Not the watch you will easily find, for sure. I don't know the expected value since I didn't ask when I took the picture. As for the crown, I have to investigate. [nt]
The Habrings used it in their initial Jumping Seconds model, prior to designing their own jumping seconds mechanism for their watches. Once we see pics from Nico, we can fins out for sure ;-) It's a neat complication and one of my favs. Cheers, Tim
