was founded in 1854 by the brothers Richard Thomas and
Joseph Jump who had both been apprenticed to and worked
for B.L. Vulliamy. A 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 humpback bracket
clocks similar to those of Breguet, and were also responsible
for the overhauling and recasing of the astronomical
clock by Samuel Watson in the Royal collections. Silver
humpback carriage clocks were introduced
by Breguet circa 1813.
Breguets lifetime only a few were made; they are
among the best and the most expensive - he ever
produced. The humpback model has been very popular,
its shape being used not only by the house of Breguet
but by others such as Cole and Jump in England, for
instance, for two hundred years after its creation.
Toward the end of the 19th century in England, James
Jump made a few silver carriage clocks in the humpback
style. Today they are among the most sought-after by
collectors, along with those made by Breguet. James
Fergusson Cole also made a few. The clocks made by both
Jump and Cole are very rare and on a par with those
produced by Breguet.
