Ubi,
The thing that I LOVE the most out of these two builds, is how understated they are. Simple, functional and functionally gorgeous watches. These are two of my favorite watches and anyone should be happy to just have these two(well, almost everyone except for LHOOQ ) and perhaps a Snowflake
As far as patina goes, well these two are embarking into a glorious path as it stands,so no doubt they will look better and better(if that is possible) as time goes by.
I have a few casebacks at home I can take pictures of see if they are what you need. I know you probably have parts, but If you could use one...The inside stamping may be something else, but I will definitely let you know and send pics.
