The story of Metrawatt AG began in Nuremberg, Germany 1933, when Dr. Siegfried Guggenheimer AG (originally founded 1906) was ordered by German government to change its name. At the same time the name of Metrophot light meter, previously manufactured by Guggenheimer, was changed to Metraphot.
Metrawatt continued developing and manufacturing light meters for three decades. Those included Tempiphot - the first selenium light meter with booster cell attachment, successful series of Horvex meters, and several models made exclusively for Leica cameras.
Metrawatt was later merged with BBC and ASEA, and finally with Gossen in 1993, forming the present Gossen-Metrawatt.
