Good morning all. My girlfriend was recently handed this beautiful, vintage ladies watch that used to belong to her great grandmother, and on her behalf I was wondering if there are any eagle-eyed folk who could possibly identify the make (without opening it up)? Approx 18mm case Blued hands Solid 9 carat gold bracelet with expanding links. Swiss Made on dial. No identifying features on caseback. Handwound All looks original Many thanks!
