Big Ben

BIG BEN is the first and only alarm sold exclusively to jewelers. He is without exception the finest sleepmeter made—the best looking, the best built, the best running.

Big Ben is a beautiful thin model alarm clock standing 7 inches tall and mounted in a reinforced triple plated case. He is fitted with big strong easy winding keys, clean cut heavy hands and a large open winsome dial, distinctly visible across the largest room.

Big Ben rings just when you want and either way you want, intermittently for fifteen minutes, continuously for ten, and he rings with a jolly full-tone ring that will arouse the drowsiest sleeper.
