Help: Unknown watch parts - 3 types?

[pockwatch]

Hi, friends, from what type watches are these parts if you know please? Approx. length is 7.5/8 mm. Thank you.

I could be wrong, but it looks like a central-seconds watch, with its central pinion axle and spring.

I'll second that. Centre seconds pinion from an indirect driven centre seconds movement along with two variations on the theme of anti-stutter (don't know the correct term) spring.

From what watches can be this items please if known - because I have thousands of them - the same items as per pictures?

I rather imagine you'd need to measure them for us to have even a hope of pointing you in the right direction; without scale, we can't even guess at what size of movement is involved.
