Distribution of time by the Belvilles

Prior to Airy’s arrival as Astronomer Royal in 1835, some of the London watch makers such as Arnold and Vulliamy would send a member of staff to the Observatory every week with a good quality watch to establish the difference between the time it showed and the true time as measured with the instruments at Greenwich. Once the error was known, the other clocks and watches at the watch maker’s premises could be set to the right time. Concerned at the amount of time that was being wasted servicing these requests, Airy restricted such visits to Mondays. By 1840, instead of the watch makers sending someone to Greenwich, the Observatory’s Second Assistant, John Henry Belville (1795?–1856) was visiting them instead, carrying the time on a pocket chronometer made by John Arnold and charging a small fee for his service.

In 1852, when time signals began to be distributed from Greenwich via the electric telegraph, there was still a demand from watchmakers and others for Belville’s service, so it continued. When he died, in 1856, on discovering that she was not eligible for a widow’s pension, Maria (1811/1812–1899) asked Airy if she might continue the service in her late husband’s place. Her request was granted. When in 1892 she became too old to carry on, her daughter Ruth (1854–1943) was allowed to continue in her place. In an interview in 1908 she described a routine that involved checking her chronometer at Greenwich every Monday and visiting, at least once every two weeks, some forty customers in the London area. The service was continued by Ruth well into her 80s and finally came to an end during the Second World War, probably in the autumn of 1940.

Originally made for the Duke of Sussex, the chronometer by Arnold became known as ‘Arnold-345’ or more affectionately just as Arnold.
