Gruen

The Gruen Watch Company was a prominent American watch manufacturer, founded in 1874, known for combining American case design with high-quality Swiss movements produced in its own factory in Biel/Bienne. The brand was particularly famous during the first half of the 20th century for its innovative and stylish designs, such as the ergonomic Curvex and the ultra-slim Veri-Thin models. Although the original company ceased operations in 1977, vintage Gruen watches are valued by collectors for their historical significance and distinctive aesthetics.
