M Mantel Clock Posh GreyNewgate M Mantel Clock Posh Grey A contemporary grey 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 won't hear any ticking but if your hearing is particularly sensitive in a completely silent room you may hear a very quiet whirring.
