I have the same Problem with my last order. I chosen that the risk to send the watch back to china, was for me to dangerous and otherwise you need to know that this action will take some time.
It' s a long way from germany to china.
I send my watch for a complete revision and to fix a problem to domenico.
The revision service from domi is the first think that i make for all my watches. He opens the watch, clean and oil the movement this increases the lifetime of the watch.
