Vintage silvertone Wyler ladies watch with Speidel expansion band. Marked Wyler Incaflex on the face, Stainless Steel Wyler Incaflex Waterproof 1758/7D 700M on the back of the case. The textured expansion band is marked Speidel and has the Pat No. 2689450 which dates the band to the 1950s. The watch runs great and keeps good time, but I have to admit I have no clue as to how to set the date. There is a fracture on crystal at the 6 hour. There is a slight kink or twist in one of the bracelet links - see picture, but this does not affect the look of the watch when worn. The face is intact but appears aged.
