I think you are confused about what this is. These should be basic questions about the venue, like hours of operation and what it is like. Just because I have been to the museum and liked it doesn't mean that I am an expert on every clock ever made. Google is your friend. Look up a local clock and watch shops. That would get way better results than asking people who have visited a museum.
AGREE, give them a try.
I'm sure the National Clock and Watch Museum can answer your question.
