You would treat this build like you would a MyManMatt Datejust build - Raffles movement ring #2
Stem height is perfect.
If you use a JMB 16200, 2824 slim case, it already comes with the movement ring.
It's a rep bracelet. I totally forgot the source but from what I remember, it was spot on.
Franken 14270 is a lot cheaper than any gen I know of. If you can find a all gen 1500 for under $1000, I'd jump on that.
For my next build, I am tempted to have JMB engrave 14270 between the lugs...
