1966 Blacklung Doxa SUB 300 Professional

I just got my sub 300 back from the shop. The dial is an almost perfectly executed redial and the hands are from a 300T but otherwise everything is original. My watch woman kept it for 2 years as she had issues with the movement so i had to source another movement to use for parts. It is now working perfectly well and is the perfect wearer. It even passed the waterproof test. I really lucked out on this one when i bought it, as genuine sub 300s are hard to get and the redial makes it all the more attractive and i have zero concerns about damaging it.
Case has never been polished, case back has a faint serial number and crown is the original Doxa branded one. Crystal is the correct raised one but i do not know if it is original.
Bezel is beautiful and original but of course not the correct one for a black lung Doxa as the gradations are in meters not feet.

I have been wearing it non stop for 4 weeks and the timekeeping is spot on. Those old Doxas sure are reliable.
