Santiago James Moore French, Royal Exchange, London, a fine watchmaker with examples of his work in most Museum collections around the world, known to have been the main early retailer of Westfield’s Patent watches – see the important article on these watches by Paul Tuck in Antiquarian Horology, December 2001.
Robert Westfield, 14 St James’s Street, Clerkenwell, Patent 3732, August 1813: the use of an escape wheel with teeth set at “different altitudes” (heights), thus spreading the wear on the steel cylinder. NB: Examples are very rare, with less than ten examples recorded, of which most are movements. This is the earliest known example which is engraved “Westfield’s Patent 2” under the foot of the escape potence, the name being now partly obliterated, possibly when the escape wheel was changed.
Lacking brass-edge, dial, hands and motion work, also noting the changed escape wheel. Otherwise complete and rather dirty, but will tick sluggishly if wound.
