Replacing a rub-in jewel hole
PLEASE NOTE: This is a video meant for entertainment purposes only – it should not be considered part of our watch repair course.
The balance on this vintage pocket watch movement has a rather large amount of side shake and low amount of amplitude and upon investigation I found that the jewel hole on the balance cock is damaged. This is a rub-in style of jewel and a new one will need to be fitted using specialist tools for the purpose.
