Get a thin sheet of brass and cut a dial. Center drill, clamp to movement and mark on back through dial post holes and solder new posts on if possible.
Get it sand blasted and then PVD coated to give it a matte black finish
Hands. Take to a jeweler and ask about rhodium plating to match numbered insert (may need this to be plated also)
I'm curious on how your going to affix the numbered ring to the back dial? Maybe two tiny screws on the outside rim
To be honest. Hands are not long enough. Minute hand actually smaller than hour hand
As mentioned. I have 90 and 180, so not sure if you can ream the extra .5 out of them. There's also the length (maybe too long), but might have 17, 18 and 19 ligne
