Hi all, many thanks for the replies. I should say right away that I know nothing about watches. I have decided to repair and restore this watch but I will be teaching myself using YouTube and any cheap watches I can find that are similar in design to my Ambassador. Once I feel ready I will tackle the Ambassador. My partners uncle never used the watch as it was broken and he had no emotional attachment to it other than the thrill of finding a hidden gem, so I have decided to restore it to its original state.
The watch winds and works but the hour and second hands cannot be set. They engage on the first few turns of the crown but then the friction is lost and the crown turns without moving the hands. You can feel something trying to turn the hands and then it becomes totally frictionless. Cannon pinion perhaps?
I will try to post some images showing exactly what I’m referring to when I talk about clamps and screws. If anyone wants to see the video I was referring to, the link is below and shows exactly the clamps and screws in question.
