Where is Hölstein? 28 July 2023 12:50 Updated The beautiful village of Hölstein, our home since 1904, is in the Waldenburg Valley in the north-west of Switzerland, 35 km from Basel. Related articles I’m visiting Switzerland and I’d love to visit the Oris factory. Is this possible? Where are Oris watches made? How anti-magnetic are Calibre 400 Series movements? What do I do if my watch needs a repair service? I’d like to work with Oris as part of my studies/training. Is this possible?
