Newgate Theatre Mantel Clock StoneNewgate Theatre Mantel Clock Stone The Theatre Mantel Clock in Stone is a contemporary mantel or desk clock with a minimalist dial. Known as silent sweep in the industry, the hands move in a constant sweeping motion rather than a stepped tick. So you wont hear any ticking but if your hearing is particularly sensitive in a completely silent room you may hear a very quiet whirring. Ideal for adding style and function to the desk, mantelpiece or shelves,
