Hello, my father received this Calatrava as engagement gift in the 60s, he has never serviced it and he only wears it like 2 or 3 times per year for special occasions.
I would appreciate a recommendation about how to service it and idea of the service price, I asume that doing it with PP service center will be quite expensive but not sure how risky would be to do it with an independent watchmaker.
Thank you!
