Thankyou again.
The reason I want to find out about it is it belonged to my Dad. It was a gift to him from my late Nan in 1963 this is engraved on the caseback. Unsure why only Nan as my late Grandad was still alive then!! Sat in a cupboard for years. My big brother was then given the watch a couple of years ago after he asked if he could have it. Which was strange, as I had told him I was going to ask!!
Then on Xmas day my big brother gave it to me, as I have had a very tough year.
Will check out that thread and maybe ask Steve Harris.
