Title: Red Alarm Clock Jigsaw Puzzle
About: Designed to make a sound at a specific time the alarm clock's primary utility of these clocks is to awaken people from their night's sleep or short naps. Traditional mechanical alarm clocks, like the red one in today's new jigsaw puzzle, have one or two bells that ring by means of a mainspring that powers a gear to propel a hammer back and forth between the two bells. User-settable mechanical alarm clocks date back at least to 15th-century Europe.
