This could be a very interesting discussion, but it will be a long, very long one...
To make it short, when you have to service a movement whose even the smallest parts are delicately finished, and that the watchmaker or his company has disappeared.... Who will:
1/ Accept to service the Watch?
2/ Without fuxxxg the delciately finshed parts, like polished screws, and so on...
Then, how long will it take, when these small watchmakers ( in size not in talent ) are more busy to make watches ( which is normal and logic ) than repairing or maintaining them?
Nothing is perfect in the " Service World ", by far, even in the big Manufactures... But I still have questions about these Indepedants watches....
Best,
Nicolas
