I'm looking for a Speedmaster with a 321 movement. This would be my first vintage watch. I came across the following 105.012 from 66. Ho wever there is not much patina on the lume.
Does not look like a service dial to me, per your title, but lume looks washed as you mentioned and the dial is damaged on the edges. Not an attractive dial to me and for me the dial is a lot of what I am buying. YMMV.
