The present lot comprises of several notably rare features; its filigree case, seldom found on English watch cases, the dial maker’s stamp on the dial’s underside, the lack of quarter division, and the early use of a balance spring. Jonathan Puller (1662-1707) began his career apprenticed to Nicholas Coxeter in August 1676, before moving onto John Miller. Puller became free of the Clockmakers’ Company in 1683 and went on to have eight apprentices of his own. He was assistant to the Clockmakers’ Company in 1701.
