Olympic Swiss 17 Jewels Incabloc Ladies Vintage Wind up 。The 1940\'s Grewitt 17 Jewel Ladies Cocktail Watch is a rare vintage timepiece. I have not been able to find a description or match anywhere. Additionally I cannot find any marking on the watch itself. See pictures. Watch does keep time. This wristwatch features a classic design and an intricate 17-jewel movement, making it a unique and sought-after piece for collectors of vintage jewelry. With its retro style and feminine appeal, this cocktail watch is a timeless accessory that exudes elegance and sophistication.
