Servicing an automatic Doxa can be costly. I know that for the most part most of our Doxa’s are only a few years old. But, I recently purchased a 300T Reissue and it is around servicing time. So I ask should I send it back for servicing or wait until a problem occurs? :oops:
I can say that it currently gains 3 seconds a day. This is well within COSC specs.
