Gruen was a well-respected American watch brand known for its precision timepieces, particularly in the early to mid-20th century. The Conoruma line was part of Gruen’s offerings in the 1930s-1940s, featuring durable, gold-filled cases and manual-wind movements. This watch exemplifies the Art Deco and early mid-century design, with its rectangular shape and stepped case detailing. The 7-jewel movement was a standard for functional yet accessible watches of the time. Due to its age, this piece is likely sought after by collectors for restoration or parts, as vintage Gruen watches are increasingly scarce.
