Finding an intact and complete original Jones pocket watch is a rarity. Alan
Myers estimates that no more than 2 percent of the about 26.000 watches made,
have survived . Of these, only a small minority are original and cased in the
authentic case almost 150 years ago. The early cases of the highest quality
'E' and 'H' movements were made of 18 and sometimes 14 kt gold. The first
about 15.000 movements were all exported to the USA. Here they were cased in
engine turned cases. Jones considered the casing in America more efficient and
cheap. However, many cases have been removed for their scrap gold value, also
taking in mind that the Schaffhausen watches were not considered to be
collector items until 1980. In the US were several factoriesonly making
pocket watch cases. Among them were Keystone, Dueber, Wadsworth, Jas.Boss,
Brooklyn Watch Case Company to mention a few. Casing a Jones movement in the
US was extra difficult as the Americans used standard sizes for their own
watch production of which the brands Waltham and Elgin were the largests. The
Schaffhausen Jones movements measured 43,3 and 43,7mm and were too small for
a 18 size case and too big for a 16 size.Therefore every Jones case had to be
custom made to gurantee an optimal fit.
