David......thankyou so much for that. I can see now the 09935 that is stamped on the case means 935 standard silver from Switzerland. I am guessing this was my partners grandmothers watch as I said, so 1887 - 1907 would be a reasonable timeframe, as she would have been born 1900 +-10yrs at a guess.
I looked on the watch bow and can see 2 stamps as shown in your post but couldn't see the third stamp on the winder although there IS a mark but it's very hard to see if it is an actual hallmark stamp.
I wound the watch after reading your post and was very pleased to hear it ticking. My M-in-L said it worked. She was right. I hope to take it to the repairers I have found next week for a quote. I spoke to one of the repairers on the phone and am more hopeful now that it can be fixed. I just think it is too nice NOT to fix it and I'd love to be able to wear it around my neck.
OK...I am happy to take some more shots of the movement if you think there is possibly a makers mark on it but to be honest I cannot see anything when I look at it with my magnifying glass
Thankyou, thankyou, thankyou again

You've made me much happier about this watch now
