The only movement I have seen with a regulator and at the same time counter weights on the balance rim.
(But to be boring accurate, with a regulator it is not free sprung)
You took the words out of my [keyboard].
It’s rare to see a free sprung balance spring with weight-adjustment AND a swan neck regulator. Is the swan neck regulator just for show (and what a show this one carries out😍😍😍), or does it add to the isochronism and accuracy?
It's for beat error adjustment only...not like a traditional swan-neck regulator function
Here's a good write up about it, www.watchprosite.com musingsofawatchaddict.wordpress.com
I stand corrected.
And I have learned something new today. (Now I know something I bet the majority of my colleagues do not know). Thanks a lot for enlightening me.
