In excellent overall condition. This watch was probably made by Viner and retailed by Webster. Viner improved on a system invented by Joseph Berollas which used an chain and returned automatically. Although Viner's design requires the user to return button manually it is far more robust while at the same time less expensive to produce. An earlier patent, no.1970, was taken out by Robert Leslie in 1793 but was not adopted. Another patent, no 3854, was granted to Edward Massey in 1814, again not widely adopted. Although Viner produced these for a number of years, including variations with cylinder and lever escapements, few have survived. Casemaker Philbert Mathey, Clerkenwell.
