Hello.
In general, this forum is better to use not so.
Each model has a discussion, and sometimes more than one, and using the keyword search bar, you can find them.
The problem may be that you will find a lot of meaningless threads with questions, and at best, not relevant answers, and this is the reason why creating such threads is not the best way.
For now, you will learn how to do this, and I will try to make the thread useful, although not relevant after a while.
Now you can buy PAM1312 TTF, it's far from perfect, here's a thread discussing it:

https://forum.replica-watch.info/forum/panerai/10335445-ttf-new-pam1312-pam1314/page2
And a review of its closest relative PAM1314 TTF, where the advantages and disadvantages are well disclosed, which are generally equal for these models, and a lot of good photos, although, I must admit, in my opinion PAM1314 TTF is made better:

The best before it, and generally recognized as the PAM1312 VSF, it became one of the best and most accurate models of 2020, but the VSF is now working and not, and you will have to contact all TDs to check availability:

https://forum.replica-watch.info/forum/panerai/9505424-new-release-pam1312-vsf
And here is a very useful comparison of PAM1312 VSF on the case part and some parts with GEN:

Before that, the previous generation PAM1312 with lume patina and transparent caseback was produced by v6f and zf factories, you can find these themes yourself. Because of the transparent caseback and the A7750 with a decorative panel, this watch is generally worse, but still good.
You will find links to the threads yourself, and you will find m2m for the watch, because these factories no longer exist.
Also, you should pay attention to the PAM312 VSF and find the thread that originally compared the PAM312 and the old generation PAM1312 in order to generally understand the essence of the lineup and the principle of choice.
In general, it just doesn't work out that way. Read, find out, join our ranks, and ask questions that have never been asked, but rather find answers yourself, formulate them, and write not questions, but answers. And then the forum will become truly informational.
Good luck to you.
