Step 13: The 6 o'clock sub dial mod
So the first step is to remove the plate on top of the movement (i.e. the one with the dial marker). There are 3 small screws to remove (so small I have lost one...).
To lift the top plate out just use the tiny screwdriver as a lever.
Then it gets tricky: you see that tiny wheel on top the picture ? It was put in place in the movement thanks to small machined hole.
Since to aligned it with V72 subdial hole it needs to be moved up by about 1/2 mm you will need to sand the back of the wheel.
To do so I pinned it into a stack of sheets of paper, then used tape to make it stick to the stack, then used the Dremel to sand it flat.
The next step is tricky as well: you ll need to enlarge the hole in the movement plate so that the protruding part of the wheel can go through.
Looking at the picture of the plate that is the small 1 mm hole on the left of the plate next to central hole.
I picked up the tiniest bit on the Dremel, put it in that hole and gently pressed the plate so that the bit would grind the hole and extend it.
The plate is quite hard versus the Dremel bit but in about 2-3 mins the hole should be large enough to accommodate the wheel.
Last step is easier just put a tiny bit of glue on the back of the wheel and sandwich it between the movement and the movement plate.
Check before with your dial that the sub dial are correctly aligned !
Ok at this point I am struggling with 3 things:
1. I need the rust powder to add more brown to an overly redish rust on my dial
2. I need to put some feet back to my dial. (My first attempt with guitar string failed as I can't get the string to glue well to the plate), Gluing the dial is too permanent, tape not ideal... Maybe some non permanent adhesive ???
3. I tried to fit my sub dial hands. It is a nightmare - feel like the yuki hands are smaller than my original hands. I will try to investigate.
