I agree with your statement about untouched v refinished and mentioned it because the sellers statement "The case is very thick , and still has very nice bevels on the lugs."
What are your concerns with the insert?
It just looks (to me) like a replacement. Same as some of the others posted here. a 1960's bezel tends to show it's age. I could be wrong.
Thanks guys!
I really like the matt dial and prefer one without the white gold marker surroundings.
To bad that it's really hard to figure out if a GMT is original or not..
The case appears refinished to me, but impossible to tell from those small images. This is mine from 1965 as a reference, I feel pretty confident it was never touched.
