A Gruen ladies' tonneau-shaped watch from the 1930s, famous for its Curvex (driving) style. The 10KGF gold case (15mm x 27mm), reflecting the Art Deco style that was a major trend at the time, is paired with a dial and yellow celluloid crystal that are also fitting for the era, creating an atmosphere of the period. Gruen was a historic watchmaker, ranking among 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. Many variations were released for men, and also for women. This watch is from the time when the Curvex was first introduced, and its calm design is its charm. (※) When choosing gold accessories, you'll often see the markings "GP (gold plated)" and "GF (gold filled)". Although the names are similar, the amount of gold used differs. Gold plated is gold plating, meaning it is thinly coated with gold. In contrast, gold filled has about 100 times the thickness of gold as gold plated. It rarely peels off to reveal the base metal. Operation has been confirmed. It runs for a full day with an error of about ±10 minutes, which is a good condition, but we do not accept claims or returns regarding the mechanism to prevent troubles such as swapping. We recommend having it overhauled if you plan to use it for a long time. Antique watches can seem daunting, but watches in this price range can be used normally in everyday life without overthinking it. It's a lot of fun to wind the watch you've decided to wear for the day and start your 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 #AntiqueClock #VintageClock #Antique #OldTools
