After replacing a faulty double corrector on a 7750-GMT movement, the quicksetting for date and GMT sometimes work and sometimes the double corrector doesn't seem to engage with either the DW or the GMT gear. It's like the spring isn't properly connected to the double corrector to put it back in place.
I also suspect the double corrector to work a bit different than on a standard 7750, so I have no reference on how to install it properly.
Does anyone have a picture showing how to install the double corrector and connect it with the spring attached on the date plate?
In what order do I install the date plate, DW, GMT gear and double corrector?
