I bought this case (https://www.aliexpress.com/item/1005008677161841.html?spm=a2g0o.order\_list.order\_list\_main.53.5e821802TuZDIt) but selected the 'ETA2824/PT5000' option instead of the NH35/36 option.

Is there anything I can do if I want to use a NH35? It came with a white spacer ring if that helps. Is that some sort of converter for NH <> ETA/PT? or is it a spacer ring that is designed to specifically fit the movement it was bought for?
