Any Omega 1481/Tissot 2481 keyless works experts?

I'm about to tear my Tissot 2481 apart to try and repair the disfunctional keyless works. There are quite a few photos and videos available but they show conflicting information regarding the positioning of the keyless works yoke spring. The 2 photos below show the locations (but are 180 degree views of each other). One shows that the round end of the yoke spring around a stud that the setting lever spring (the odd shaped plate that mounts on top of the yoke spring) mounts onto. The other photo shows the round end of the yoke spring positioned to the side of that and around a hole. I've seen maybe a dozen depictions of these and about half show them one way and half show the other. Not only that, but the springs here are laid in on opposite sides. One has the spring laid in with the bent ends facing away from the yoke while the other shows it laid in with the bent ends toward the yoke. Only when the spring is mounted around the stud have I seen springs laid on alternate sides. If the spring is mounted around the hole it's always laid with the bent ends facing toward the yoke, which looks intuitive when you consider the potential contact points with the spring installed the other way.

Which one is correct? It seems that these movements all functioned properly after servicing, so perhaps any way works. It does seem, though, that mounting the spring around the stud would result in stronger spring tension against the yoke. Thoughts anyone?

I've found an Omega technical guide for this movement and a drawing in it would also corroborate that. There are cutaways so you can spot the spring in the dark gray area coming out above the large screw at the lower middle of the diagram. Having seen actual photos of movements with a similar point of view, this is where the spring would be if it were mounted around the stud. You can see that the hole where it alternatively could've been set around is above the number 23 on the date wheel. It's obviously not mounted there. Also, a bent end can be seen pointing away from the yoke, or actually parallel to it in the diagram....but not pointing towards it.

Still, if anyone has any info to add then please do.

Thank you for clearing that up! I'm intending to repair a 2481 watch I recently picked up with very problematic crown action, so I've been researching this before getting into it. I'm a novice, but I see a few videos by seemingly pros, or advanced amateurs, and some of them have this wrong. My movement looks pristine before tearing into it, so hopefully the issue is just in the keyless works.

One thing I know, with photos and instructions as clear as this, the yoke spring will be installed correctly! Very much appreciated.
