I made them in a program called daz3d
https://www.daz3d.com/genesis-8-1 (its free to start with basic stuff, otherwise they have a marketplace where they make their money)
here is another market place
https://www.renderotica.com/
And the 3D watch models:

I gave up on all of this due to the amount of time it takes, as I was still learning. Some people make a living from NSFW animation, it's crazy!
I suppose the amount of content you look for, as it's very niche, what I like, is femdom while she wears a chunky Rolex does it for me - but this content is very very rare, so making it in 3D or even AI, would be quicker.
