This video is to show a particular case, when automatic mechanical watch, based on the Seagull TY2723/ST1771 movement, doesn't run even with a mainspring being totally wound up. The video shows how a partial disassembling can release an over tighten click spring, that prevented a mainspring from unwinding. The same problem can occur in other automatic mechanical watches using the same design.
Thank you for watching and please do not forget to give me a thumbs up!
