This is a ladies' Gruen Precision series watch, very famous for its Curvex (driving) style. Gruen was a historic watchmaker, one of the top three in America, and held a large share of the ladies' watch market in the 1920s. Later, in the 1930s, the GRUEN-CURVEX solidified its position as a top brand. This Precision was a general-purpose brand supporting the two major series, Curvex and Veri-Thin, and was worn by many American women. The 10KGP gold case (15mm x 25mm) with an Art Deco design from the 1920s, and the chain belt (which is also wonderful), are truly atmospheric and beyond reproach. There are fine scratches on the crystal, but I don't think there are any problems with use. I checked the operation, but it is almost not running. We do not accept claims or returns regarding the mechanism to prevent troubles such as swapping. If you intend to use it, we recommend having it overhauled once. Antique watches can seem daunting, but watches in this price range can be used normally in everyday life without thinking too hard. It's a lot of fun to wind the watch you decided to wear today and start the day, and above all, you don't have to experience the sadness of finding it dead when you try to use it after a long time. Once you use a mechanical watch, you can't go back to battery-powered ones. #antiquewatch #vintagewatch #antiquewatch #vintagewatch #antique #oldtools
