Only one alarm clock

On my brother's Blip from a few days ago he showed a part of his collection with alarmclocks.
That picture gave me the idea to publish my collection (I have only one alarmclock). I saw this clock on a flee market for many years ago and it was love at first sight. I bought this clock but never expanded my collection.

My grandfather was a clockmaker and he stopped his business in the early 60's of the previous century. Though I was a little girl than I remember very little anyway.
