Parts were collected over the last 2+ years.
The crown is a correct gen 'service/replacement' part. All crowns these days are 703's from a new/service perspective. Remember, my MO is 'freshly serviced look from RSC'. I am not a period-purist, as I feel it is unrealistic for a 'regularly worn' watch. So the hands and insert are lumi for example, and crown is modern 703. (True, it might be a little too clean/pristine for a late 70's rendition, but I like the idea of letting it age up naturally starting now)
(edit, went back and looked at photos above -vs- in person, crown has a 'ding' in it that is reflecting/blurring, also either silicon smudge or finger oil-- so I see why you said that. In person the detail is sharp, crisp, and GEN 703.)
