Who manufactures gruen watches?
The final incarnation of the original Gruen Watch Company folded in 1977. Rights to the Gruen name were sold to M.Z. Berger, so watches branded as Gruen are still occasionally manufactured. As of January 2010, however, M.Z. Berger did not list Gruen as one of its brands on its corporate website.Source:The Gruen Watch CompanyThe Watch Guy: Gruen Watch CompanyM.Z.
