse is the Indian state emblem and the inscription embossed along the upper rim. The riband is of gold colour with one dark blue stripe down the centre dividing it into two equal parts. If a recipient of the medal is subsequently awarded the medal again, every such further award shall be recognized by a bar to be attached to the riband by which the medal is suspended. For every such bar, a miniature insignia of a pattern approved by the Government shall be added to the riband when worn alone.
