It"s an alarm clock with a shape that I designed, it sits slightly angled on an L shaped aluminum extrusion, with the clock face set into a round hole. A rocker-switch, to set the alarm on and off, rotates around the mechanism, which sticks out of the back, and a small window below the 12 marker on the clock face indicates its status. Movement: Quartz Material: Solid aluminum, scratch-resistant glass. Power: 3 IEC LR44 Watch Batteries (included). Snooze function: Alarm sound repeats every 5 minutes until 40 minutes of functioning. Dimensions: 3.5" wide, 4.25" high, 1.25" deep. Weight: 8 oz.
