Stjärnsunds manufakturverk



Stjärnsunds manufakturverk was a Swedish mechanical manufacturing company, most known for its production of clocks. It was founded in 1700, in the town Stjärnsund near Hedemora, by inventor and industrialist Christopher Polhem (né Polhammar).

Today, there is a company named Stiernsunds-ur which produces clocks according to Polhem's design, and performs repairs and maintenance on the originals.
