The Westclox Big Ben wakes heavy sleepers with a loud mechanical twin-bell · an all-analog face with luminous hands and a press-the-lens dial light.
What the specs tell you
A genuinely loud twin-bell ring. A mini-hammer strikes the two metal bells, the kind of old-school ring owners buy specifically to get heavy sleepers up. The face is analog with hands, no digital display.
Set on the back, lit on demand. Rear knobs set the time and alarm and a rear switch arms it; pressing the front lens lights the dial. Luminous hands handle the rest at night.
Runs on one AA. A single AA powers the movement, bell, and light. The manual notes the glass lens doubles as the light button, so a cracked lens is the part to replace.
