Notes

Jump Firm founded in 1854 by the brothers Richard Thomas and Joseph Jump who had both been apprenticed to (respectively in 1825 and 1827), and worked for B.L. Vulliamy. Richard Thomas was the inventor of the clockmaker's sector, a proportional gauge chiefly used for wheels and pinions. An ornament of Bond Street, through several generations, the firm made a wide variety of clocks, many of them in the style of Breguet. From at least 1883, they made a number of arch topped carriage clocks (humpbacks) similar to those of Breguet, and where also responsible for the overhauling and recasing of the astronomical clock by Samuel Watson in the Royal Collection.
