Spacer ring not tight enough, please help!

[Dani Cica]

I've got a rep with 2836 movement but whenever I pull out the crown to adjust time the movement moves a bit inside the case. I have opened the case and tightened the clamp screws but it's no use, the movement ring is still not tight enough with the case. I am sure there's a workaround for this issue without having to try another ring (which would probably be the same)...

Any suggestions?

Call it the Alaskan Backwoods Delicate Adjustment Tweak:

 

Squeeze the movement ring to make it slightly oblong in the axis where the stem penetrates the case.

this is likely because your movement tabs aren't securing your movement tightly and properly.

i assume this is for a franken datejust build? If so, then modifying the correct movement tab is the only way to go (i.e. take a longer tab and cut it to the right length and/or bend the tab so that the tab can secure the movement on both ends). I had this problem too when i built my first datejust franken using a 2836-2 case and 2836-2 movement

You can also cut little thin "shims" from paper or thin plastic and insert them between ring and case to get a good snug fit.

Make the tabs slightly longer. That will stop any movement

Thanks, already worked out!
