Newgate Charlie Bell Echo Alarm Clock GreenAn 'Eden' Green Charlie Bell Alarm Clock with a colourful modern matt finish case, contemporary graphic dial and a moving hammer and twin bell alarm. 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 a pop of colour to the desk,
