This is a c.1910 premier league silver-plated Arts and Crafts hammered copper mantel clock, the iconic design attributed to George Walton of the Glasgow School.
The delicate silvered case has a riveted flat top, domed in the centre. The clock dial is framed with a typically-styled Arts & Crafts tree, the polished form in relief to the hammered background. Eight riveted columns raise the case by around two inches, each finished in a leaf.
The fully overhauled French drum clock movement retains its original lever platform escapement, and is rear-wound, with a duration of 8 days.
The 3 1/4-inch white enamel convex dial is signed for the original retailer Penlington & Batty, Liverpool, who were watch and chronometer makers of repute, and indeed were makers to the Admiralty.
George Walton(1867-1933) was influenced by William Morris, and worked alongside Mackintosh, fellow alumnus of the Glasgow School. He is reputed to have designed a similar clock for Goodyers of Regent St, London.
