Hi,
I know him since 2010. I bought some wacthes from him, he repaired others, lumed some, AR coated a few and I was always very happy with the service.
Last week I visited him and saw how much work to do he has. You need to be patient as he is more or less the only one in EU.
He is reliable and not the fastest, but does a very good job.
From my experience. NO WORRIES!
