Need help with 145.012 Lume

big case

that's the point

but also: it is a very strong magnifikation (and sometimes bad digital camera or smartphone is
suboptimal)

if we check our own watches in a way like this (same magnification) we - perhabs - also think about, what we see

it would be good, if a really experienced person could check by own eyes by loupe

You have a nice 57 y/o Speedmaster which looks very good and original from the various parts weve seen.
I also think the lume is good
The various over analyzed little marks in red circles are likely on crystal.
I would stop worrying about it at this point and put away the loupe and enjoy your nice watch

All original dont forget in the 60’s 70’s machinery was not so precise as now
