A bit late, but I have a partial answer and am looking for the rest of the story. I was able to get the time adjustment knob off by (1) pulling the knob out, (2) grabbing the stem with the first set of pliers, and (3) grabbing the knob with a second set of pliers, then (4) unscrewing the knob. It took a serious amount of torque and fought me through about 3/4 of the way.
What I don't see, however, is to remove the knob that is through the center of the lens, the one with the green pointer. Can anyone help with that? Thanks
