Movie Makers' Clapperboard Metal Clock

A clapperboard is a device used in filmmaking and video production to assist in synchronizing of picture and sound, and to designate and mark the various scenes and takes as they are filmed and audio-recorded. But this item isn't thast. It's clock. But the 'clap' works!
A must for movie buffs. The clock is made of metal and glass. The mechanical part is plastic and takes an AA battery.
