I recently acquire a used Chopard Mille Miglia (16/8331-99) and its my first 'nice' watch.
It looks great and is running fine, but I have no idea if the previous owner ever serviced it. Assuming he did not, how often do these watches need to be cleaned/lubricated/etc? Should I only take it (or mail it) to a chopard dealer? What should I expect it to cost, etc?
Any advice would be greatly appreciated. I want to make sure I take care of it.
