A black 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 won’t hear any ticking but if your hearing is particularly sensitive in a completely silent room you may hear a very quiet whirring.
