audemars piguet vintage watch question

[bimmerm3]

I just recently acquired this Audemars Piguet vintage watch and searched all over the internet but can’t seem to find the model number

By any chance would anyone know?

Also, the band is a tiny bit tight in me. Is there anyway to change out the clasp so it’s a little bit looser?

I know its an ellipse, that much is for sure.
Hope this link helps a bit..

The second “A” in the audemars on the face is a tiny bit faded as in this picture

Would this mean the watch might not be authentic?

This watch is a bit old tho.

Could just be an old faded dial, wouldn't be unusual. Maybe take it to the Westime AD, perhaps they can tell you what you have there.
