This is a pretty item with chased case, enamel dial and gold hands.
It is marked 925 with an acorn for Chester and the sponsor’s initials AGR for the importer Robert Pringle. There is an interesting article about this online.
The inside of the case bears the inscription “West Sussex County Council for Five Years Perfect Attendance 1910”
There is a small chip on the edge of the dial and the front of the case has a weak snap fastener.
