Thoughts on the condition of this vintage sub?

[Eph]

I'm very actively looking at some vintage Tudor subs and found one, but the photos leave me with some questions.

My first question is about the dial's aging. Here's a photo:
The aging (30 years) seems to have the "Swiss" lettering fading away, or into the lume. Is this kind of aging normal? I wish the lettering was crisper, but I don't know much about whether or not this kind of aging is normal, advanced, desired, frowned upon, etc.
Also, any other thoughts on the condition of this dial?

Second question is about the lugs. The seller says it wasn't polished, but it seems to me that maybe there was a polishing a while back as the springbars seem to be different depths from the lug holes. I'm very inexperienced here, so I'm seeking some thoughts from someone who may know more about this than me. Here are some photos of the different lug holes:


Seems like the springbar isn't far from popping out (bottom right)


Same as above, seems like the springbar isn't far from popping out (top right)


Seems like the spring bar is more recessed than in the other photos (top left)


Looks like the springbar is healthily recessed in the lug (bottom left)

Lastly, how's this for 30-year stretch? I know a jeweler who can fix this up nicely, but I'd factor the price of that into my negotiations if this is considered a lot of stretch.


Or, any other thoughts on the condition of this watch, given that it's 30 years old? Anything I can do short of a polish or dial restoration (which I'm not interested in) to make it a nice keeper, as I want to hang on to this for a long long time? It's recently been serviced, too.

I really appreciate all your input and expertise here as I'm just beginning to get into this world!

Thanks!
