This Acctim Silicone Pale Green Clock, features a soft silicone case and a large digital display, which lights up at the touch of a button. It is just as easily viewed at night as it has Smartlite® technology, where a bright green backlight illuminates the display as the room gets darker and turns it off again during the daytime to prolong the battery life. Dimensions: L5cm x W14cm x H6.9cm.
