Cool video (29minutes) showing the disassemble of a Miota and a Swiss caliber: The watchmaker goes step by step describing the parts and their function.
Yep, at 24m46s it is visible at lower left: 2824-2. Nice article about it: https://wornandwound.com/caliber-spec-eta-2824-automatic-people/
Very interesting. Thanks for sharing the video. I wonder how some of the Russian movements differ from the Japanese and Swiss ones.
