Seiko 6139 Service Tutorial Part 1 - Disassembly of The Calendar Works

Hello, This is episode one in series covering the disassembly & then the assembly of a iconic vintage Seiko movement 6139. This video is on the 6139B version but don't worry if you have a 6139A you can still follow along as there is only a very slight difference.
This first episode I will remove the movement from the case, remove the hands and dial and all of the calendar & motion works right back to the main plate.
I do find some problems along the way which shows that some watches are full of surprises!
