Can anybody tell me more about this model:

a 1973 Santos. They came in steel and gold as well as just gold. Also in round and square case shapes. But usually with metal bracelets.
Wasn't there a re-issue in the late 1980s?

I am in the dark
Anyone out there who can be of help?
a couple of my reference Cartier books and have no conclusively id.
I assume the photo is not skewed and this is an ellipse shape?
I still have a few more tomes to check.....do I get paid by the hour?

Hi MTF
You're a real gem.
Need all your help to uncover this 'mystery'
Its elliptical(vertical).
Bought it 20 years ago.
Thanks for the info.
I believe its like looking for a needle in a haystack unless
we can locate this 'P'
Don't really know many of them.
