I would like to replace a wrongly installed Buren cal 11 for the correct cal12 and wondered if these are easily transferable?
I’m hoping this is the case as I know some Carreras were produced using either
Any help appreciated

 

Hi Roger, yes there should be no issues switching them over as they are fundamentally the same movement. Cal.12s tend to be quite expensive these days if you can even find a loose one, unless you use a donor but that's more money still!
