Trying to FIX a Faulty 1980 Lady's Seiko Automatic Watch (2906 Movement)

Hi, in this video I attempt to repair a lady's watch from 1980 which has stopped working. It is a Seiko automatic watch (no battery in it so works from the movement of your body). It has a 2906 movement and it only works for a few seconds when it is shaken. Mike's helpful channel that I mentioned in the video is called: My Retro Watches :    / @myretrowatches   Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things. I do love fault finding and trying to fix broken things so I hope that comes across in this 'Trying to FIX' series. Many thanks, Vince.
