I purchased this from an antique shop on August 11, 2011. It came with case and guarantee papers. The triangle on the movement means 1926-35-or 45, I take it but when I try to put in 26 the site won't take it, so I take it is 1935. Gemex made bracelet. I think she is a real beauty. I may have the dial redone, but I have not made up my mind yet. Anyone know where to get the crystal?
