Stylish & simple, with a matt black case this classic yet contemporary styled clock, features bright glow in the dark numbers & arms (except the seconds hand) allowing you to tell the time regardless of the time of day. It's a breeze to hang, the clock comes with a built-in keyhole hanger, so just hang from a nail or a screw. Another cool feature of this clock is the sweeping second h&, that has a silent operation, rather than a tick tock! These also look great in sensory rooms or rooms with UV lighting, as the glow in the dark details also fluoresce brightly under blacklight. Please note, this needs to be in a place that does get good light, things that are 'glow in the dark' do need to be charged via daylight or artificial light to work! Requires 1 x AA battery 25cm x 4cm Silent sweeping seconds hand
