I would correct and add a little.
In ceramics, currently out of production are possible: PAM292, PAM643, PAM508, PAM580, PAM607, and VSF models that may or may not be sold, their availability is now very flexible: PAM438, PAM441 and PAM1441, which, in fact, exceeds GEN in thickness, in fact .
Speaking of carbotech, these are PAM616, PAM661, PAM1616, PAM1661, PAM960, PAM961, PAM979, PAM1039, PAM1118 and finally the PAM799, which only has a carbotech bezel, same as PAM1663, which should be fibratech, but carbotech bezel (rep is made entirely of carbotech, same as PAM1119 but different texture and color)
And there are a huge number of PVD and DLC black models left, the actual ones of which are only HWF: PAM629 and PAM779. There are a lot out of production at the moment, but I won't list them all, just buy them if you see m2m. It doesn't go through often, but dozens of models have been made.
