There’s a couple across the street from us, and they collect grandfather clocks of all types.  They have several that are well over 100 years old, and I think one that’s close to 200 years old.  It’s fascinating to hear the history behind some of them, and how they came to own them.
We had a grandfather clock in our house while I was growing up.  No minhag, just my parents liked how it looked.  I used to love watching the clock technician work when he came once a year to maintain it.
