Is the cal. 350 back wind a good investment? Was this movement made by Lecoultre? Thanks for any information that can be provided. I understand there were 2 models. 2nd model was an improved updated movement.
I have a 350 backwind (first edition ) and there is little to no material left for servicing even by Patek. I upgraded the movement years ago but I don't wear it do the issues the movement has in regards to winding . I saved a grand doing the work myself but still sent $645 on parts .I would not do it again .
