Grandfather clock

A grandfather clock was a large clock that was approximately the height of an average human male. Its size meant that it had to rest on the floor, rather than upon a mantle piece or bookshelf. Its larger size meant that it had a much louder, deeper chime than the typical mantelpiece clock.

In the Edwardian house Edward Grove, the chimes of a grandfather clock could be heard every time the time loop started over again. (AUDIO: The Chimes of Midnight)
