Hi all, I have owned a Seiko Calculator for quite some time but have decided to complete the look with an aftermarket plastic cursor ring. I have read, and from trial and error have deduced, that you need to remove the bezel to install the ring.
I have removed and replaced 6139 bezels (case-knife off case-press on) can anyone tell me if this is the same process as I would rather not ruin it?

Thank you for any help or advice you can offer.
