Nice British pair cased watch from middle XVIII century.
Diameter of the outer case is 47mm, inner case is 40mm.
The watch is a quality piece.
The movement is equipped with cylinder escapement, a high-end feature for middle of XVIII century, used primarily by best London watchmakers this time.
It also feature half quarter repeater, striking 1/8 hour.
Movement is nicely finished, it has diamond endstone, pierced and engraved balance bridge with grotesque mask, steel balance wheel, round pillars.
While cylinder escapement is less depends on mainspring force variations, watch still equipped with fusee and chain.
Good example of British watchmaking skills from mid-XVIII century.
Benjamin Gray (1676-1764), fine watchmaker, was clockmaker to King George II since 1744. Since 1730s he works together with Justin Vulliamy (very fine maker according Baillie), who emigrated from Switzerland, and at some point married Gray’s daughter.
Son of Justin Vulliamy, Benjamin Vulliamy also became eminent watchmaker.
Condition
Watch appears to be in very good condition.
Movement is in running condition, though I don't guarantee time keeping.
1/8 repetition works as it should.
Dial has very minor wear, very nice condition.
Beautiful golden beetle & poker hands, mineral bull eye glass.
Plain silver case is probably later, it's equally in good condition, with some period wear.
