Let me add a view from a Munich local. I have been to his store often and he and his team repaired a lot of my vintage watches. The quality of services received is excellent and these guys really know what they do. Their services have become a bit expensive over the years but it is still ok. The store is located in the centre of Munich in a beautiful side street (just behind the famous Bayerische Hof Hotel) and he enjoys a very good reputation in the local market here as a reliable and trustful watch dealer.
