Trying to FIX a Faulty Pulsar Chronograph Quartz Watch

Hi, in this 'trying to fix' video I attempt to repair a Pulsar Chronograph quartz watch. The movement is a 7T62A and is made by Seiko. The original fault was that the watch would stop, the stopwatch did not center at 12 (0 seconds) and the date would not change over at midnight (or at any time).
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.
