Victor Kullberg 1824 -90 was one of the greatest chronometer makers of the second half of the nineteenth century. He made chronometers under is own name but also supplied movements to many other prominent chronometer retailers. One his finest inventions was his ‘flat rim’ balance, a very pleasing design but expensive to produce due to the constructional difficulties.
