Thanks Dan. Much appreciated. I look forward to your PM and to having Grandad's watch working again :-)

He always made me smile in many ways but the watch really tickled me as a young man. He was so amazed at such a clever thing as a self winding watch that he spent far longer moving his arm up and down than he ever would have winding a traditional watch! He would have loved the internet
and when I think of how interested he would have been at it I still miss him. But with fond memories :-)

It was either loosing or gaining, can't remember which, and I tried to adjust it. Unfortunately I caught a hair spring with my screwdriver and made it worse by trying to put it back. Needless to say, it never worked again :-(

Out of interest, the other watch I hold dear is my late step-Dad's gold Cyma. That had a crack down the back and a local jeweler did what was required to fix it. Seems OK but I am reluctant to wear it on all but special occasions. No idea of the worth or rarity but, whatever it is, it will stay with me till I shuffle off this mortal coil!
