Cool idea about thinning the case, I noticed my spring bars dont poke all the way through the lug holes.
You have certainly put some real effort into that piece.
I totally agree with the modern serviced look, particularly due to the shortage of a decent 14060m rep. I intended to go the same way with mine, but I got hold if a gen gloss dial with tritium so I'll use that for now, it is accurate for my l series too.
Good luck with the 1680, I love their service disks with the nice White markers.
