Notes

Note: The appearance of this watch is characteristic of Jump's style. 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 clock-maker'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 docks, many of them in the style of Breguet. From at least 1883, they made a number of archtopped bracket clocks ('humpbacks') similar to those of Breguet, and were also responsible for the overhauling and recasing of the astronomical dock by Samuel Watson in the Royal collections.
