Railway Mantel Clock Posh GreyNewgate Railway Mantel Clock Posh Grey A station style mantel clock with a bold marker dial, red spade and baton hands in a matt grey finish. 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. Material: Acrylic, Paper, Metal Hands, Glass Colour: Grey
