From John Docktor, June 1, 2017:

I was in the Calouste Gulbenkian Museum in Lisbon, Portugal, at 12:30 PM when I heard a series of chimes in an exhibition room. My search for the source of the chimes led me to a circa 1760-70 globe clock made in Paris.   I did not have a ruler but I estimate the globe diameter as being 10 inches. I was surprised that this 250 year old globe clock still works.
