My 3717 is with him since late July.
I had an email from him 2 days ago saying that he had some kind of an accident (felt down or something) and that has hold him back from the day to day business.
He said he will sort out things soon.
... so far I maintain confidence to him.
PS: I personally wouldn't count fot the 10 days fix. More likely will be several weeks. Watch fixes take a lot of time (..... lack of spare parts , purely manual job etc...)
