I was gifted a petite old Wakmann watch by my great-aunt, but unfortunately I have no idea what model it is, and I was hoping that someone on here might know. The face says Wakmann, 17 jewels, Incabloc and at the bottom what looks like France? (the font is tiny and I'm having trouble reading it). The back only says Base Metal Bezel and Stainless Steel Back. I can't see any serial numbers anywhere and I don't think I can open it :/ Thanks in advance!
