Benjamin Gray & Justin Vulliamy, No. ois, London, 1745

Description: Gilt brass cylinder movement (36mm diameter), brass escape, Graham-type banking. Square baluster pillars, steel balance and spiral balance spring. Original gold dial, enamelled using ‘venetian’ enamel, which requires more heat when fired than conventional enamel (as used by George Graham). Materials used for making dials other than gold would not withstand these high temperatures. Black Roman and Arabic numerals with dots within the minute track, typical for the Gray/Vulliamy production. (A)
