Mystery Vintage Jaeger Le Coutlre Ladies Watch

Hi

Can anyone help or advise me the vintage of this watch. This belongs to my mum and I was told that my dad bought this for her as a wedding gift almost 50 years ago however, I have searched everywhere to get an idea of its vintage and true value.

Going to JLC is no use as they want to charge me Euro 350+ just to evaluate and I need to send it back to Belgium which I am not comfortable with...I know this is a very small watch and I really try to expand it further to give a better image but this is the best I can do....can anyone help?

Thanks
