Photographing 1970s Ultra-Chron 8309

So, I got this beautiful 1970s Ultra-Chron 35mm on a mesh bracelet. I will shoot with a strap later.
Also, I have a few shots where I compare it with the revival model. Revival has a bit fatter and higher bezel, a larger crown (proportionally), and a sapphire crystal that is a bit better to photograph.
I wish I could open this watch to photograph the movement, but not sure if a local watchmaker can do this without risking breaking the crystal.
This watch should have caliber 6651 and perhaps reference 8309.

Absolutely fabulous 😀

And I have not cleaned any of these photos. Just color correction, etc. So, brutally honest look.

Here are a few close-ups. You can see the full size when you click on the image.
