As I only did a day-trip I can't really say that I explored much outside of the main museum. I understand that Girard Perregaux have a museum that is invitation-only and other manufacturers may offer the same. As you know, rail connections work very well in that part of the world and you could get to Bienne very easily. If you're passing by Bern I can give you a couple of tips.
I trust you've seen this thread?
