Rolex calls it second wheel. ETA (and most ebauches) call it Sweep second fourth wheel. Watchmakers who don’t know exact part names call it center wheel (because it’s in the center).
Center wheel is the one right after the barrel. Rolex calls it great wheel. Watchmakers who don’t know proper name calls it Second wheel (because first wheel is the barrel, so this is the second, and so forth).
#224 = fourth wheel w/ second hand (offset, usually at 6 o clock)
#227 = s/s fourth wheel (with sweep second hand, in the center)
#201 = center wheel
#203 = offset center wheel
#206 = s/s center wheel
I am less familiar with what makes a center wheel offset, as it seems they are often not in the middle so naturally offset? But offset center wheels also come with a tiny canon pinion that is separate from the usual canon pinion(where you install the minute hand). 206 is when the center wheel is actually in the middle and needs to have a hole in the center for the s/s pinion (275) to go through. Naturally this set up uses 220.

I have a 6619 8230 sportsmatic which I'm restoring.
The stem will not go back in, it goes 30% and is blocked.
Why would this be?
And which side to I disassemble to resolve it, dial side?
Thanks for any advice.
Need help with my Willard 6105-8110 from 1976
The movement doesn't stops when I pull out the crown
It seems like that the hacking lever ist not installed (look through the inspection hole)
Can I use the lever from another movement - 6106A/B/C for example?
