The clock was made in the early/mid 1950's with a 1930's art deco look. Apparently,there was an art deco revival in the 1950's. I let it run down sometimes just to let me have a break from the loud 'boings'/chimes. A midday or midnight 12 'boing' chime takes approximately 1 minute 10 seconds. Bloody annoying when you're trying to talk to someone on the phone,or listen to summat on the radio!!
Edit....Just remembered. To have less decibels you can move the little hammer in the back/mechanism slightly,so that it doesn't completely hit the coiled spring type thing that makes the 'boings'.
