Cases, keys and accessories

Clock and watch cases protect the movement and express taste and status. Watch cases were made by separate specialist case-makers whose marks, along with assay hallmarks, help to date and place them. Clock cases were the work of cabinet-makers, bronze founders, ceramic factories and silversmiths, so they belong as much to the history of decorative arts as to horology.

Keys, chatelaines, watch stands, watch papers and winding tools are part of the material culture of timekeeping: they show how timepieces were worn, displayed, wound and maintained.
