Looks fine, except the lume that fell out. There are plenty of good and cheap pieces with this dial variant, i'd let it pass, unless you're a reluming expert.
There were not that many NVCh issued, and i would guess they were issued to officers who would take good care of them, along with boxes and paperwork. Kind of like, if they give you a medal of a Hero of the Soviet union, you don't throw away the box, do you?Why not? I would imagine many good watches are w/o these tins.
