Joseph Sewill was a maker to the Admiralty and the Royal Navy. He was awarded a Prize Medal at the 1862 International Exhibition. He invented and patented his own auxiliary compensation balance. In 1874 he won the Greenwich Observatory Chronometer Contest. Most of his chronometers are two-day chronometers. He used ebauches by Kullberg, Mercer, Poole, Murray. The present one is by Mercer.
