Radio controlled mantle clock. A beautiful combination of radio controlled technology & heritage styling, our chiming clock is crafted chiefly from solid oak. Accurate to within one second in 60 million years, it automatically receives its signal from the National Physical Laboratory in Cumbria so you never to need to adjust or reset it. No winding is required & its chime, which starts at 6am & finishes at 10pm, is powered by 3 x AAA batteries.
