Hi just acquired this Kienzle watch,not sure if it’s a men's or ladies watch. From the strap size and shape ladies I think ? The movement, cal. 48/15 (48 is the movement family, the 15 is the number of jewels I believe. The movement tells me it’s circa made after 1950. 1955 to 1959 would be a good guess. I think the main springs gone but before I embark on a strip down . I would be grateful for any advice on the cal etc as I’ve never come across this make/type before .
