Yes the dial is the same and of quality here is OK! But this is a 5512 Gilt Underline Dial and no 5513.
My used case was one of the new Cartel and only the insert of yuki.
Hands from Clark, relumed and reworked.
Crown and Tube, Athaya 700.
Plexi, T19 sternkreuz.
Yes for the 2451 you need a movement ring!
99% you do not have to drill your case around the Athaya tube.
