Arguably the finest chronometer maker of the second half of the 19th Century, Victor Kullberg was born on Gotland. He served his apprenticeship with an unknown clockmaker before working for the house of Jurgensen in Copenhagen. Impressed by the workmanship he saw at the Great Exhibition of 1851, he stayed in London. He submitted chronometers to the Greenwich time trials with great success. In 1862 he submitted two pieces, which came first and second out of eighty. In 1882 the Astronomer Royal's report to the Clockmakers' Company said of Kullberg's entry 'this was the finest chronometer they had ever had on trial'.
Kullberg exhibited all over the world. In 1868 he achieved gold medals at Havre and at the National Academy in Paris; and again in Naples in 1871 and Trieste in 1872. In 1874 he was appointed chronometer maker to Sweden and Norway and decorated with the order of Vasa.
