I have three modded YUKI 3135 with these specs:
GEN Rolex keyless (setting lever #220; jumper for setting lever #230; yoke for sliding pinion #240; yoke for setting wheel #266; cover mechanism mounted #268; setting wheels 2pcs #250; sliding pinion #205; winding pinion #204)
GEN Rolex mainspring
One is in my franken Deep Sea and one in my franken Sub-C. I have one spare. Might use it someday. But all I can say: damn reliable now.
