Broken Rotor

[Tkenyo]

hey RWI, I quite new to watches so there might be some poor terminology. I have a JF AP with a A3120 movement which I believe is glorified miyota - not entirely sure. Anyways, the rotor came loose the other day and when ever I put it back in it comes back out, Ive given up so I've come to the best source I know. The question is, how do i put the rotor back in?

Please refer to video.

Yes that is what I though at first, but it appears there is no screws as there is no female end where they connect.

Unless I am sorely mistaken, the rotor press fits to the spindle. Sit it evenly on the spindle, then press it on using even pressure. I've had them come off before on other watches. No big deal.

you're amazing, the depression from the top of the rotor the bottom meant it was offline and wouldn't go in, thank you for the advice.

Really hate what JF has done to the movement. The rotor isnt the original rotor. Since JF has made a decorated plate that just sits over the original movement they have also made their own rotor that is much thinner and about one gram lighter than the original rotor. Its pressure fitted, noiay and comes off extreamly easy. Sometimes you can put it back on with some pressure. Sometimes your fucked. Looks is definitly not worth it...
