This is an antique Gruen watch. I believe it was manufactured in the 1940s. The model is a Curvex, and the movement is Cal. 370. Curvex watches with the 370 movement are becoming rare, so I think this is a valuable piece. It runs with an accuracy of about one minute per day. I am selling it because I don't have the opportunity to use it. There are scratches overall, so please check the photos. It's a size that can be worn by both men and women, so how about it as your first antique watch? ◯ Brand Gruen ◯ Case Length: Approximately 42mm Width: Approximately 24mm Lug width: 16mm (Including lugs and crown) Material: 10K gold-filled case ◯ Movement Manual winding Cal. 370
