Hi ! Greetings from Melbourne, Australia. My son was recently given this great watch which was never used (Plastic is still stuck on the back) The first time he wore it the the glass face and ring which held it in fell off without him noticing. I was wondering if anyone could offer any advice on where I could possible get this repaired. Watch specs are: Swiss made circa late 1950s early 1960s The brand is Silver It says 17 rubis Ferrotex automatique on the face Face is 3 cm in diameter
