I have seen two with silver dial, one with blue tachy one grey/black, both as Paul said with the Hamilton bridge.
These watches have been final exam pieces to become a watchmaker, task was to create a unique piece changing dial print, tension rings, movement parts....
Any more out there, photos please !
