Can someone please give me any info about this watch? From what I understand my Grandpa bought it for my Grandma in Germany while he was stationed there. The front face says Stowa on the top and 17 Rubis on the bottom. The back says Lunette, Walz Gold Double, 20 Mikron, then it has a G, a little star with a little line under it, and a K, and then Boden Edelstahl and the very bottom line says 4566. I can upload pictures if needed. I cant find anything with the word Lunette or the G and K with the little symbol between them. Thanks in advance!
